Melasma & Dark Spots: How to Tell the Difference and Choose the Right Skincare

"Dark spots" is a description, not a diagnosis. Brown patches across the cheeks, marks left behind by a spot, red-pink shadows after acne and isolated freckle-like spots can all look similar in the mirror, and they do not all respond to the same ingredients. This guide explains the patterns people most often describe, why sun protection matters more here than almost anywhere else in skincare, which ingredient directions have the strongest evidence, and which products you probably do not need to buy.

What people usually mean by "melasma and dark spots"

Most people arrive at this subject with the same sentence: my skin tone is uneven and I want it evened out. That is a completely reasonable goal. The difficulty is that the phrase covers several different things happening in the skin, and a product aimed at one of them can be a poor match for another — or, on skin that is currently irritated, actively counterproductive.

The American Academy of Dermatology makes this point in its own guidance on fading dark spots: it advises continuing to address the underlying cause — treating the skin condition that produced the marks — rather than only working on the discolouration itself. That single idea reorders most people's routines.

So rather than looking for one universal dark-spot product, it is usually more useful to consider which pattern most closely resembles what you are seeing, check whether your skin is currently comfortable enough to treat, and then choose one ingredient direction and give it real time.

Which pattern most closely resembles what you are seeing?

Notice what is missing from that table: skin type. Whether your skin is oily, dry or combination mainly changes which vehicle and level of moisturisation feel comfortable. Sensitivity and barrier state are separate dimensions, and they are what more directly change how cautiously an active should be introduced. Neither changes the underlying pigment biology. We come back to texture later, in the section on choosing a formula, because that is where it genuinely belongs.

When a dark spot should be looked at rather than treated

Before any of the rest of this is relevant: cosmetic skincare is for benign, stable pigmentation. Some pigmented marks need a medical eye, and a brightening routine is exactly the wrong response to them.

Separately from pigmentation, stop self-treating and seek assessment if you have deep, painful or scarring acne, spreading redness or warmth, any eye involvement, or a persistent unexplained rash. And if a mark simply worries you, that is reason enough to have it looked at — you do not need to justify it.

Why melasma-like pigmentation behaves differently

Marks left behind after a spot are, broadly, pigment that has already been made and now has to clear. Melasma-like pigmentation is different: it involves skin that keeps being prompted to make more pigment. That distinction explains most of what people find frustrating about it.

A 2026 international expert consensus on managing melanin hyperpigmentation disorders, published in the Journal of the European Academy of Dermatology and Venereology, describes management as needing to address more than pigment cells alone — the surrounding skin environment matters too, including blood vessels and other cell types. It also notes that these conditions are prone to treatment resistance and recurrence, and that some treatments can make pigmentation worse.

Three practical consequences follow. Improvement usually needs sustained, unglamorous consistency rather than a strong product used briefly. Recurrence is common, which means a maintenance phase matters as much as a treatment phase. And anything that inflames the skin can feed the same process — which is why the next section comes before the ingredient section rather than after it.

If your skin is currently stinging or peeling, start here

Adilsons Beauty works barrier-first: we support the skin barrier before adding treatment actives. In pigmentation that is not just a general preference, it is the specific risk. Inflammation is one of the routes by which brown marks appear in the first place, so a routine that irritates the skin in pursuit of faster brightening can quietly work against itself.

The AAD puts it plainly in its dark-spot guidance: use skin care products that are gentle on your skin, and if a product burns or stings when you apply it, stop using it. Its melasma self-care guidance similarly recommends choosing gentle, fragrance-free products.

So if your skin is currently stinging from things that never used to sting, flaking, feeling tight hours after washing, or reacting to products it previously tolerated, the useful move is to pause the treatment products, keep cleansing gentle, moisturise, and keep wearing sunscreen. Sun protection stays. Everything else can wait.

For that settling period, a straightforward panthenol or ceramide moisturiser is usually all that is needed. In our range, Purito Seoul Mighty Bamboo Panthenol Cream 100ml is a lighter option and Anua 3 Ceramide Panthenol Moisture Barrier Cream 100ml a more cushioning one. If you already own a plain moisturiser your skin is happy with, use that — this is not a step that needs a new purchase.

Photoprotection is the foundation of pigmentation management

For pigmentation, sunscreen is not the thing you add at the end because you should. It is the foundation the rest of the routine sits on, and treating pigment without it is treating and undoing in the same routine. That is truest for melasma-like patches and sun-spot patterns; where acne is still active, controlling the acne matters at least as much.

Three things to protect against, not one

Most people think of sunscreen as UV protection, and UVB and UVA are both genuinely important. But there is a third band that matters specifically here. The 2026 international consensus states that sunscreens for these conditions must protect against UVB, UVA and high-energy visible light, and that all skin tones need good visible-light protection to prevent worsening.

Standard sunscreens are engineered to filter UV. They are not designed to block visible light. The pigments that do that job are iron oxides — which is why the AAD's melasma and dark-spot guidance specifically recommends a tinted sunscreen containing iron oxide alongside an SPF of 30 or higher. As the AAD notes, iron oxide appears among the inactive ingredients rather than the active ones, because only UV filters are listed as actives.

What that looks like in our range

Our range includes Beauty of Joseon Daily Tinted Fluid Sunscreen, in the shades LP100, MY210, MY220 and MN230. It is the most directly relevant product we carry for this purpose, and it is worth being precise about why — and about its limits.

What the manufacturer confirms. The formula uses zinc oxide at 20.9% as its only UV filter, and every shade lists iron oxides — CI 77491, CI 77492 and CI 77499 — among its ingredients. That is exactly the pigment combination the dermatology guidance is pointing at when it recommends a tinted sunscreen with iron oxide.

What we cannot tell you. We have not identified any published visible-light testing of this finished product, or any figure for how much visible light it attenuates. It contains the right pigments; nobody has published what that delivers in this formula. That distinction is the whole reason the section above explains that no visible-light protection factor exists yet. It also contains alcohol denat., which is worth knowing if your skin is reactive.

The shade question is real. Beauty of Joseon produces this in twelve shades. We carry four of them. The 2026 consensus is candid that tinted sunscreens suit only a limited part of the population precisely because shade ranges are narrow, and that they are often a poor fit for very light skin, very deep skin and Asian skin tones. If none of our four shades matches you, forcing one is the wrong answer — a mismatched tint gets applied thinly, as makeup, which defeats the point.

If the tinted fluid does not suit you

The consensus sets out the alternative directly: use a well-balanced UVB/UVA non-tinted sunscreen, and add an iron-oxide-containing makeup product matched to your skin tone. Two parts, two jobs:

• A high-SPF, strong-UVA sunscreen does the UV work. Beauty of Joseon Relief Sun Aqua-Fresh: Rice + B5 50ml is labelled SPF50+ PA++++, is fragrance-free, and uses a photostable filter set with strong UVA coverage in a light, fast-absorbing texture — a practical combination in warm, humid conditions. Beauty of Joseon Relief Sun: Rice + Probiotics 50ml is also SPF50+ PA++++ in a slightly more nourishing finish, and SKIN1004 Madagascar Centella Hyalu-Cica Water-Fit Sun Serum 50ml is SPF50+ PA++++ in a watery serum texture if you want the lightest of the three.
• An iron-oxide-containing base worn on top can serve as the visible-light layer. TIRTIR Mask Fit Red Cushion 18g lists iron oxides (CI 77491, CI 77492, CI 77499) in its official ingredients and has the widest shade range we carry, which makes tone matching realistic across a broader range of complexions than the tinted fluid's four shades. The same honesty applies: it fits the consensus description of an iron-oxide makeup layer, but we have not identified finished-product testing quantifying its visible-light protection. It is makeup, labelled SPF40 PA++, so it does not replace your sunscreen — and it contains fragrance.

You can also combine the two approaches: an SPF50+ sunscreen for UV, with the tinted fluid or a matched cushion over it for the visible-light layer. Beauty of Joseon's own guidance suggests reapplying with a non-tinted sunscreen through the day, which fits that pattern.

Quantity and reapplication matter more than people expect

A sunscreen only delivers what its label says if you apply enough of it. The 2026 consensus gives a usable benchmark: apply an even layer of roughly a quarter of a teaspoon for the face, and reapply at least twice a day if you are regularly outdoors. The AAD's dark-spot guidance suggests reapplying every two hours, and after swimming or sweating, and pairs sunscreen with a wide-brimmed hat and avoiding the strongest part of the day.

In a warm, humid climate with strong sun for much of the year, sweat and rubbing are the practical enemies of that plan. Two things help: choosing a texture light enough that you will actually reapply it, and remembering that a tinted product used as makeup tends to get applied thinly, for looks, which is not the same as applying sunscreen properly.

The ingredient directions worth understanding

These are directions, not prescriptions, and the evidence behind them is not equally strong. One point applies to every ingredient below, so it is worth stating once: a study of an ingredient is not a study of a product. A trial showing that 4% niacinamide improved pigmentation does not prove that any particular serum containing niacinamide will do the same, because concentration, formulation, delivery and everything else in the bottle all matter.

Tranexamic acid

Tranexamic acid appears across a lot of Korean formulas and is one of the more interesting non-prescription directions. It is also a good test of whether we are willing to report evidence that is less flattering than the marketing.

A 2026 systematic review and meta-analysis in Dermatologic Therapy pooled 32 studies and 2,376 participants across 14 different comparisons. For its three main comparisons it found little to no difference between tranexamic acid and placebo, and little to no difference against hydroquinone, with substantial unexplained variation between studies and certainty rated from very low to moderate. The clearest signal was for tranexamic acid combined with hydroquinone versus hydroquinone alone — a prescription comparison, not a cosmetic one.

Two important caveats in both directions. That review pooled oral, injected and topical use together, so it is not a verdict on topical cosmetic tranexamic acid specifically. Equally, it does not license the confident claims made for tranexamic acid serums. The defensible position is that topical tranexamic acid is a reasonable, generally well-tolerated option worth trying — not a proven or clearly superior one.

It also means a higher percentage is not automatically better. Published formulations span a wide range, no optimum has been established, and a 6% product is not "stronger medicine" than a 2% one in any way the evidence supports. Choose on formulation, texture and tolerance rather than on the number on the front.

Azelaic acid

Azelaic acid is a logical direction to consider when pigmentation and active breakouts coexist, because it works on both rather than treating marks while spots keep forming. It has a longer clinical history in melasma than most cosmetic ingredients, though the strongest of that evidence used higher concentrations than cosmetic formulas contain — so a 10% cosmetic serum should be understood as a lower-strength route into the same ingredient, not as equivalent to prescription strengths.

It is also the pigmentation direction with the most reassuring position in pregnancy, which we come back to below. It can sting or tingle at first, which is why manufacturers advise building up slowly rather than starting daily.

Niacinamide

Niacinamide is genuinely useful and unusually well tolerated, and it supports the barrier as well as working on pigment transfer. The concentration point is the one that gets distorted in marketing: the direct human melasma evidence sits around 4–5%, and there is no good evidence that 10% or 20% performs proportionally better for pigmentation. Higher percentages mostly increase the chance of flushing or stinging in sensitive skin.

If a 10% or higher niacinamide product suits your skin and you like it, there is no reason to abandon it. But a high percentage is not a reason to choose one product over another for dark spots.

Alpha-arbutin

Alpha-arbutin is a gentle, straightforward option and its formulas are usually simple, which has real value if you are cautious about reacting. Its human evidence for melasma is more limited than for azelaic acid or tranexamic acid, so we would position it as a reasonable alternative rather than the strongest available direction. Under EU cosmetic rules alpha-arbutin is restricted to 2% in face products, which is why well-formulated products cluster at that level — a regulatory safety ceiling, not a proven optimum.

Vitamin C

Vitamin C is worth separating into two things that get sold as one. Pure L-ascorbic acid needs a low pH, which can sting and destabilises over time. Derivatives such as 3-O-ethyl ascorbic acid are formulated differently, are often gentler, and cannot simply inherit the evidence generated by L-ascorbic acid. Both are reasonable as antioxidant support alongside sun protection; neither is the clearest first choice for melasma-like pigmentation when irritation is a concern.

Kojic acid

Kojic acid appears in a number of brightening formulas, usually at low levels, and EU rules restrict it to 1% in face and hand products. Contact sensitisation is a recognised issue with it, so it is not our first suggestion for reactive skin, and it is often present as a supporting ingredient rather than the main event.

Retinoids and exfoliating acids

Both can contribute, and neither is a starting point. Retinoids work slowly on pigmentation — meaningful change in controlled studies took months, with irritation common along the way — which makes them a poor first move for someone whose barrier is already unsettled. They are more logical later, and particularly where acne or photoageing overlap.

Exfoliation is not mandatory for pigmentation, despite how often it is framed that way. Used sparingly it can help surface marks clear; used enthusiastically it creates exactly the inflammation that produces brown marks in the first place. If you are already using a pigment active, adding an acid is usually the point at which people tip from treating into irritating.

Which direction may fit which situation

Patterns overlap and people do not fit neatly into categories, so read these as starting points rather than rules.

Finding the pathway that fits your situation

This is where everything above converges. Rather than listing products by category, work through three questions in order — because the order matters more than most people expect.

1. Which pattern am I dealing with? This sets the ingredient direction.
2. What state is my skin in right now? This can override the answer to question one entirely.
3. Which formula suits my skin and my life? This changes the texture, not the active.

Note the priority. Skin state outranks skin type. Irritated dry skin and irritated oily skin get the same answer — wait — while comfortable dry skin and comfortable oily skin can use the same active in different vehicles. Pregnancy, recent procedures and current prescriptions override all of it.

Pathway 1 — If your skin is currently irritated

This pathway exists to stop you buying a treatment product today, so it comes first.

Come back to the pathway below once ordinary skincare feels comfortable again.

Pathway 2 — Melasma-like patches, skin currently comfortable

All of these sit on the same photoprotection foundation — a high-SPF sunscreen, with Beauty of Joseon Daily Tinted Fluid Sunscreen or a matched iron-oxide base for the visible-light layer where a shade suits you. That part does not change between the rows below. What changes is complexity, vehicle and how cautiously you start.

Pathway 3 — Brown marks after acne or inflammation

Here the first question is not which serum, but whether the thing that caused the marks has stopped.

Pathway 4 — Red or pink post-acne marks

This is the pathway where the most useful advice is to buy nothing from the pigment shelf. If the marks are predominantly red or pink rather than brown, a melanin-directed serum may be aimed at the wrong target, and there is no product in our range we would put forward as a treatment for that.

What is reasonable: keep cleansing gentle, keep the barrier comfortable with something like Purito Seoul Mighty Bamboo Panthenol Cream if you need it, keep wearing sunscreen so nothing darkens on top of the redness, and treat any ongoing breakouts. If the redness persists, that is a conversation with a healthcare professional rather than another purchase.

Pathway 5 — Isolated sun-spot-like marks

Consistent photoprotection is the strongest thing available to you here, and it works better as prevention than as correction. Established spots of this kind respond least well to cosmetic products, so the honest position is that a pigment serum may soften the contrast a little and may do very little.

If you want to try something, The Ordinary Alpha Arbutin 2% + HA or the SKIN1004 Tone Brightening Capsule Ampoule are reasonable low-irritation choices — with the expectation set low. We would not push tranexamic acid at this pattern simply because the packaging says dark spots. And a single spot that is changing, growing, or looks different from your others belongs in the red-flag section above, not in a routine.

Adjust the texture, not the pigment biology

This is the compact version of the skin-type question, and it is deliberately short, because skin type does less work here than the industry implies.

Building the routine

The structure below is deliberately short. Most people's pigmentation routines fail because they contain too much, not too little.

Morning

1. Gentle cleanse, or just water if your skin is dry
2. Moisturiser, if you use one
3. Sunscreen — generously, roughly a quarter-teaspoon for the face, and reapplied through the day when you are outdoors
4. If you are using an iron-oxide base for visible-light protection, it goes on last, over the sunscreen

Evening

1. Cleanse
2. Your one pigment-directed product
3. Moisturiser

Some pigment products are fine in the morning too — azelaic acid is often used twice daily, for instance — so follow the directions for the specific product you have bought rather than a general rule from an article.

Introduce one new thing at a time

As a cautious approach, we suggest starting a new leave-on treatment product at a low frequency — often two or three applications a week where the manufacturer's directions allow — building up as your skin tolerates it, and not beginning a second new active until you know how the first one behaves. That is our conservative onboarding suggestion rather than a clinical guideline, and the directions on the product you buy take precedence over it. Some brands are explicit about this: Anua directs starting its azelaic serum once or twice weekly with one or two drops. The reasoning is not caution for its own sake. If you start three things at once and your skin reacts, you have no way of knowing which one caused it, and you will probably abandon all three. If it goes well, you equally have no idea what helped. Patch-test on a small area first, and give any new product several weeks before judging it.

What you may not need to buy

Commercial honesty means telling you when the answer is not a product, so here is the list of things people routinely buy for pigmentation that they usually do not need.

• A separate niacinamide serum, if your chosen pigment product already contains niacinamide. Most of the options above do. Adding another is duplication, not reinforcement.
• A brightening toner and a brightening serum and a brightening cream from the same range. Ranges are built to be sold together, not because pigmentation needs four steps.
• An exfoliating acid, in most cases. It is not a required part of a pigmentation routine, and over-exfoliation is one of the more common ways people make marks worse.
• A replacement for a product that is working. If you already own something with a suitable ingredient and your skin is comfortable with it, use it up first. Nothing here is a reason to bin a functioning product.
• Anything at all, this week, if your skin is currently stinging or peeling. Sunscreen and a plain moisturiser, then reassess.

There is also a technique point that outperforms most purchases: applying enough sunscreen, and reapplying it. Someone using a modest serum with thorough sun protection will generally do better than someone using an excellent serum with a thin morning-only layer of SPF.

What to realistically expect

Pigmentation is slow, and the honest timeline depends on which pattern you have. We are not going to give you a number of weeks, because the evidence does not support one universal figure and the factors that vary — the cause, the depth of the pigment, sun exposure, whether the original trigger has actually stopped, the product, the frequency, your tolerance and your consistency — matter more than any average.

There are limits worth naming. Cosmetic skincare works mostly at the surface, and pigment sitting deeper in the skin responds more slowly and less completely. DermNet notes that peels, lasers and intense pulsed light may help surface pigmentation but can also aggravate it by injuring the epidermis, and are not effective for deeper pigment. The 2026 international consensus similarly advises that resurfacing procedures be used cautiously. That is not an argument against professional treatment — it is an argument for it being chosen by a clinician who has examined your skin, rather than pursued as an obvious next step when a serum has not delivered.

When to see a healthcare professional

Seek assessment from an appropriate healthcare professional if a pigmented spot is changing in size, shape or colour, has an irregular border or more than one colour within it, looks clearly different from your other spots, or itches, bleeds, crusts or will not heal. The same applies to severe, painful or scarring acne, spreading redness or warmth, any eye involvement, and a persistent unexplained rash.

Beyond urgency, professional assessment is simply the more useful next step in several ordinary situations: when you cannot tell which pattern you are dealing with, when pigmentation has not responded to months of consistent sun protection and one appropriate product, when it keeps returning, when you are pregnant or breastfeeding and want a clear answer on what is appropriate, or when you are considering a procedure. A dermatologist can distinguish between things that look alike on a face but not under examination.

Checking availability at Adilsons Beauty

Our range changes and availability is dynamic, so any product mentioned here may or may not be available on a given day. Please check the current status on adilsons.mu rather than assuming — the product links above go to our search so you always see what is live now.

If something you want is showing as out of stock, go to that product's page and click Notify Me, then enter your email address. We restock frequently — roughly every three weeks as a general cycle. That is how often we bring stock in overall, not a guaranteed restock date for any individual product, so please read it as an indication rather than a promise.

Two things worth knowing. If around three weeks pass and you still have not received a restock notification, message us and mention that you already submitted your email and have been waiting about three weeks — we can then look into it and confirm the situation for you. And if a product matters to you, you are welcome to message us after registering your interest to tell us you would like it restocked. That helps us see real demand when we plan what to bring in.

Frequently asked questions

Is a higher percentage of tranexamic acid better for dark spots?

Not on the current evidence. Published studies use a range of concentrations and formulations, and a 2026 systematic review and meta-analysis found a modest overall benefit for tranexamic acid over placebo rather than a dose-ranking. No optimum concentration has been established, so a 6% product is not demonstrably stronger than a 2% one. Choose between products on formulation, texture and how well your skin tolerates them, not on the number printed on the front.

Do I need a tinted sunscreen for melasma?

Tinted sunscreens containing iron oxides are specifically recommended by the American Academy of Dermatology because they add protection against visible light, which standard sunscreens are not designed to block. We carry Beauty of Joseon Daily Tinted Fluid Sunscreen in four shades, which contains iron oxides, though its labelled SPF is 40 or 30 depending on the market rather than 50. If no available shade matches you, the 2026 international consensus suggests a well-balanced UVB and UVA sunscreen with an iron-oxide-containing makeup product matched to your skin tone worn over it.

Is tranexamic acid safe to use during pregnancy?

Nobody has established that, and we will not claim it either way. Melasma studies routinely exclude pregnant and breastfeeding participants, so pregnancy-specific evidence for topical tranexamic acid does not exist. Low expected absorption is a reasonable assumption, not proof of safety. Azelaic acid has the more reassuring professional position among pigmentation ingredients, and retinoids should be avoided. Please discuss any pigmentation product with your doctor or midwife.

My post-acne marks are red rather than brown. Will a dark-spot serum help?

Possibly not, because red and pink marks after acne reflect a redness pattern rather than excess pigment, so a product designed to reduce melanin may be aimed at the wrong target. Gentle care while the skin recovers, along with controlling any ongoing breakouts, is usually more sensible than escalating brightening actives. If the redness persists or the pattern is unclear, a healthcare professional can tell you far more than a product description can.

Can I use two brightening serums at once for faster results?

We would not suggest it. There is no good evidence that layering several cosmetic brightening products outperforms one appropriate product, and there are two real costs: overlapping ingredients you are paying for twice, and no way to identify which product caused a reaction if your skin becomes irritated. Irritation can itself contribute to pigmentation, so a more complicated routine can work against the result you want.

How much sunscreen should I actually be applying?

More than most people do. The 2026 international consensus on pigmentation disorders suggests an even layer of roughly a quarter of a teaspoon for the face, reapplied at least twice daily if you are regularly outdoors, while the American Academy of Dermatology advises reapplying every two hours and after swimming or sweating. Shade, a wide-brimmed hat and avoiding the strongest part of the day all add meaningful protection alongside the product.

Will my dark spots come back after they fade?

They can, particularly with melasma-like pigmentation, which has a recognised tendency to recur. That is why ongoing sun protection matters more than any treatment phase, and why maintenance is part of the plan rather than a sign that something failed. Marks left after acne or irritation are less likely to return in the same place, provided the original cause has genuinely stopped.
