Dealing with stubborn dark spots and uneven tone that linger long after a breakout can be incredibly frustrating. This potent serum combines a high concentration of 15% Niacinamide with Tranexamic Acid and Glutathione to create a multi-pathway solution for hyperpigmentation, enlarged pores, and excess oil—concerns particularly common in Mauritius' sunny, humid climate.

• Who It's For: Individuals with oily, combination, or normal skin struggling with stubborn dark spots, post-inflammatory hyperpigmentation (PIH), sun spots, melasma, enlarged pores, and rough skin texture.
• What It Is: A lightweight, water-based serum with a powerful blend of 15% Niacinamide, Tranexamic Acid, and antioxidants.
• What to Expect: With consistent use, skin appears brighter, more even-toned, and smoother. The appearance of pores may be reduced, and surface oiliness can become more balanced. As this is a high-strength formula, a patch test is essential before first use.
• Will Not: Change your natural skin colour or provide instant results. Fading hyperpigmentation takes patience and consistent sun protection.

Integrate this serum into a simple, effective routine:

1. Cleanse: Start with a clean face.
2. Treat with This Serum: Apply 2-3 drops to your face and neck, patting gently.
3. Seal & Protect: Follow with your daily sunscreen in the morning or a moisturiser in the evening.

Mindful Tip: If you already own a similar brightening serum, finish it first to prevent waste and give your skin a clear chance to show results from one product at a time.

In the morning, this serum helps protect against environmental damage while controlling oil.

• Step 1: Cleanse — Wash with a gentle cleanser.
• Step 2: Treat with This Serum — Apply 2–3 drops. Its antioxidant properties provide an extra layer of defence under your sunscreen.
• Step 3: Moisturise (Optional) — If you have dry skin or your sunscreen isn't hydrating enough, apply a lightweight moisturiser.
• Step 4: Protect — Finish with a broad-spectrum sunscreen (SPF 30 or higher). This step is non-negotiable when treating hyperpigmentation.

Your skin's repair cycle is most active at night, making it an ideal time to use targeted treatments.

• Step 1: Double Cleanse — Start with an oil-based cleanser to dissolve sunscreen and makeup, then follow with a water-based cleanser.
• Step 2: Treat with This Serum — Apply 2–3 drops to target pigmentation and texture while you sleep.
• Step 3: Moisturise — Lock in the serum and support your skin barrier with a suitable moisturiser.

• Amount: Use 2–3 drops for the entire face and neck. A little goes a long way.
• Frequency: If you're new to high-strength niacinamide, start by using it once daily in the evening for the first 1-2 weeks. If your skin responds well, you can increase to twice daily (AM and PM).
• Method: After cleansing and toning, apply the drops to your fingertips and gently pat the serum onto your skin until absorbed. Avoid rubbing. Wait 30-60 seconds before applying your next product.
• Important Tip for Beginners: Due to its potency, a patch test is crucial. If you experience persistent redness or irritation, reduce frequency to every other day or mix a drop with your moisturiser to dilute it.

This serum can be used daily, but if you also use other strong actives like retinoids or exfoliating acids, it's best to alternate them to avoid irritation.

Example PM Schedule with Multiple Actives:

• Monday: This Serum
• Tuesday: Retinoid (or other strong active)
• Wednesday: This Serum
• Thursday: Retinoid (or other strong active)
• Friday: This Serum
• Saturday: Hydration/Barrier Repair Night (no strong actives)
• Sunday: This Serum

Rule of Thumb: Avoid using this serum in the same PM routine as strong exfoliating acids (AHA/BHA) or prescription-strength retinoids to minimise the risk of over-stressing your skin barrier.

• Immediate: Skin may feel smoother and appear more hydrated upon application.
• Within 2–4 Weeks: You may notice a reduction in surface oiliness and an initial improvement in overall skin radiance. Some users may experience "purging" (a temporary increase in small breakouts) as niacinamide helps clear pores; this should subside.
• After 4–8+ Weeks: With consistent daily use and diligent sun protection, you can expect a more noticeable reduction in the appearance of dark spots, post-acne marks, and an overall more even skin tone. Skin texture should feel smoother.

Myth: "I can scrub away my dark spots with harsh physical scrubs."

Reality: This is a common mistake that can worsen hyperpigmentation. Abrasive scrubbing can cause micro-tears and inflammation, signalling your skin to produce even more melanin as a protective response, making dark spots darker. This serum offers a safer, more effective alternative by using ingredients like Tranexamic Acid and Niacinamide to chemically inhibit and fade pigment from within, without causing physical trauma to the skin.

• ✅ Works Well With:
  • Hyaluronic Acid, Snail Mucin, Panthenol, and Centella Asiatica: These hydrating and soothing ingredients help to buffer the high concentration of niacinamide and support a healthy skin barrier.
  • Sunscreen: An absolute must. Using this serum without daily sun protection is counterproductive, as UV exposure will create new dark spots.
• ⚠️ Use With Caution:
  • Retinoids (Retinol, Tretinoin) and Exfoliating Acids (AHA/BHA): Avoid using them in the same routine (e.g., at the same time of day). Alternate their use (e.g., this serum in the AM, retinoid in the PM, or on different nights) to prevent potential irritation and a compromised skin barrier.
  • High-Concentration Vitamin C (L-Ascorbic Acid): While not a definite conflict, it's safest to use them at different times (e.g., Vitamin C in the AM, this serum in the PM) to ensure optimal pH for each and minimise any potential for redness in sensitive skin.

• 🟢 Ideal For: Oily and Combination skin types will benefit most from the sebum-regulating properties of 15% Niacinamide.
• 🟡 Good For: Normal skin types looking to address hyperpigmentation and improve overall skin tone.
• 🟠 Use with Care: Dry skin types can use this serum but must follow up with rich hydrating layers and a good moisturiser to avoid potential dryness. Sensitive skin types should approach with caution due to the high active concentration. A thorough patch test is mandatory, and starting with use every other day is recommended.

• Post-Inflammatory Hyperpigmentation (PIH) - Dark marks left after acne or inflammation.
• Melasma & Freckles - Hormonal or sun-induced brown patches.
• Sun Spots & Age Spots - Discoloration from UV exposure.
• Uneven Skin Tone & Dullness - Lack of radiance and blotchy complexion.
• Enlarged Pores & Excess Sebum - Helps to refine pore appearance and balance oil production.
• Rough Skin Texture.

Key Actives Explained:

• Niacinamide (15%): A very high concentration of Vitamin B3. It works by interrupting the process that transfers pigment to your skin's surface, helping to fade dark spots. It also regulates sebum production, strengthens the skin barrier, and provides anti-inflammatory benefits.
• Tranexamic Acid (3%): A powerful ingredient known for its ability to target hyperpigmentation, particularly stubborn forms like melasma and sun spots, by interfering with melanin production pathways triggered by UV light.
• Glutathione: A master antioxidant that helps to brighten the complexion and protect skin cells from oxidative damage, further supporting an even skin tone.
• Ascorbyl Glucoside: A stable form of Vitamin C that provides antioxidant benefits and contributes to brightening the skin.

• Fragrance: This product is fragrance-free. It contains no added artificial fragrances ("Parfum") or fragrant essential oils.
• Scent Profile: It has a neutral, barely-there scent typical of active-based formulations.
• EU Allergens: Based on the declared ingredient list, this formula is free from the 26 common allergens regulated by the EU.
• Fungal Acne (Malassezia Folliculitis) Note: This formula is generally considered suitable for those with fungal acne concerns, but it contains Fructooligosaccharides, which can be a potential trigger for a very small subset of individuals. A patch test is always recommended.

Patch Test Protocol: Before using for the first time, apply a pea-sized amount to a small, clean area of skin, such as behind your ear or on your inner arm. Wait 24-48 hours. If you experience any severe redness, itching, or irritation, do not use the product.

• For external use only. Avoid direct contact with eyes.
• Do not apply to broken, wounded, or irritated skin.
• Due to the high concentration of Niacinamide, some initial tingling or mild redness is possible, especially for new users. This should subside. If it persists or worsens, discontinue use.
• Pregnancy & Breastfeeding: There is insufficient published data on the use of high-concentration Tranexamic Acid during pregnancy or breastfeeding. It's best to consult with your doctor before use.

• Texture: A lightweight, slightly viscous watery serum.
• Feel: Spreads easily and absorbs quickly into the skin without feeling heavy or greasy.
• Finish: Dries down to a natural, comfortable finish. May feel slightly tacky for a minute before fully absorbing.
• pH: While not officially disclosed, formulations with Niacinamide and Tranexamic Acid typically have a pH between 5.0 and 6.5 to ensure stability and efficacy without causing irritation.

• Issue: My skin feels red or tingly after application.
  Solution: This can be normal for a high-strength serum. Reduce usage to every other night for 1-2 weeks. You can also "buffer" it by applying it after your moisturiser, or mixing one drop into your moisturiser to dilute its strength as your skin adapts.
• Issue: The product is pilling or balling up.
  Solution: You're likely using too much product or not allowing enough time for it to absorb before your next step. Use only 2-3 drops and wait at least 60 seconds before applying moisturiser or sunscreen.
• Issue: I'm breaking out more after starting the serum.
  Solution: You could be experiencing "purging," where the increased cell turnover brings underlying congestion to the surface. This typically appears as small breakouts in your usual problem areas and should clear up within 2-4 weeks. If breakouts are in new areas, widespread, or cystic, it might be an irritation response, and you should stop using the product.

This serum is an excellent choice for the Mauritian climate, where high humidity and intense sun exposure are major contributors to hyperpigmentation and oily skin concerns.

• Humid Summers: The lightweight, non-greasy texture is perfect for hot and sticky weather. The high concentration of niacinamide helps regulate excess sebum production, leading to less shine throughout the day.
• Drier Winters/Air-Conditioned Environments: While still effective, you may need to layer a more hydrating serum or a richer moisturiser on top to prevent any potential dryness from the high active content in less humid conditions.
• Sun Exposure: As this serum works to fade pigmentation, it's crucial to pair it with a high-SPF, broad-spectrum sunscreen every single day in Mauritius. Sun exposure will reverse its benefits and can create new dark spots.

• Brand-Published Data: Medicube conducted its own clinical trials on this serum. In one 4-week study with 22 participants, the brand reported a 17.3% improvement in deep, hidden hyperpigmentation and a 34.8% improvement in rough skin texture.*
• Ingredient Rationale: The efficacy of the key ingredients is supported by independent scientific research.
  • Niacinamide: Numerous studies confirm that topical niacinamide (typically at 2-5%) can significantly reduce hyperpigmentation, regulate sebum, and improve skin barrier function. This serum uses a much higher concentration of 15%.
  • Tranexamic Acid: Clinical trials have shown that topical tranexamic acid (at 2-5%) is effective in treating melasma and other forms of hyperpigmentation by inhibiting UV-induced melanin synthesis.

This serum is an excellent choice if your primary concerns are stubborn hyperpigmentation, enlarged pores, and oiliness. However, your skin is unique, and other options might be a better fit depending on your specific needs.

• For a Gentler Approach: Beauty of Joseon GLOW DEEP SERUM : RICE + ALPHA ARBUTIN — Choose this if you have sensitive skin or are new to brightening actives. It uses 2% Alpha-Arbutin and Rice Bran Water to gently fade dark spots without the high potency of 15% Niacinamide.
• For a Focus on Hydration & Repair: COSRX ADVANCED SNAIL 96 MUCIN POWER ESSENCE 100ML — Choose this if your main goal is to repair a damaged skin barrier, soothe irritation, and provide deep hydration. While it helps with skin texture and post-acne marks, it's less focused on intensive brightening.
• For an Anti-Aging Focus: The Ordinary RETINOL 1% IN SQUALANE 30ML — Choose this if your priority is targeting signs of aging like fine lines and wrinkles. Retinol accelerates cell turnover for significant texture renewal, which also helps with pigmentation but is a more potent anti-aging active. Note: Do not use this on the same night as strong acids or the Medicube serum.

Mindful Use: If you already have a comparable product at home, finish it first to avoid waste and get a fair read on results.

• Packaging: The serum comes in a 30ml glass bottle with a dropper applicator for precise, hygienic dispensing.
• Sustainability: The glass bottle is recyclable. In Mauritius, please rinse the bottle and place it in your glass recycling bin. The dropper is made of mixed materials and should be disposed of in the general trash.
• Storage: Store in a cool, dark place away from direct sunlight to maintain the stability and potency of the active ingredients.
• Travel: The 30ml bottle is travel-friendly and meets carry-on liquid limits. Ensure the cap is tightly secured to prevent leaks.

Here’s a summary of aggregated, unbiased feedback from real users on platforms like Reddit. (Note: These are individual anecdotes and not clinical results.)

"I’ve been using it for about a month now and my PIH has faded significantly. The texture is lightweight and absorbs fast without being sticky, which is great for my combo skin."

- Reddit, r/AsianBeauty (2023)

"It definitely helped with my pores and overall brightness. I didn't see a huge change in my deeper melasma spots, but my fresh post-acne marks look much better. It's a solid serum for general evenness."

- Reddit, r/SkincareAddiction (2024)

A Fair Caveat: "The 15% niacinamide was too much for me at first. I got some redness and had to scale back to using it every other day. If you have sensitive skin, definitely introduce it slowly!"

At Adilsons, we are committed to bringing you only the best and most effective K-Beauty products. We guarantee 100% authenticity on everything we sell. Our selection is carefully curated based on performance, ingredient quality, and suitability for the Mauritian climate, ensuring you get skincare that truly works.

Can I use this serum with Vitamin C?
Yes, but it's often best to alternate them to ensure maximum efficacy for both and to minimise any potential for irritation. A popular method is to use your Vitamin C serum in the morning and the Medicube TXA Niacinamide Serum in the evening.

Is 15% Niacinamide too strong for a beginner?
It can be. If you have never used niacinamide before, or have sensitive skin, it's highly recommended to patch test and start by using this serum only 2-3 times per week, gradually increasing as your skin builds tolerance.

Is this serum good for melasma?
Yes, it is formulated with ingredients known to be effective for melasma. Tranexamic Acid is one of the key topical ingredients recommended by dermatologists for managing melasma. Consistent use, combined with strict daily sun protection, is key.

Will this cause my skin to "purge"?
It's possible. Niacinamide can increase cell turnover, which may cause a temporary increase in small breakouts in areas where you are already prone to congestion. This purging phase should resolve within 2-4 weeks. If breakouts are severe, painful, or in new areas, it's more likely irritation, and you should stop using the product.

• Best For: Those with oily to combination skin looking for a powerful, targeted solution for stubborn dark spots, post-acne marks, and enlarged pores.
