PURITO SEOUL TXA 6 Niacinamide 10 Retinal Serum 30ml

Values: 100% Genuine (Adilsons policy) · Fragrance-Free (no Parfum in declared INCI) · FA-Conditional · Vegan-Friendly* · Cruelty-Free (uncertified)* · Pregnancy-Safe: No — contains a retinoid (see safety notice above).

Stock note: this SKU is currently out of stock in our catalog (0 units) despite showing as an active listing. This page remains published so returning customers and search visitors have accurate information while restocking is reviewed — check back or contact us on WhatsApp for restock timing.

PIH vs. PIE: this serum targets PIH (post-inflammatory hyperpigmentation — brown/tan marks from excess melanin) via tranexamic acid and niacinamide's melanosome-transfer-blocking action. It does not specifically address PIE (pink/red marks from damaged capillaries) — pair with centella-based products for that.

Pros: a genuinely well-dosed 6% tranexamic acid and 10% niacinamide combination; fragrance-free; reviewers describe it as unusually gentle for a brightening serum, with no tingling reported. Caveats: the "Retinal" in the name is present at an estimated trace 25ppm — do not buy this expecting meaningful retinoid resurfacing; it is currently out of stock.

Classification: YELLOW (14+ with guidance). This serum contains real clinical-strength actives (6% Tranexamic Acid, 10% Niacinamide) plus a trace retinoid — appropriate for teens with genuine hyperpigmentation concerns under adult guidance, not necessary for pre-acne, unblemished skin. The retinoid content, even at trace level, is a reason for caution rather than unrestricted use regardless of age.

Step 1 (When): PM, 3-4x/week to start. Step 2 (How much): 2-3 drops or 1 pump — shake the bottle 3-5 times first to disperse the encapsulated retinal beads evenly. Step 3 (How): Pat into clean, fully dry skin; wait 1-2 minutes before moisturizer.

Introduce this as the ONLY new product in your routine. Wait a full 14 days before adding anything else. This isolation window ensures you can identify whether any reaction is caused by this specific product.

1. Cleanser → 2. Toner (optional) → 3. TXA 6 Niacinamide 10 Retinal Serum (only if tolerated — retinoid content favors PM use) → 4. Moisturizer → 5. Sunscreen SPF50+ PA++++ (non-negotiable).

AM restriction: because this serum contains a retinoid (Retinal, even at trace level), retinoids are generally photosensitizing and best reserved for PM use, with daily strict SPF the following morning to protect the skin being treated.

1. Double cleanse (if wearing sunscreen/makeup) → 2. Toner (optional) → 3. TXA 6 Niacinamide 10 Retinal Serum (shake first, 2-3 drops, wait 1-2 minutes) → 4. Moisturizer.

Skin cycling integration: treat this as your Retinoid lane. Night 1: this serum. Night 2: a separate AHA/BHA exfoliant, if used. Nights 3-4: recovery, no actives.

Technique: Shake the bottle 3-5 times before every use — this formula suspends encapsulated retinal beads that can settle, and shaking ensures an even dose. Pat into skin, do not rub. Required skin state: clean, fully dry skin. Wait time: 1-2 minutes before moisturizer, since this is your retinoid-lane product for the night.

Cotton pad vs. hands: hands deliver roughly 100% of the product; a cotton pad absorbs approximately 30-40% into the pad itself. Use hands to get the full intended dose, especially given the already-trace retinal content.

This is an encyclopedia map of all product types. You do not use all of these daily. You select modules based on your skin state.

Global rules: viscosity ladder runs thinnest to thickest, water-phase before oil-phase, treatments before seals. Wait-time defaults: watery layers 10-20s, serums 30-60s, before sunscreen 10-15 minutes if going outdoors. Amount defaults: toner 5-8 drops, serum 2-3 drops or 1 pump, eye product ½ rice-grain per eye, gel moisturizer 1-1.5 peas, cream 1-2 peas, sunscreen 2-finger rule for the face. Retinoids go on fully dry skin, waiting 2-5 minutes before moisturizer if sensitive; if the routine pills, stings, or feels heavy, reduce layers, not increase them.

AM Maximum Stack: 1. Rinse/gentle cleanse (optional) → 2. pH-prep toner (optional) → 3. Hydrating toner layers (optional) → 4. Essence (optional) → 5. Mist (optional) → 6. Booster/soothing serum (optional) → 7. Antioxidant lane (optional) → 8. Pigment-support lane (this product can sit here if AM-tolerated) → 9. Hydration-serum lane (optional) → 10. Oil-control lane (optional) → 11. Peptide/repair lane (optional) → 12. Eye cream (optional) → 13. Moisturizer → 14. Occlusive seal (optional) → 15. Sunscreen SPF50+ PA++++ (non-negotiable) → 16. Lip SPF (optional).

In AM, prioritize comfort and SPF adherence over stacking. In high humidity, fewer layers often perform better.

PM Maximum Stack: 1. Micellar pre-cleanse (optional) → 2. Oil cleanser (if SPF/makeup worn) → 3. Water cleanser → 4. pH-prep toner (optional) → 5. Hydrating toner layers (optional) → 6. Essence (optional) → 7. Soothing/barrier serum (optional) → 8. Anchor active product (this serum sits here — apply on fully dry skin, wait 2-5 minutes if sensitive) → 9. Targeted serum (optional, non-conflicting only) → 10. Moisturizer → 11. Sleeping mask (optional) → 12. Occlusive seal (optional) → 13. Spot treatment/patch (as needed) → 14. Lip sleeping mask (optional).

Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night.

Lane strictness: one active lane per routine — this serum occupies the Retinoid lane; barrier/hydration products can always accompany. If unsure, default to the safest lane and reduce layers.

This is a light-fluid serum with suspended encapsulated beads — apply after any watery toner and before moisturizer. It is a water-phase formula; the Ammonium Acryloyldimethyltaurate/VP Copolymer and PVP in the ingredient list are the likely encapsulating polymer matrix that holds the trace Retinal stable in bead form until applied to skin.

Rest days: reviewers report no tingling even at nightly use, likely due to the trace retinal level, but starting at 3-4x/week for the first 2 weeks is still the safer default for anyone new to retinoid-labeled products. Overuse warning: exceeding nightly use does not produce faster brightening results — niacinamide and tranexamic acid both work on a gradual timeline regardless of how often you apply them beyond the recommended frequency.

Prerequisites: before starting this serum, your routine must already include a gentle cleanser, a basic moisturizer, and daily SPF.

Barrier index gate: if your skin stings on moisturizer, feels tight within 30 minutes of cleansing, or shows visible flaking, your barrier is below threshold — start with a plain barrier-repair moisturizer (e.g. Mighty Bamboo Panthenol Cream) first.

Primary targets: Post-inflammatory hyperpigmentation and dullness — tranexamic acid interrupts the plasmin-mediated signaling that triggers excess melanin production after inflammation, while niacinamide blocks the transfer of pigment granules (melanosomes) from melanocytes to surface skin cells. Secondary benefit: the Lactococcus Ferment Lysate (a postbiotic) and Ceramide NP offer supporting barrier reinforcement.

What this product cannot do: it cannot deliver meaningful retinoid-driven collagen stimulation or resurfacing at its trace Retinal concentration; it cannot lighten your natural skin tone — brightening here means fading excess pigment, not changing your baseline complexion.

All picks below are verified in Adilsons' live catalog with current stock, checked on 2026-09-10.

• Mighty Bamboo Panthenol Cleanser 150ml — low-pH cleanser that won't strip the barrier this serum's retinoid content depends on. Use before the serum, AM/PM.
• Oat-in Calming Gel Cream 100ml — lightweight barrier support to layer after this serum, especially useful if you notice any dryness.
• Daily Soft Touch Sunscreen 15ml — mandatory AM step given the retinoid content and active brightening pathway.

Pilling pairs: layering this serum under a heavy silicone-primer with no wait time can pill. Wait 1-2 minutes and use a lighter-textured moisturizer.

One Active Lane per routine: treat this serum as your Retinoid lane for the night, even though the retinal dose is trace — the product is still formulated and marketed around that lane.

× AHAs (Glycolic/Lactic/Mandelic/strong PHA): never the same night. Instead: skin cycling (Night 1 AHA → Night 2 this serum → Nights 3-4 recovery), or alternate nights.

× BHA (Salicylic Acid): avoid same night for most people. Instead: BHA on non-retinoid nights, or AM BHA / PM this serum.

× L-Ascorbic Acid (pure Vitamin C): don't layer in the same routine — split AM Vitamin C / PM this serum (a classic, well-tolerated split).

× Benzoyl Peroxide: do not layer — BPO can oxidize/deactivate retinoid-class ingredients. Instead: AM BPO / PM this serum, or a wash-off BPO cleanser.

Barrier override: if moisturizer stings or skin feels tight within 30 minutes of cleansing, pause this serum and run barrier-only care for 3-7 days before resuming.

Wait-time defaults: watery layers 10-20s, this serum 1-2 minutes, sunscreen 10-15 minutes before sun exposure.

Scheduling Template — AM/PM Split (most common): AM: Antioxidant lane (Vitamin C) → Moisturizer → SPF. PM: This serum (Retinoid lane) → Moisturizer.

Scheduling Template — 4-Night Skin Cycling: Night 1: Exfoliation lane. Night 2: This serum (Retinoid lane). Nights 3-4: Recovery, no actives.

Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night.

One-lane rule: Retinoid OR Exfoliation OR Strong Vitamin C (LAA) OR Acne-control active per routine; barrier/hydration can always accompany. If unsure, default to the safest lane — barrier/hydration — and reduce layers.

Permeability: Water-Permeable (wudu-compatible). This is a light, water-based serum without a heavy film-forming or occlusive finish, so water should reach the skin normally during ablution.

Adilsons provides this assessment based on the product's physical properties. Rulings on wudu validity vary between scholars. Consult your own trusted Islamic authority.

MYTH: "This serum will deliver full retinoid anti-aging results because it has 'Retinal' in the name." REALITY: Independent ingredient analysis puts the Retinal content at an estimated 25ppm — far below any concentration with published anti-aging evidence. The tranexamic acid and niacinamide are this formula's real, well-dosed active drivers.

MYTH: "You need to shake retinoid serums because the formula has separated / gone bad." REALITY: Shaking this specific serum is a required usage step because it suspends encapsulated retinal beads — it is by design, not a sign of spoilage.

Sugar cane burning season (July-November): PM2.5 rises during harvest burns; Tocopherol and Glutathione in this formula offer some supportive antioxidant defense, though SPF and cleansing remain the primary protections.

*Retinal at this estimated concentration sits far below the dose used in published retinaldehyde efficacy studies — its inclusion may be primarily for marketing/product-naming purposes rather than a meaningful independent anti-aging contribution at this dose.

Delivery system: the Retinal is encapsulated (suspended as beads using a polymer matrix — likely Ammonium Acryloyldimethyltaurate/VP Copolymer and PVP per third-party ingredient analysis) rather than freely dissolved in the serum. Shake before use to redisperse the beads; this improves stability and reduces direct-contact irritation, but does not increase the underlying concentration.

Full INCI: Water, Niacinamide, Tranexamic Acid, Glycerin, Caprylic/Capric Triglyceride, 1,2-Hexanediol, Methylpropanediol, Pentylene Glycol [--- Estimated 1% Line ---] PVP, Ammonium Acryloyldimethyltaurate/VP Copolymer, Butylene Glycol, Agar, Gellan Gum, Ethylhexylglycerin, Sodium Citrate, Hydroxyacetophenone, Citric Acid, Hydroxydecyl Ubiquinone, Adenosine, Lactococcus Ferment Lysate, Hydrogenated Lecithin, Centella Asiatica Extract, Ficus Carica (Fig) Fruit Extract, Fructooligosaccharides, Cyanocobalamin, Xanthan Gum, Retinal, Ceramide NP, Arginine, Tocopherol, Glutathione, Bisabolol, Helianthus Annuus (Sunflower) Seed Oil, Allantoin, Xanthophylls, Sodium Chloride, Phenylpropanol, Levulinic Acid, Sodium Levulinate.

This ingredient list is aggregated from third-party listings (INCIDecoder, whatsinmyjar.com, dermapproved.com) rather than a direct fetch of the brand's own page this session — treat as medium confidence pending a future direct-source re-check.

Preservative system: 1,2-Hexanediol, Ethylhexylglycerin, and Levulinic Acid/Sodium Levulinate — a fragrance-free, paraben-free multifunctional preservative system typical of modern K-beauty serums.

Fragrance status: Fragrance-Free — no Parfum/Fragrance ingredient in the declared INCI. Scent: No detectable added scent reported. Intensity: 0/5. EU 26 allergen screen: None detected in the declared INCI. Alcohol disclosure: Alcohol-Free — no denatured or drying alcohol in the ingredient list.

Ragweed allergy → Bisabolol: Bisabolol is most commonly derived from chamomile (or produced synthetically as alpha-bisabolol); individuals with a known ragweed/chamomile-family allergy should patch test before full-face use.

Prescription interaction: if you are currently using prescription tretinoin, adapalene, or isotretinoin, consult your dermatologist before combining with this product, even though its own retinal content is trace — layering two retinoid-labeled products can still create confusion about your actual total retinoid load.

Halal: Self-assessed by Adilsons based on available INCI data. No ethanol from fermentation, no porcine-derived ingredients, and no haram animal-derived ingredients detected in the declared ingredient list. This is NOT a formal Halal certification. Muslims with stricter requirements should consult their own scholars.

Vegan: Self-assessed by Adilsons based on available INCI data. No animal-derived ingredients detected. This is NOT a formal vegan certification by The Vegan Society or equivalent body.

Cruelty-Free: Brand-stated policy. Not independently certified by Leaping Bunny, PETA, or equivalent third-party audit. Purito does not appear on major independent cruelty-free trackers' certified lists and does not sell in Mainland China retail per our brand-level research.

Microplastic-Free: Yes — no polyethylene, acrylate copolymers of the microplastic-flagged type, or other flagged polymers detected in the declared INCI (the Ammonium Acryloyldimethyltaurate/VP Copolymer here is a water-soluble rheology/encapsulation polymer, not a microplastic-classified ingredient).

MFDS classification: General Cosmetic — no evidence found of a Functional Cosmetic registration for this SKU. Whitening translation: the Korean "미백" (mibaek) classification, where it applies, means regulation of melanin production — fading dark spots to reveal your natural tone, not bleaching. Evidence confidence: High for tranexamic acid and niacinamide's pigment-fading mechanisms (well-established at the category level); Marketing-Only* for the Retinal's anti-aging contribution at its estimated trace concentration. We found a reference in aggregated search results to a "Korea Institute of Dermatological Sciences" clinical study for a Purito retinal serum, but could not trace it to a real, citable source — it is deliberately NOT repeated as fact here.

*Retinal's published anti-aging evidence base applies at concentrations far above the estimated 25ppm in this formula.

Fungal Acne Safety: FA-Conditional. Hydrogenated Lecithin appears in the mid-list — flagged as conditional (not universally unsafe) by community fungal-acne-safety trackers; likely present at low concentration given its position, but patch test if you're highly FA-reactive.

Assessment: Low-to-Medium. Can pill under a heavy silicone-primer or thick occlusive with no wait time. Mitigation: shake before use, wait 1-2 minutes, use a lighter moisturizer, and pat rather than rub.

Fresh product should show visible fine beads (encapsulated retinal) that redisperse evenly when shaken — this is normal, not spoilage. Storage: keep out of direct sun and heat, since retinoid-class ingredients degrade faster with light and heat exposure even at low concentrations. Spoilage signs: beads that clump and won't redisperse, a sour smell, or a significant color shift beyond the normal faint pink tint. When in doubt, discard.

Patch test: inner forearm, wait 24 hours; if clear, apply behind the ear, wait another 24 hours; then begin facial use.

72-hour barrier reset (if you react): stop all actives. For 72 hours, use only a gentle cleanser, a plain moisturizer, and mineral SPF — no acids, retinoids, Vitamin C, exfoliants, or essential oils. After 72 hours, reintroduce one product per 14 days.

Emergency stop signals: hives, swelling, blistering, persistent burning, or breathing difficulty — seek emergency care immediately.

Pregnancy alternatives: if you are pregnant or nursing, verified in-catalog brightening options without retinoids include Purito Azelaic Acid 10 Kojic Tea Tree Serum (azelaic acid is broadly considered pregnancy-compatible under medical guidance — confirm with your own doctor) and Anua Niacinamide 10%+TXA 4% Serum (no retinoid at all).

1. Skipping the shake step and applying an uneven dose of the settled beads. 2. Expecting strong retinoid resurfacing from a trace-dose ingredient. 3. Using it as an AM product without reinforcing SPF. 4. Layering with a separate strong AHA/BHA or another retinoid the same night. 5. Purchasing while pregnant or nursing without checking the safety notice above.

Overuse threshold: more than once nightly provides no additional benefit.

Usage math: at roughly 0.5ml per application (2-3 drops), a 30ml bottle provides approximately 60 applications. Lifespan: at 3-4 uses per week, that's roughly 4-5 months of use; nightly use from day one cuts that to about 2 months. Reorder timing: plan to reorder about 2 weeks before you expect to run out — though note this SKU is currently out of stock; check availability before planning around it.

This serum is your evening brightening/retinoid-lane step — it belongs after cleansing and toning, before moisturizer.

PM (recommended primary slot): 1. Double cleanse if wearing SPF/makeup → 2. Toner (optional) → 3. TXA 6 Niacinamide 10 Retinal Serum (shake first), 2-3 drops, wait 1-2 minutes → 4. Moisturizer. AM (only if tolerated): same order, followed by mandatory sunscreen.

If your skin is barrier-compromised right now: hold off and repair with plain moisturizer for 1-2 weeks first (Sec 12). If you are pregnant or nursing: do not use this product — see the pregnancy alternatives in Sec 33. If you are also using a separate exfoliating acid: alternate nights rather than combining both.

Stock-true bundle — Brightening Support: Mighty Bamboo Panthenol Cleanser → this serum → Oat-in Calming Gel Cream → Daily Soft Touch Sunscreen. Why: a low-irritant cleanser and calming cream buffer the retinoid-lane serum, and SPF protects the pigment being treated.

The recommendations above are based on formulation synergy with TXA 6 Niacinamide 10 Retinal Serum, not on margin or stock levels. If a pairing does not exist in our catalog, we say so. If you already own a product that fills the same role, use what you have first.

Anua Niacinamide 10%+TXA 4% Dark Spot Correcting Serum 30ml matches this product's niacinamide concentration with a slightly lower 4% tranexamic acid and no retinoid at all — a better fit for pregnant/nursing customers or anyone who wants a brightening serum with zero retinoid content, currently well-stocked.

If you specifically want a real retinoid dose rather than a trace one, Purito Retinol Retinal 2000 NAD+ Serum 30ml (same brand) is formulated around meaningfully higher retinoid content — a genuinely different, stronger product rather than a like-for-like swap.

Choose TXA 6 Niacinamide 10 Retinal Serum over Anua Niacinamide 10%+TXA 4% Serum if you need a higher 6% tranexamic acid dose specifically: this formula's TXA concentration is 2 percentage points higher, which may matter for more stubborn pigmentation, though the retinal content itself is not a meaningful differentiator at its trace dose.

Upgrade triggers: If you specifically want a slightly higher TXA percentage and are not pregnant/nursing — choose this Purito formula. If you are pregnant, nursing, or want zero retinoid exposure for any reason — choose the Anua alternative instead. If you want genuine retinoid strength — neither of these is the right product; see the Retinol Retinal 2000 NAD+ Serum instead.

Don't upgrade to this over the Anua alternative if: you are pregnant, nursing, or specifically want to avoid retinoid-labeled products regardless of stated concentration.

If you match the higher-TXA trigger above and are not pregnant/nursing, this product is worth choosing. If a retinoid-free formula matters to you, the Anua version is the safer, equally valid choice. Consistency beats complexity.

This product's PRIMARY function is: pigment/tone brightening via tranexamic acid and niacinamide. You do NOT need this if you already own a well-tolerated TXA and/or niacinamide brightening serum from any brand — finish that one first.

Stacking assessment: No Benefit if run alongside another niacinamide+TXA product (same mechanism). Marginal Benefit if paired with azelaic acid (overlapping pigment pathway, some added benefit). Significant Benefit if it replaces a harsher, higher-strength retinoid you're not currently tolerating well — though note this product is not a true substitute for real retinoid strength given its trace dose.

Founded: 2017 · Headquarters: Incheon, South Korea · Hero ingredient: Centella Asiatica (Wonder Releaf line) · Philosophy: minimal, "clean beauty" formulas emphasizing gentle, sensitive-skin-friendly, often fragrance-free options.

This serum sits within Purito Seoul's expansion into clinical-active, targeted-concern serums (alongside its Vitamin C and Azelaic Acid/Kojic/Tea Tree formulas), pairing well-dosed brightening actives with a small, name-recognizable retinoid inclusion — a common industry pattern where the headline ingredient in a product's name is not always its primary functional driver.

Independent review aggregation (DermApproved, whatsinmyjar.com, arktastic.com) consistently describes this serum as unusually gentle for a retinoid-labeled product, with one reviewer calling it the most gentle niacinamide serum they'd tested, and no reports of tingling or purging turned up in this pass. Ingredient-focused reviewers repeatedly flag the Retinal content as a trace amount well below a functional dose, framing the real value of the product as its 6% tranexamic acid and 10% niacinamide combination. We did not find a specific Reddit r/AsianBeauty or r/SkincareAddiction thread for this exact SKU, and could not verify a specific clinical-study citation mentioned in one AI-generated search summary — that claim is not repeated here as fact.

Why do I need to shake the bottle? This formula suspends encapsulated retinal beads that can settle over time — shaking redisperses them for an even dose. It is a required step, not an optional tip.

Is this a strong retinoid product? No — the Retinal content is estimated at ~25ppm, a trace amount. This serum's real, well-dosed actives are 6% tranexamic acid and 10% niacinamide.

Can I use this while pregnant? No — it contains a retinoid (Retinal) regardless of concentration. See the safety notice above for verified retinoid-free alternatives.

Will it help with acne scarring? It helps fade pigment (PIH) left behind by acne, not depressed/textural scarring, which needs a different treatment approach entirely.

Is it currently in stock? No — this SKU shows 0 units in our live inventory at the time of writing; check back or contact us on WhatsApp for restock updates.

Tranexamic Acid (TXA)

A synthetic amino-acid derivative that reduces pigment production by interrupting inflammatory signaling to melanocytes.

Retinal (Retinaldehyde)

A Vitamin A derivative one conversion step closer to active retinoic acid than retinol; generally considered faster-acting but also used at much lower concentrations.

Encapsulation

Suspending an active ingredient inside a polymer shell/bead to improve stability and reduce direct-contact irritation.

Postbiotic

A beneficial metabolite from fermentation (not a live microorganism) — Lactococcus Ferment Lysate in this formula is one example.

PIH

Post-inflammatory hyperpigmentation — brown/tan marks left after skin inflammation, caused by excess melanin.

Fairy Dusting

Including a trendy ingredient at such a low concentration that it functions mainly as a marketing signal rather than an active treatment.

Best for: non-pregnant, non-nursing customers with dullness or post-acne pigmentation who want a well-dosed 6% tranexamic acid + 10% niacinamide brightening serum, and don't mind that the retinal content is essentially symbolic.

Key benefits: genuinely potent TXA and niacinamide concentrations; fragrance-free; unusually gentle per aggregated reviews; postbiotic barrier support.

Keep in mind: the Retinal is trace-level and should not be the reason you buy this; it is contraindicated in pregnancy/nursing regardless of that trace dose; it is currently out of stock in our catalog.

Assessment: Consult Oncologist. This formula is fragrance-free, but it contains a retinoid (Retinal), and retinoid-class ingredients are commonly flagged as needing oncology-team clearance during active cancer treatment regardless of concentration.

Consult your oncology care team before introducing any new skincare products during treatment.

Quick version: Week 1-2 — introduce alone, 3-4x/week, monitor for any irritation (uncommon given the trace retinal dose, but still worth watching). Week 3-4 — increase to nightly if stable. Week 5+ — add one supporting product only if truly needed. If irritation occurs, use the 72-Hour Barrier Reset (Sec 33) rather than pushing through.

This product must be introduced as the ONLY new product. Wait 14 days before adding anything else.

Retinization note: because the retinal dose here is trace, classic retinization side effects (peeling, redness) are uncommon — but if they do occur, reducing frequency rather than stopping entirely is still the correct response.

Impact: Supportive. This formula contains Lactococcus Ferment Lysate, a postbiotic — beneficial metabolites from fermentation. You are not applying live bacteria. Combined with Ceramide NP, this supports rather than disrupts the skin's barrier and microbiome balance.
