ANUA Niacinamide 10% + TXA 4% — Sérum Correcteur Anti-Taches

This serum builds its strength on precise dosing: three anti-spot molecules work in sequence to slow melanin without causing irritation.

Niacinamide 10% (Nicotinamide)
This water-soluble vitamin B3 acts on several levels: it inhibits the transfer of melanosomes to keratinocytes (thus limiting pigment rise to the surface), strengthens ceramide synthesis in the skin barrier, and regulates sebum secretion. At 10%, the concentration is high enough to observe a smoothing effect on skin texture and a gradual fading of spots.

Tranexamic Acid 4% (Tranexamic Acid)
Less known than its cousin vitamin C, TXA acts upstream in the inflammatory cascade: it blocks the arachidonic acid pathway and thus reduces post-inflammatory hyperpigmentation. Ideal after a pimple or irritation that has left a brown mark.

Arbutin 2% (Arbutin + Alpha-Arbutin)
Naturally extracted from bearberry (or uva-ursi) leaves, arbutin rivals hydroquinone in gentleness: it limits the activity of tyrosinase, the key enzyme in melanin synthesis, without the feared rebound effects of harsh depigmenting agents.

3-O-Ethyl Ascorbic Acid
A stable, lipophilic derivative of vitamin C that penetrates the epidermis better than pure ascorbic acid. It boosts collagen production and protects against daily oxidative stress (UV, pollution).

Ceramide NP + Hyaluronic Acid (3 molecular weights)
To prevent this active blend from drying out the skin: the hyaluronic trio (Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid) maintains hydration on the surface and deep within, while Ceramide NP strengthens intercellular junctions.

☀️ Morning routine

1. Gentle cleansing (low-pH gel or foam)
2. Balancing lotion
3. 2-3 drops of ANUA Niacinamide 10% + TXA 4% serum, tapped over the entire face or locally on pigmented areas
4. Light moisturizer
5. SPF 30 minimum (TXA and niacinamide make the skin more sensitive to the sun during the first few weeks)

🌙 Evening routine

1. Double cleansing (oil then gel)
2. Lotion
3. 2-3 drops of serum (you can increase to 4-5 if your skin tolerates it well)
4. Night cream or sleeping mask

Layering tip: If you use retinol, apply the ANUA serum first, wait 5 minutes, then apply your retinol. Niacinamide buffers potential retinol irritation.

Frequency: Start with 3 nights a week, then move to daily morning and evening once your epidermis has adjusted (usually after 7-10 days).

• Skin with post-acne hyperpigmentation : if your pimples leave brown spots that take months to fade, this TXA + niacinamide + arbutin trio specifically targets this residual melanin.
• Combination to oily skin prone to enlarged pores : 10% niacinamide regulates sebum and visually tightens pores (effect noticed after 4 weeks of continuous use).
• Dull, tired complexions marked by the sun : for those who want to regain an even glow without resorting to harsh chemical peels.
• Users of retinol looking for a complementary serum : niacinamide soothes and strengthens the barrier, which limits retinol peeling.
• Fans of serums with a watery texture : if you hate sticky sensations, this one absorbs in 15 seconds.

Avoid if:

• Your skin is in an acute inflammatory crisis (active cystic acne flare-up): wait for the lesions to calm down before introducing anti-spot actives.
• You react badly to high doses of niacinamide: some skins flush starting at 5-10% (rare, but it happens). Do a patch test on the jaw 48 hours before.

From 2 weeks: Refined skin texture, less visible pores upon waking, more even complexion (especially in the T-zone). The watery texture absorbs quickly, without a greasy film — perfect under makeup.

After 4 weeks: Post-inflammatory spots (red/brown marks left by pimples) begin to fade. TXA and arbutin slow down the production of new melanin, so future marks will be less persistent.

After 8 weeks: Visible reduction of established spots (mild melasma, solar lentigines). Overall skin radiance improves thanks to the synergy of niacinamide + vitamin C derivative. The skin barrier is stronger (less reactive redness).

Long-term use: Prevention of new spots if combined with rigorous sun protection. Niacinamide continues to regulate sebum and maintain the hydrolipidic balance, making this serum as beneficial for maintenance as for correction.

Can I use this serum every day, morning and evening?

Yes, but start gradually. Apply it every other evening during the first week to let your skin get used to the 10% niacinamide. If no redness or tightness appears, move to daily use morning and evening. In the morning, SPF 30+ is non-negotiable: TXA and arbutin temporarily increase photosensitivity.

Does this serum work on active acne or only on marks?

It primarily targets post-inflammatory hyperpigmentation, not active pimples. If you have active acne, first treat with a BHA (salicylic acid) or benzoyl peroxide, then use the ANUA serum to fade marks once lesions have healed. TXA helps prevent these marks from becoming permanent.

Can I combine it with retinol in the same routine?

Absolutely — it’s even recommended. Apply the niacinamide serum first (it soothes irritation), wait 5 minutes for it to absorb, then apply your retinol. Niacinamide strengthens the skin barrier and reduces redness often caused by retinol, especially during the adjustment phase.

How long does a 30 ml bottle last?

About 2 months if you use 2-3 drops morning and evening (about 1 ml per day). The liquid texture is easy to dose with the dropper: no need to use more, excess won’t absorb better.

Why does the serum have a natural yellowish color?

It’s the natural shade of niacinamide and the vitamin C derivative (3-O-Ethyl Ascorbic Acid). No artificial coloring is added. If the color turns dark brown or the smell becomes rancid, the product has oxidized: keep it away from direct light and close the cap tightly after use.

Can I use it if I have sensitive skin or rosacea?

10% niacinamide is generally well tolerated, even by reactive skin (it soothes inflammation). But if you are very sensitive, do a patch test on a small area for 48 hours. In case of severe rosacea, consult your dermatologist first: TXA is gentle, but every skin reacts differently to high concentrations of active ingredients.

ANUA (a contraction of "A" + "Natural") was born in 2019 in South Korea with a conviction: healthy skin depends not only on the products applied but on overall balance — a calm mind, regulated lifestyle, pure ingredients. The brand positions itself in minimalist clean beauty: short formulas (often fewer than 20 ingredients), natural or organic actives when possible, zero parabens, zero synthetic fragrance, simple packaging.

The historic bestseller? The Heartleaf 77% Soothing Toner, voted No. 1 at the Olive Young Awards 2022. But ANUA is not limited to heartleaf (houttuynia cordata): the Niacinamide 10% + TXA 4% range, launched in 2023, meets a growing demand for scientifically dosed, effective anti-spot serums without a prescription. The niacinamide-TXA-arbutin trio follows clinical dermocosmetic codes while remaining accessible and "skin-first."

All ANUA products are 100% made in South Korea, with rigorous ingredient sourcing (favoring Korean botanical extracts: heartleaf, mugwort, green tea). The brand is cruelty-free, and most formulas are vegan (a few exceptions with ferments or animal derivatives, always indicated).
