The Anua Niacinamide 10% + TXA 4% Serum targets dark spots, hyperpigmentation, and uneven skin tone in adult skin. On Flash AI, it earns an AI Score of 90/100, drawn from 6220 verified reviews across 5 platforms, with effectiveness rated at a perfect 100 and texture at 94. The formula slots into daily morning and evening routines, and its lightweight, fragrance-free composition makes it a low-irritation option for most skin types.
Four active ingredients drive the formula. Niacinamide at 10% targets dark spots and hyperpigmentation while supporting the skin barrier. Tranexamic acid at 4% addresses discoloration including melasma and acne scars, working together with niacinamide and alpha-arbutin to reduce uneven tone and improve skin clarity. Alpha-arbutin adds further brightening action. Hyaluronic acid rounds out the formula with hydration, leaving skin with a smooth, dewy finish. The product holds vegan and cruelty-free certifications, carries no added fragrance, and features a fast-absorbing texture that needs no refrigeration.
Verified reviewer feedback confirms this serum works well across sensitive, acne-prone, dry, oily, and combination skin types. Those targeting post-inflammatory hyperpigmentation, melasma, or acne scars will find the four-active combination directly relevant. That said, the 10% niacinamide concentration has caused stinging or dryness for some individuals with very sensitive skin, so patch testing before full application is advisable, and starting with fewer applications per week suits first-time users better. Layering this serum with vitamin C, AHAs, BHAs, or retinol at the same time has increased sensitivity for some users, making it safer to separate strong actives across morning and evening routines. Some acne-prone users have also reported pore clogging or breakouts, and oily skin types may find the texture sticky in hot or humid conditions.
The Anua Niacinamide 10% + TXA 4% Serum is available from 14 sellers in India, with prices ranging from ₹583 to ₹5779. That spread reflects significant variation between sellers, so verifying listings before purchasing is worthwhile. At ₹583, the serum delivers a strong price-to-ingredient ratio for a four-active brightening formula. Reviewers consistently associate visible improvements in dark spots and skin radiance with several weeks of continued use. Flash AI recommends this serum for adults seeking a fragrance-free, targeted treatment for hyperpigmentation, with the caveat that very sensitive skin types should introduce it gradually and avoid simultaneous use with strong actives.

The serum is designed for daily use, both morning and evening. Apply a few drops to affected areas and gently pat in with your fingertips. If your skin is new to niacinamide at this concentration, gradually increase the frequency of use rather than jumping straight to twice-daily application.
The serum is formulated for all skin types, including sensitive, acne-prone, dry, oily, and combination skin. Reviewer feedback broadly supports this range. Oily skin types may notice some stickiness in hot or humid weather, and very sensitive skin types should patch test first before incorporating it into a full routine.
Tranexamic acid at 4% works to reduce discoloration including melasma and acne scars. Paired with niacinamide at 10% and alpha-arbutin, the three ingredients address uneven skin tone from multiple angles. Reviewer insights note significant improvements in dark spots and skin clarity with consistent use of this combination.
Reviewer feedback links meaningful improvement in dark spots and skin radiance to several weeks of consistent use. Results vary by skin type and the severity of hyperpigmentation. Reviewers who maintained use for four or more weeks reported the clearest changes in dark spots and overall skin tone.
Yes, the 10% niacinamide concentration has caused stinging or dryness for some individuals with very sensitive skin. The product carries a low-irritation highlight and contains no added fragrance, but patch testing on a small area before full application is recommended. Starting with fewer applications per week and building up gradually is the safer approach.
A basic niacinamide serum typically contains niacinamide as its sole active ingredient. This formula combines four actives: niacinamide at 10%, tranexamic acid at 4%, alpha-arbutin, and hyaluronic acid. That combination addresses hyperpigmentation from multiple pathways while also providing hydration, which a single-active niacinamide serum would not do on its own.
The serum is listed across 14 sellers in India, with prices starting from ₹583. To secure the lowest price, compare listings across major Indian retail platforms and confirm the seller has a verified badge before purchasing to ensure product authenticity.
The serum has a lightweight, bouncy texture that absorbs into skin without stickiness or greasiness for most users, leaving a smooth, dewy finish. Oily skin types may notice some stickiness in hot or humid weather. A subset of reviewers noted the serum can leave a layer that flakes when a cream is applied directly on top.
For most skin types, niacinamide at 10% is well-tolerated with daily use, and broad reviewer feedback supports this. The product is intended for morning and evening application. Individuals with very sensitive skin have experienced stinging or dryness at this concentration, so patch testing and gradual introduction are the recommended starting points.
Negative reviewer insights indicate that combining this serum with strong actives such as vitamin C, AHAs, BHAs, or retinol at the same time can increase sensitivity and cause irritation. Separating these actives across your morning and evening routine rather than layering them simultaneously is the recommended approach. Patch testing any new combination before full application is also advisable.
