How to choose its serum

A few guidelines: aim for a concentration of 2 to 5 % of tranexamic acid (beyond this, more irritation with no guaranteed benefit). Choose formulas that combine it with niacinamide or a vitamin C derivative, for enhanced anti-spot action. For oily or blemish-prone skin, prefer a light, watery texture; for dry skin, a more emollient texture. For sensitive skin, check the Sensitivity Verdict and introduce the product gradually.

The SPF, non-negotiable

Tranexamic acid is not photosensitizing, but SPF 50 sun protection every morning remains essential: the sun is the leading cause of hyperpigmentation and would ruin the serum's efforts.

Your questions about the choice

What is the best tranexamic acid serum?
There's no single winner: it all depends on your skin. Anua Niacinamide 10 % + TXA 4 % offers excellent value for money and is suitable for sensitive skin; Nooance Soin Clarifiant is the most complete on spots and redness; Vichy Liftactiv Sérum B3 is the easy-to-find parapharmacy option.
Tranexamic acid or vitamin C for spots?
Both are effective and complementary. Vitamin C is an antioxidant that brightens and protects, while tranexamic acid targets melasma and redness more specifically, and is less irritating. Many anti-spot routines combine the two: vitamin C in the morning and tranexamic acid in the evening, for example.
How long does it take to see results?
In general, 8 to 12 weeks of regular use are required for visible improvement in dark spots, under strict sun protection. Studies on melasma show effects from 8 weeks onwards. Patience and regularity are essential for pigmentary disorders.

Information for educational purposes only. It does not replace a medical consultation and must be adapted to each individual. The compatibility scores generated by the application do not prejudge the individual tolerance of each skin type. Tranexamic acid is well tolerated and non-photosensitizing, but above the recommended doses (2 to 5 %) irritation may occur: a gradual introduction is recommended for sensitive skin. Daily SPF 50 sun protection remains essential. In cases of melasma, rosacea or other skin disorders, dermatological advice is recommended. A tolerance test should be carried out before using the product for the first time.
