Niacinamide 10 Serum

Visible pores, uneven skin tone, and lingering post-acne marks: this serum tackles all three simultaneously.

10% Niacinamide (40ml) regulates sebum production and evens out skin tone by limiting melanin transfer to the surface. Tranexamic acid targets hyperpigmentation by blocking melanin synthesis at its source, while succinic acid tightens pores and reduces imperfections. Squalane and hyaluronic acid complete the formula to maintain hydration without feeling heavy.

Result: smoother, brighter skin with less visible pores in just a few weeks. Ideal for combination to oily and acne-prone sensitive skin.

Apply a few drops morning and eveningafter toner, before moisturizer. The watery texture absorbs quickly — no need to wait before moving on to the next steps. In the evening, you can layer it under a repairing active. In the morning, be sure to pair it with SPF: without sun protection, tranexamic acid and niacinamide will not be able to prevent the reformation of spots.

Can niacinamide be used every day?

Yes. Niacinamide is one of the best-tolerated active ingredients, even for sensitive skin. This serum can be used morning and night without interruption. If you have very reactive skin, start by applying it only in the evening for two weeks before switching to a twice-a-day regimen.

What should you not mix with niacinamide?

Niacinamide combines well with most active ingredients: hyaluronic acid, retinol, peptides, and ceramides.

Alternate morning/evening or use stabilized formulas. With AHAs/BHAs, apply the exfoliants first and let them sit for a few minutes.
