This La Roche-Posay Mela B3 Serum is a 50ml dark spot corrector formulated to target the look of stubborn dark spots, post-acne marks, and uneven skin tone. Formulated with 10% Niacinamide, it works to visibly reduce the appearance of discoloration while strengthening the skin barrier. The lightweight, liquid-based serum texture absorbs quickly to deliver active ingredients without leaving a greasy residue. You should use this serum if your primary concern involves pigmentation issues such as sunspots, post-inflammatory hyperpigmentation (PIH), or melasma, as it is designed to interrupt the melanin production cycle. It is also ideal for those with dry or dehydrated skin who experience tightness and flakiness, as the formula helps to improve skin radiance without causing additional dryness. This product is suitable for sensitive skin types and can be incorporated into both morning and evening routines.
