Description

Intensive dark spot treatment. Clinically proven. Anti-recurrence.

Introducing the La Roche-Posay Mela B3 Serum — the most advanced dark spot and hyperpigmentation treatment from La Roche-Posay, formulated with the brand's exclusive Melasyl™ technology — a clinically proven brightening molecule that targets persistent dark spots and post-imperfection marks at the source — combined with an impressive 10% Niacinamide (Vitamin B3) for comprehensive brightening and tone-evening.

Melasyl™ is La Roche-Posay's proprietary ingredient specifically developed and clinically tested on skin types with a tendency to develop dark spots — including post-acne marks, melasma and sun-induced hyperpigmentation. It works at the melanin synthesis level — blocking the production of excess pigment while the 10% Niacinamide brightens, evens tone and supports barrier health. The anti-recurrence formula ensures that dark spots are not only faded but prevented from returning — a truly complete approach to lasting pigmentation correction.
