Age spots, sun spots, and other pigmentation changes can make skin tone less even and luminous, especially with accumulated sun exposure over time. La Roche-Posay Mela B3 Double Dose 40 ml is an intensive facial treatment for day and night use, developed to address hyperpigmentation and some signs associated with skin aging. Its formula combines Melasyl™, a molecule developed by La Roche-Posay to act on the formation of hyperpigmentation, with Proxylane, an ingredient that helps improve the appearance of firmness, elasticity, and hydration of the skin, and niacinamide, known for its role in maintaining the skin barrier and evening out skin tone. The formula has an emulsion texture that melts into the skin and is suitable for all skin types, including sensitive skin. A clinical study conducted on 42 individuals observed a 30% reduction in the intensity of a persistent spot after 12 weeks of twice-daily use, while instrumental measurements after a single application indicated a 20% increase in firmness.
