Melasma is a common skin condition that causes brown patches to appear on the face. It is often caused by excessive sun exposure, hormonal changes, or certain medications.
La Roche-Posay Rétinol B3 is an anti-aging serum that contains retinol and niacinamide. Retinol is an active ingredient that helps reduce the appearance of wrinkles and fine lines, while niacinamide helps brighten the skin and reduce the appearance of brown spots.
How does La Roche-Posay Rétinol B3 work?
Retinol is a derivative of vitamin A that works by stimulating the production of collagen and elastin. Collagen and elastin are proteins that give the skin its structure and elasticity. By stimulating their production, retinol helps reduce the appearance of wrinkles and fine lines.
Niacinamide, on the other hand, is a B vitamin that helps brighten the skin and reduce the appearance of brown spots. It works by inhibiting the production of melanin, the pigment that gives the skin its color.
