La Roche-Posay

Effaclar Ultra Concentrated Serum

This ultra-concentrated serum targets imperfections, excess sebum, and fine lines using a potent blend of salicylic, glycolic, and lipo-hydroxy acids. The formula deeply unclogs pores and stimulates cell renewal while niacinamide strengthens the skin barrier to prevent moisture loss. Enriched with thermal spring water, it effectively soothes the complexion and reduces irritation for a smoother, clearer appearance.
