La Roche-Posay Effaclar Ultra Concentrated Serum is a specialized skincare treatment designed to target imperfections, reduce marks, and provide daily peeling action. This advanced formula helps improve skin texture and clarity through its concentrated blend of active ingredients. This serum contains key active ingredients like Salicylic Acid, LHA, and Niacinamide that work together to unclog pores and control excess oil. The lightweight, non-greasy texture absorbs quickly into the skin. It is suitable for acne-prone and sensitive skin types, being both allergy-tested and free from parabens, soap, and oils. For best results, apply in the evening as part of your skincare routine.
