La Roche-Posay Effaclar Serum is a 30ml concentrated formula designed for oily skin. This lightweight, non-greasy serum is formulated with LHA, salicylic acid, zinc PCA, glycerin, and La Roche-Posay thermal spring water. These ingredients work together to deeply cleanse, refine the appearance of pores, improve skin texture, and regulate oil production to reduce shine. The serum is fragrance-free, paraben-free, and mineral oil-free. It is dermatologically tested and non-comedogenic, making it suitable for sensitive skin. To use, apply a small amount to clean, dry skin in the morning and evening, avoiding the eye and lip areas. This product aims to provide a clearer, smoother complexion by gently exfoliating dead skin cells and minimizing the appearance of blemishes while maintaining hydration and soothing the skin to prevent irritation and dryness.
