La Roche-Posay Effaclar Purifying Cleansing Gel contains soothing and anti-irritating La Roche-Posay Thermal Spring Water. Effaclar is a complete skincare solution adapted for all types of imperfection-prone skin. Naturally hyperactive sebaceous glands produce an excess amount of sebum, causing the skin to become shiny. Environmental variations can cause sebum to oxidize, stimulating sebaceous glands further and leading to blocked pores and imperfections. This non-comedogenic gel features optimum concentrations of dermatological active ingredients in simplified formulas for purity and tolerance. Its packaging is especially designed to minimize bacterial contamination.
