Description
La Roche-Posay Effaclar Mask 100ML is a purifying clay mask designed to deeply cleanse pores, absorb excess oil, and help reduce the appearance of blackheads and shine. It is suitable for oily, combination, and acne-prone skin, especially skin prone to clogged pores and uneven texture.
The formula typically contains absorbent clays (such as kaolin) combined with soothing ingredients like La Roche-Posay thermal spring water, helping to purify the skin while maintaining comfort and reducing irritation. It works to refine pores, mattify the skin, and improve overall clarity without over-drying.
Apply a thin layer to clean, dry skin, avoiding the eye and lip areas. Leave on for about 5–10 minutes, then rinse thoroughly with water. Use 1–2 times per week depending on skin needs.
With consistent use, skin appears clearer, smoother, and less oily with reduced shine, refined pores, and a more balanced, refreshed complexion.
