Uriage Hyséac SOS Paste is an overnight spot treatment designed to accelerate the healing of blemishes on oily, acne-prone skin. Its formula combines purifying shale extract, absorbent green clay, and zinc to act on imperfections as you sleep. Enriched with Uriage Thermal Water, this paste also soothes the skin locally, reducing irritation. The non-comedogenic and fragrance-free treatment works from the first night to mature spots, helping them to disappear more quickly. For best results, apply directly onto a blemish in the evening, leave on overnight, and rinse off in the morning.
