Description Erborian Centella SOS Anti-Imperfection Patch 9ml is a gel-effect anti-blemish patch. This targeted treatment, combining niacinamide and 10% PHA, a gentle exfoliating acid, visibly reduces the appearance and size of blemishes for skin that looks smoother and more even. Enriched with Centella Asiatica, the formula works gently without drying out the skin. Like a second skin patch, it forms a transparent and smoothing protective film, allowing for easy makeup application. Tested under dermatological control.
