La Roche Posay Effaclar Duo+M Patch is a clinically proven product that helps to visibly reduce the appearance of spots in as little as 3 hours. It's ideal for daytime spot treatment or as an overnight remedy. Each pack includes 12 small and 10 medium-sized patches. The product has triple-action performance: it protects the skin from picking and environmental aggressors, targets early-stage and raised spots, and clears impurities directly into the patch. The 420µM hydrocolloid technology ensures easy application and removal while supporting skin recovery. The patch helps prevent picking and post-blemish marks. According to a clinical study of 64 participants, 96% reported reduced spot visibility and 94% noticed spots faded quickly.
