La Roche-Posay Effaclar Duo+M Anti-Blemish Patches are designed for acne-prone skin to visibly reduce the size and redness of spots while helping them clear up in as little as 3 hours. Featuring hydrocolloid technology, they create a protective barrier that absorbs impurities and helps maintain skin hydration. Ultra-thin and easy to remove, the patches provide discreet protection against contact with blemishes and come in two sizes to suit different areas of the face.
