CeraVe Blemish Barrier Patches are thin hydrocolloid patches with tapered edges, supplied in two sizes. From the first use they reduce the appearance of blemishes and redness, absorb excess oil and help prevent picking, to reduce the risk of post-blemish marks. They contain 3 essential ceramides and niacinamide to help protect the skin barrier. They are suitable for sensitive skin and are fragrance-free, paraben-free and allergy-tested.
