Scars can be caused by any type of skin injury or wound. Ideally, a scar is smooth, flat, and blends in with surrounding skin, but sometimes very visible, unattractive scars can appear. Nothing can make scars totally disappear, and nothing can hurry the natural healing process (MEDERMA is not intended for open wounds). However, MEDERMA Skin Care for Scars helps scars appear softer and smoother.
