Options for removing acne scars include laser resurfacing, fractional laser therapy and dermabrasion. Using lotions and face masks to treat acne scars can cause the skin to become irritated and the scars to become even more prominent.
A dermatologist might inject the skin with a material to smooth out rolling scars. For acne scars that are worn deep into the skin, a dermatologist may recommend surgery.
Red and brown spots that are left over from recent pimples usually fade after a year or so. It is best to speak with a dermatologist if the marks remain after that length of time.
