50 million Americans suffer from acne every year, and anyone who does knows about nasty scars acne can leave. Often times, these marks last way longer than the actual blemish itself and can be harder to treat. "Scars can be divided into two [categories] – dark marks that are actually a result of post-inflammatory hyperpigmentation, and the other type which involves a change in skin texture resulting in depressed or raised scars," explains Dendy Engelman, MD, a dermatologist in New York City.
Dark mark scars crop up generally as superficial pink, red, or brown marks. Dr. Engelman suggests looking for salicylic acid or glycolic acid peels that will help promote cellular turnover to remove the top layers of the skin. This hyperpigmentation, can be faded with brightening ingredients like hydroquinone, kojic acid, phytic acid, and l-asorbic acid," she says, or LED or photodynamic light therapy can also help fade the mark.
Texture scars, which are raised or sunken marks on the skin, can be treated with microneedling, dermaroller, fractionated Co2, and deep chemical peels, which actually slightly damage skin to help promote collagen production and fill scars from within, says Dr. Engelman.
"Post inflammatory hyperpigmentation (PIH) can persist for weeks to months and is often more problematic than the underlying acne itself," says Valerie Harvey, MD, a dermatologist in Virginia. "Treating the underlying acne early and effectively is important in the prevention of PIH, and options include topical lightening creams that include ingredients such as hydroquinone, tranezamic acid, niacinamide, and kojic acid, or chemical peels."
