There are many different types of acne scars: there are atrophic (or pitted) scars, which can affect the texture of the skin, and there are erythematous or hyperpigmented scars, such appear as spot on the skin but do not change the skin’s texture. Thankfully, there are treatments available for both types of acne scarring. While fractional resurfacing lasers, such as the Fraxel and Fractional CO2 laser, are the best treatments for treating atrophic acne scars, the KTP laser can treat acne scars that appear as red marks on the skin.
Dr. Schweiger explains that, “After an inflammatory acne bump resolves, it often leaves something called post-inflammatory erythema behind on the skin. This phenomenon appears as a reddish mark at the same site as the original acne lesion. Time and some topical medications can help to lighten these spots, but only a vascular laser can truly remove the red marks left behind from acne.”
The KTP laser can treat acne scars by breaking up the collections of superficial tiny blood vessels in the skin that appear as red marks. Just a few treatments with the KTP laser can significantly improve the appearance of erythematous acne scars. There is no downtime after KTP treatments for post-inflammatory erythema, and some improvement can be appreciated within weeks after the first KTP laser treatment. The KTP laser is also used to treat broken capillaries on the face (often seen around the nose) and to remove brown spots from the skin.
