Hi, Abbie. Acne scars are caused by damage to the deeper part of the skin (Dermis). There are 3 different types of acne scars: 1. "Ice-pick" scars that have a small opening but go deeper into the skin. 2. "Boxcar" scars are usually wider and more shallow, with steep, almost vertical walls. 3. Soft rolling scars that can be circular or linear. These are often greater than 4 mm in diameter and have gently sloped edges that merge with normal-appearing skin.
Acne scars can be improved by minimally invasive treatment that are available today in many Dermatologists offices. Systems that use non-insulated microneedle RF technologies (such as EndyMed’s Intensif system) seem to be more efficient and safe than the fractional lasers, especially on darker skin types.
