Atrophic scars are a type of skin scar that occurs when the skin loses collagen and tissue during the healing process. These scars appear as depressions or indentations on the skin's surface, often resulting from conditions like acne, chickenpox, or surgery. They can vary in size and depth, affecting the skin's texture and appearance. These scars are different from hypertrophic scars, which are raised above the skin's surface. Atrophic scars can be challenging to treat, but options like laser therapy, microneedling, and dermal fillers are available to improve their appearance. Proper skincare and sun protection can also help minimize their visibility.
