Pitted scars are a common problem that occurs when skin tissue damage leads to the degradation of collagen, elastin fibers, and fatty tissue beneath the skin. These scars are often caused by improper squeezing of acne, pimples, or pustules, as well as scratching or breaking chickenpox blisters prematurely. They can also result from wounds after surgery, accidents, or burns when not treated properly. While these scars cannot fill on their own, specialized treatment methods may help reduce their appearance.
According to Dr. Vo Thi Tuong Duy, a specialist in Dermatology and Skin Aesthetics at Tam Anh General Hospital in Ho Chi Minh City, pitted scars make up a significant portion of cases compared to hypertrophic and keloid scars. These scars develop over time as the body is unable to completely regenerate tissue, leading to dents in the skin of various shapes and sizes.
There are several effective treatment methods for pitted scars, including laser therapy, biological skin replacement, platelet-rich plasma, needle rolling, and scar removal. Laser treatments such as fractional CO2 laser can help stimulate cell growth and skin regeneration to reduce the appearance of pitted scars. Biological skin peeling involves applying acid-based solutions to accelerate collagen production and skin regeneration in concave areas. Platelet-rich plasma therapy utilizes growth factors to stimulate cell proliferation, collagen production and blood vessel proliferation in the skin. Needle rolling creates fake lesions on the skin to break down scar tissue and increase collagen and elastin production
