How acne scars are formed

Many adolescent boys and girls are deeply troubled by the problem of acne on their faces. Acne not only causes redness, swelling and pain in the facial skin area, but also easily leaves acne marks on the face after the acne heals. At the same time, acne patients must go to the hospital for treatment in time. When acne develops to a serious level, the treatment methods used are more complicated. The following article explains the formation mechanism of acne scars.

Acne scars are a repair response of the body to tissue damage. When skin damage reaches deep into the dermis or a large area of ​​epidermis is damaged, the epidermis in that area cannot regenerate and will be replaced by dermal fibroblasts, collagen and proliferating blood vessels, resulting in acne scars. Acne scars are caused by infection, inflammation or external force. This is often because acne is not treated promptly and appropriately when it occurs. The inflammatory response of skin cells causes damage to the skin tissue, resulting in scars.

Due to the various types of acne, there are also many forms of acne scars. The more severe the inflammatory reaction during an acne attack, the more severe the skin tissue is damaged. The deeper the inflamed area, the deeper the skin tissue is damaged, and the more severe the acne scars that may be left in the future will be.

When acne breaks out, it causes blood vessels to dilate. After the acne disappears, the blood vessels do not shrink immediately, resulting in some flat red spots. The inflammatory response of skin cells causes damage to the skin tissue. The pigmentation after inflammation will leave a dark and dirty color in the places where the red acne has grown, thus forming acne marks. When acne persists and the acne marks continue to increase, various cells release a variety of cytokines, which lead to abnormal arrangement of skin collagen and matrix. Coupled with the influence of microcirculation and free radical factors, lymphatic return is reduced, and local edema occurs, which forms acne scars.
