A type of acne scar, a crater is an indentation of the skin caused by severe acne. As acne worsens, inflammation and festering can spread to the dermal layer of the skin. The result,Damage destroys the tissue around the pore that was forming the pimple, causing it to become indented and cratered.The T-zone is the area that produces most of the sebum. In particular, the T-zone, such as the nose and between the eyebrows, where sebum production is high, and the cheeks and mouth, where acne tends to form due to dryness, are the most likely places for crater-like acne scars to appear. If inflammation continues for a long period of time or if a pimple is crushed, it is easy to develop crater-like pimple scars, so it is important to treat the symptoms as soon as possible.
