- Acne scars are generally of 2 types – depressed scars and raised scars.
- Depressed scars, also known as ice pick scars, can be shallow or deep.
- Shallow ones can give the skin a typical wave-like appearance making it look old and loose. The deeper ones can be more deforming making the skin appear pitted.
- Raised scars, also known as keloids, can appear quite unsightly
