Before you undergo laser acne scar treatment, it’s good to know the type of scarring you have. Acne scars can be categorized into two main groups, .i.e.,
- Atrophic scars (indented) – They are caused by lack of enough collagen formation during the acne healing process.
- Hypertrophic scars (raised) – They’re caused by excess tissue/collagen formation during healing.
These two categories can be further divided into four subcategories which include:
Ice pick scars are the most difficult to treat. This is because they are narrow V-shaped holes that go deeper into the skin than other types of scarring, due to insufficient production of collagen during healing.
These types of atrophic scars are wide with oval or circular depressions that make the skin look pitted. The sides if boxcar scars are sharply angled, and the depressions can be either shallow or deep. The shallower the boxcar scars, the more they’ll respond to laser treatments.
These scars are characterized by their round edges and wavy, rolling depressions that make the skin look rugged and uneven. They are formed when collagen fibers develop between the subcutaneous tissue and the skin. These fibrous bands pull the skin inwards, creating the rolling appearance of these scars.
These are raised scars that are most common on the torso but can also appear on any other part of the body. Overproduction of collagen by the skin causes these scars to grow above the normal skin surface. Keloid scars, on some occasions, can continue to grow long after the affected part of the skin has healed.
