What is a post-acne scar?
Acne scars are skin imperfections that can spoil a beautiful face and leave marks on the body. They are the result of severe acne.
There are different types of scars. The following are most frequently associated with acne:
- Atrophic scars: They look like an indentation in the skin’s surface and are sometimes called “ice pick scars”. They appear when a wound does not heal properly and not enough connective tissue is made. The scar develops under the surrounding tissue and a small indent is visible.
- Hypertrophic scars: Hypertrophic scars can be recognised by the fact that they are raised on the skin or the scar tissue. When a spot becomes inflamed, the skin produces “lower quality” tissue. This tissue does not have the same structure as healthy tissue, which explains why it is thicker and more raised than the surrounding skin.
- Keloids: When a hypertrophic scar continues to grow and extend to other areas of the skin, we talk about keloid scars. Keloid scars are raised and a purplish red colour when they first appear, but the colour subsequently fades. This type of scar is only occasionally caused by acne; it is more often associated with burns.
