Acne scars are unsightly. No one wants them, and you’d like to treat them as soon as possible. But how you treat an acne scar will depend on which kind of scar it is. Here, we discuss the different types of acne scars to help you on your path to recovery:
Ice Pick Scars
Ice pick scars look just like their namesake—they are deep and narrow and look as if an ice pick or a needle pierced your skin. While the scar may seem small, it actually extends all the way into the dermis layer of the skin. These scars develop after an infection from a cyst or another deep blemish.
Boxcar scars are deeper than ice pick scars. They appear like round or oval depressions in the skin, creating a pitted appearance. A boxcar scar will develop after an acne breakout. The acne destroys the collagen in your skin, resulting in tissue loss. Since the skin has no support, it creates a depression in the area.
Sometimes during acne breakouts, fibrous bands of tissue develop between the skin and the subcutaneous tissue below. The bands pull at the epidermis layer of the skin, creating a series of depressions across the skin and forming an uneven appearance. Known as rolling scars, they are similar to boxcar scars but are not explicitly defined.
Finally, there are hypertrophic scars. Unlike the previous three, which create depressions in the skin, hypertrophic scars create a firm, raised surface. They’re most commonly found on the torso, but they can appear anywhere. They’re often common after a deep wound or skin trauma.
A severe type of hypertrophic scar is known as a keloid. These grow larger than the original wound and can continue to grow even after the original wound has healed.
