It might seem that, once you’ve cleared up your acne, you should be free of any skin issues. However, for many who once dealt with acne, they are left with frustrating residual acne scars.
Read on to learn more about the different types of marks, as well as the best serums for acne scars.
The Types of Acne Scars and Their Causes
Acne scars are caused by moderate to severe acne. Typically, they come from inflamed blemishes trying to heal themselves. There are two main types of acne scars that acne-sufferers can experience: atrophic and hypertrophic.
- Hypertrophic scars are also referred to as “keloid scarring.” These scars occur when the body produces an excess of collagen during the healing process of a wound. This results in raised tissue on the surface of the skin. Additionally, they can appear as red acne marks or even look like acne.
- Atrophic scars (or “depressed scarring”) have the opposite effect. They occur when there is a loss of tissue, resulting in an indent in the skin. The most common forms of atrophic scarring are ice pick, boxcar, and rolling. Ice pick scars are small but noticeable holes in the skin. Boxcar scars have defined borders with a flat bottom surface, and resemble chicken pox scars. Rolling scars don’t have clearly defined borders, and are commonly found on the cheeks.
In most cases, atrophic and hypertrophic scars don’t fade on their own. They typically require some form of treatment to reduce their appearance.
Dark Acne Scars aka 'Hyperpigmentation'
Post-inflammatory hyperpigmentation is another issue that many people with acne have to deal with. This visually appears as a dark spot on the skin where a pimple once existed. While often referred to as a scar, it is actually just an acne mark, since it doesn’t have to do with a loss or excess of tissue. Typically, hyperpigmentation with clear up on its own within 4 to 24 months. However, it can be treated to speed up the process.
