If you’ve ever had acne, you may have been left with acne scarring. If you have acne now, you may be worried you’ll get scars.
Here we’ll let you know the different types of acne scarring, and we’ll give you advice about how you can treat them.
Acne is a skin condition that causes spots, inflammation, and sometimes scarring. People usually get it on their face, but it can appear on the neck, back, chest, and shoulders too. There are also a lot of different types of acne.
Acne doesn’t always cause scarring, but it can when the more serious types of acne spots form, called nodules and cysts.
These larger spots can cause inflammation in the surface layers of your skin, and this swelling can press into lower layers and damage the structures there. This damage to the deeper levels of your skin is what causes the scars.
Scars can also form if you squeeze your spots to burst them, as it can damage the skin beneath the spots and make the spots themselves worse. We know how tempting it can be to give them a squeeze, particularly when you can see white heads on your spots, but try hard not to, as in addition to giving you scars, it can cause infections in your spots to spread further into your skin too. So it’s best to leave them alone.
Scars are scars, right? Well, no. Different types of acne scars can respond differently to treatments, so knowing what kind of scar (or scars) you have, can help you pick the best treatments for your skin.
There are two main types of acne scarring, depressed and raised.
Depressed scars, also called atrophic scars, form when there’s not enough collagen in damaged skin tissue when it heals after a spot clears up. Collagen acts as a structural support in skin, think of it like the frame which holds up a house. If your skin loses collagen then it can sag in places, forming depressions on your face. These depressions are visible on the surface of your face as the top layers of skin dip down into them. There are three types of depressed acne scar:
These are generally shallow, circular scars, but often with defined, almost sharp edges, giving them the appearance of small boxes (kind of). They often form where a large nodule or cyst has healed. Although they’re usually shallow, they can sometimes be deep, with deeper scars being harder to treat.
These scars are narrower than boxcar scars, and usually look like small holes, like an ice pick has been pressed into the skin. They can be harder to treat than boxcar scars, as they often extend deeper into the skin.
These are roughly circular, like boxcar scars, but are usually wider. They typically have an irregular appearance with less of a defined shape than boxcar scars, often with more curved edges.
Raised acne scars, also called hypertrophic scars, are the opposite of depression scars in that they are raised from the skin, rather than indented. And whereas depression scars are caused by not enough collagen in damaged skin, raised scars are caused by the presence of too much collagen. They look like raised bumps and lines on the skin, and although they do form on the face, they’re more common on the back and chest.
Unfortunately, there’s no guaranteed way to prevent acne scars. If you have acne, scarring will always be a risk. But you can do the following to help minimise your chances of getting scars and to limit their severity:
OK, we have to say this. Treating acne scars can be difficult. Most scars are permanent. No matter the treatment, they’ll never completely disappear. Treating acne scars is more about minimising their appearance, rather than getting rid of them forever. With that said, many treatments are effective though, and they can visibly reduce the prominence of your scars. You’ve got the following options:
You can buy a range of over-the-counter or prescription products which you can use at-home to treat your acne scars, including:
You can also try a range of treatments offered by dermatologists and other healthcare professionals to reduce the appearance of acne scars, including:
Acne scars can be removed surgically, although this is usually an option reserved for more serious and deeper scarring, as well as raised scars. A dermatologist or surgeon can remove a scar, but this will leave a small scar in its place, so surgery is often best suited for larger, more prominent scars.
Knowing what kind of acne scar you have is the first step in treating them. But you need to have realistic expectations as most scars are permanent. However, there are a range of treatments that can make them less visible.
