We’re here to share what we know — but don’t take it as medical advice. Talk to your medical provider if you have questions.

Scars can be an unfortunate lasting effect of acne, even after your breakouts clear up completely. And while not everyone experiences post-acne spots that appear after their skin heals from stubborn blemishes—be it acne scars or post-inflammatory hyperpigmentation (which are often confused!)—many people unfortunately do.

True scars will not resolve with a topical skincare product alone, but daily use of your Curology Custom Formula can help speed up the fading of post-acne pigmentation. Acne scars may be more difficult to treat, but there are options out there.

What are acne scars?

The simple answer: acne scars are marks left behind from an acne lesion. The scar forms as a result of the wound healing process (an extremely complex process!).¹ Acne marks can be raised, shallow, or deep, depending on the pimple and how it heals.

What are the types of acne scars?

Your acne scar may appear different depending on the type. There are two major categories of acne scars: atrophic and hypertrophic.²

Types of Acne Scars Infographic

Atrophic acne scars

Also called depressed scars, atrophic scars come in several different forms³:

  • Ice pick. These scars resemble the shape of their name; ice pick scars are wide on the surface and narrow to a point as they go deeper into the skin.

  • Rolling. Characterized by sloped edges, these scars mostly appear on your cheeks and jawline.

  • Boxcar. These scars are indents with sharp edges and are common on the cheeks and jaw.

Hypertrophic acne scars

These acne scars are raised as a result of collagen and fibrosis tissue growing more than necessary. They remain within the borders of the original lesion. Keloids are similar to hypertrophic scars, but they extend beyond the border of the original lesion. They can be itchy and painful to the touch.⁴

What is the difference between acne scars and post-inflammatory hyperpigmentation?

Post-inflammatory hyperpigmentation is a common skin condition that is often incorrectly referred to as “acne scars”. The difference is that post-inflammatory hyperpigmentation appears as dark spots on your skin rather than indents or raised scars. 

Hyperpigmentation is caused by many different things, including sun damage, past skin injuries (such as acne),⁵ genetics, and hormonal changes.⁶

There are a variety of treatments available for post-inflammatory hyperpigmentation, including over-the-counter ingredients such as vitamin C, prescription medications such as tretinoin, and chemical peels.⁷

What are the medical scar treatments available?

If you’re wondering how to get rid of or improve the appearance of acne scars, we need to be honest with you. Depressed, hypertrophic, and keloid scars will not go away with topical treatments (although certain topical medications may help in the long term due to their collagen-boosting effect!). Keep in mind, though, that dermatologists and other healthcare professionals can perform many different in-office procedures that can help improve scarring.⁸

  • Injections. If you have a raised acne scar, an injection of corticosteroids directly into the scar may help flatten the tissue. You might need to have multiple injections for one scar to see a significant difference. If the scar isn’t improving after several injections, you may be better off seeking another type of treatment. 

  • Microneedling (aka collagen induction therapy). This method of treating acne scars stimulates your skin to produce more collagen to heal the scars. The treatment consists of a roller with many small needles going over the affected area to stimulate collagen production over a larger area rather than just a targeted scar.⁹

  • Skin tightening. Dermatologists may use radiofrequency on the skin to reduce the appearance of depressed acne scars. With this treatment, you’ll need multiple appointments and may notice some side effects, including burning and sensitivity to the sun. After a skin tightening appointment, make sure to apply SPF 30 or higher of a broad-spectrum sunscreen to help block harmful UV rays.¹⁰

  • Filler. If you have a depressed acne scar, a dermatologist may use filler to make the indentation less noticeable.¹¹ The filler may be made of collagen or fat from your own body. Keep in mind, though, that filler is typically a temporary treatment.

  • Resurfacing procedures. A common way to fade the appearance of acne scars is through chemical peels, microdermabrasion, and laser skin resurfacing treatments.¹² The procedures work just as the name suggests; they remove layers of skin with the goal that your skin grows back with less prominent scarring. This treatment typically only works for shallow scars, and you may need to try another method to tackle those deeper persistent marks.

  • Surgery. While this might sound drastic, if you have a very noticeable scar you want to fade, and nothing else is helping, a dermatologist may surgically break up the scar tissue to make it less noticeable as it heals.¹³ The surgery is minor, so no need to fear, but this may be the last resort for fading acne scars.

How to help prevent acne scars

The best way to help prevent acne scars is to prevent acne itself. Here are our dermatologist-approved tips on how to help avoid scarring from your blemishes:

  • Hands off! Yes, we know it can be super tempting to pick at those stubborn pimples. But the truth is it’s best to just leave them alone. Picking and popping blemishes can cause damage to the skin that leads to scarring. 

  • Use acne-fighting ingredients. Salicylic acid and benzoyl peroxide are two ingredients that target acne. If you’re prone to breakouts, benzoyl peroxide fights the bacteria that contribute to acne, and salicylic acid unclogs pores (and helps keep them that way!)

  • See a dermatologist for especially large blemishes. If you have an inflamed pimple that just won’t go away, a dermatologist may be able to offer treatment that could help prevent scarring, like the ones discussed above.

  • Stick to your skincare routine. When it comes to acne treatment, consistency and patience are key. A simple skincare routine can help prevent breakouts. It might seem like it’s taking too long for your routine to work, but keep calm and be consistent. Clear skin doesn’t happen overnight!

Helping to prevent acne scars can be tricky, but Curology makes it easier with customized skincare.
