Not All Acne Scars Are the Same – Here’s What You Need to Know

Not All Acne Scars Are the Same – Here’s What You Need to Know

Acne is frustrating enough on its own, but the scars it can leave behind often linger long after the breakouts have cleared. While many people refer to “acne scarring” as one problem, the truth is, there are several different types, and each responds best to specific treatments. At Glass Face, we take a tailored, clinical approach to acne scarring because no two skin journeys are the same. Knowing what type of scarring you're dealing with is the first step towards treating it effectively and safely.

So, What Are the Types of Acne Scarring?

Acne scars fall into two main categories: atrophic (indented) and hypertrophic (raised). Most people experience a combination of these, and each type behaves and responds differently.

1. Ice Pick Scars
These are narrow, deep scars that look like small punctures in the skin. They can be tricky to treat because they often reach into the deeper layers of the skin.
Best treated with:

  • Microneedling (e.g. Dermapen 4™)
  • TCA CROSS
  • Laser resurfacing

2. Boxcar Scars
These are wider and have sharper edges, creating a pitted or crater-like appearance. They usually form after severe acne or inflammation.
Best treated with:

  • Microneedling with radiofrequency
  • Medium-depth chemical peels
  • Laser treatments or subcision

3. Rolling Scars
These cause the skin to appear uneven and wavy. They're typically caused by long-term, inflamed acne and are often linked to a loss of collagen in the deeper dermis.
Best treated with:

  • Microneedling
  • Collagen induction therapies
  • Injectable filler treatments (in some cases)

4. Post-Inflammatory Pigmentation/Erythma (PIH/PIE)
While technically not a scar, PIH/PIE refers to the flat, brown or red marks left behind after spots heal. These fade over time but can linger for months, particularly in darker skin tones.
Best treated with:

  • Medical-grade peels (e.g. Mesoestetic Melanostop or Cosmelan)
  • Targeted skincare with AHAs, retinoids or pigment inhibitors
  • Sun protection (always)

5. Hypertrophic and Keloid Scars
These are raised, thicker scars caused by excess collagen production during healing. They’re more common on the back, chest or jawline.
Best treated with:

  • Steroid injections
  • LED therapy
  • Specialist referral for keloid management

Why Diagnosis Matters

Trying to treat acne scars without understanding which type you have is a bit like taking a guess at a prescription. The wrong approach can waste time, money and sometimes even make things worse. At Glass Face, we use clinical skin assessments to properly diagnose scarring and create a personalised plan, often combining multiple treatments for the best outcome. We also focus on treating active acne first, to prevent further scarring from developing.
