Acne scars can be frustrating because they often remain long after breakouts have cleared. Not all scars are the same, and understanding the type you have is the first step toward effective treatment. There are mainly three categories of acne scars: atrophic, hypertrophic, and keloid scars. Each requires a different approach for improvement.

Atrophic scars are the most common and appear as indentations in the skin. They are further divided into three subtypes: icepick, boxcar, and rolling scars. Icepick types are characterized by their narrow, vertical depth. Boxcar scars are wider with sharp edges, similar to chickenpox scars. Rolling scars create a wavy texture on the skin due to bands of tissue pulling the epidermis down. Treatments for atrophic scars often focus on stimulating collagen production. Options include microneedling, chemical peels, laser resurfacing, and dermal fillers. Microperforations from fine needles activate the skin’s natural repair response. Fractional laser systems promote remodeling by targeting microscopic zones. Hyaluronic acid injections restore volume to depressed areas.

These scars are elevated yet confined to the initial wound site. They are usually pinkish with a rubbery consistency. Unlike keloid scars, they do not spread beyond the original area. Hypertrophic scars often respond well to clinical-grade silicone formulations. These help flatten and soften the scar tissue over time. Corticosteroid injections can also reduce inflammation and shrink the scar. Compression garments enhance the effect of laser therapy.

Keloid scars are more aggressive and grow beyond the original site of the acne breakout. They are often hyperpigmented and cause discomfort or tenderness. Keloids are more common in people with ethnic backgrounds with higher pigmentation. Treatment is more challenging because keloids have a frequent rebound after excision. Options include intralesional steroids to reduce volume. Cryotherapy to freeze the tissue. non-ablative lasers to smooth surface irregularities. And in some cases, excision combined with post-op radiotherapy. It’s important to consult a skin specialist before attempting any procedure for keloids due to their high risk of reformation.

Prevention is key. Avoid touching, popping, or prodding breakouts. This triggers deeper tissue damage. Consistent acne management prevents collagen breakdown. UV rays worsen scar discoloration and impede regeneration.

If you’re unsure what type of scar you have, see a skin doctor. They can diagnose scar subtype, propose optimal interventions, and build a customized roadmap. Patience is important because scar improvement often takes weeks to months. With the right approach, many acne scars can be substantially smoothed, improving both skin texture and confidence.
