Understanding and Treating Acne Scars
About 15% of people experience post-acne scars after their active acne subsides. If you're wondering what kind of scars you have and how to treat them, you're in the right place.
Types of Acne Scars
Post-acne marks fall into two categories:
- Flat, Smooth Spots: Brown or pink marks that don’t alter skin texture.
- True Acne Scars: These alter skin texture and include:
- Icepick Scars: Small, deep pits.
- Boxcar Scars: Shallow or deep depressions with well-defined edges.
- Rolling Scars: Gentle slopes blending into normal skin.
- Hypertrophic Scars: Raised scars within the original pimple's boundary.
- Keloid Scars: Raised scars larger than the original lesion.
Why Do Acne Scars Form?
Acne scars result from disrupted collagen production during healing. Insufficient collagen can cause atrophic (depressed) scars, while excessive healing leads to hypertrophic or keloid scars. Picking or inflamed lesions often worsen scarring.
Treating Post-Acne Spots
Flat Brown Spots:
- Control Acne: Start with effective anti-acne treatments.
- Sunscreen: Protect your skin from UV rays to prevent darkening.
- Dark Spot Removers: Use products with hydroquinone, arbutin, retinoids, or plant-based complexes.
Flat Pink or Red Spots:
- These marks typically fade in 2–3 months. For faster results, consider IPL (Intense Pulsed Light) or laser treatments performed by a dermatologist.
Treating Real Acne Scars
Topical Options:
- Retinol treatments promote collagen production and smooth skin.
- Peptide scar creams can accelerate healing and improve newer scars.
- For dark spots, consider a Dark Spot Remover, which complements acne treatment.
Supplements:
Vitamins A, B5, C, and minerals like zinc and selenium support wound healing. Avoid high levels of biotin and vitamin E, which may counteract benefits. Opt for supplements designed specifically for acne-prone skin.
In-Office Treatments
Microneedle Radiofrequency:
The gold standard for acne scars, this treatment uses gold-plated needles to stimulate collagen with minimal discomfort and downtime.
Fractional Lasers:
- Ablative lasers resurface the skin by removing layers.
- Non-ablative lasers stimulate collagen without surface damage.
Subcision:
Collagen bands pulling the skin down are released with a needle or scalpel, lifting the skin for a smoother appearance.
Injectable Fillers:
Dermal fillers temporarily elevate depressed scars but require regular maintenance.
Preventing Acne Scars
The best prevention is early and effective acne treatment. Avoid picking at pimples and ensure your skincare routine includes sunscreen and treatments to control breakouts.

Conclusion
Preventing acne scars begins with effectively treating active acne. For flat marks, dark spot correctors can help. For deeper, textured scars, in-office treatments like microneedling or lasers are often necessary. With the right approach, you can achieve smoother, healthier skin.
