Understanding Acne Scars: Causes and Treatments

Acne scars can be a lasting reminder of past breakouts, affecting both appearance and confidence. Understanding the science behind acne scars and the treatments available can help you find the best solution for smoother, healthier skin.

The Science Behind Acne Scars

Acne scars form when severe inflammation from acne lesions damages the skin and underlying tissues. This triggers the skin’s natural healing process, which involves collagen production. However, if too little or too much collagen is produced, scars may develop:

  • Atrophic Scars: Depressed scars, like ice pick or boxcar scars, result from insufficient collagen during healing.
  • Hypertrophic Scars: Raised scars form when excess collagen is produced.

The type and severity of scars depend on factors like the depth of the acne lesion and individual healing responses.

Treatments for Acne Scars

Effective treatments target the damaged skin layers, stimulating repair and collagen production. Here’s a breakdown of popular treatments and how they work:

1. Microneedling

Microneedling involves using fine needles to create tiny, controlled micro-injuries in the skin. These micro-injuries stimulate the body’s wound-healing process, promoting collagen and elastin production. Over time, this reduces the appearance of atrophic scars and improves skin texture.

  • Best for: Mild to moderate atrophic scars.
  • Science: The micro-injuries activate fibroblasts and release growth factors, enhancing skin regeneration.

2. Chemical Peels

Chemical peels use acids (like glycolic or salicylic acid) to exfoliate the top layers of skin, encouraging new cell turnover and reducing scar depth. Medium to deep peels can penetrate further to target deeper scars.

  • Best for: Superficial scars and uneven skin tone.
  • Science: The controlled exfoliation promotes collagen production and removes damaged skin layers.

3. PRP (Platelet-Rich Plasma)

PRP therapy involves injecting plasma rich in platelets, derived from your blood, into scarred areas. The growth factors in PRP boost skin healing and collagen synthesis, making scars less visible over time.

  • Best for: Enhancing other treatments like microneedling for deeper scars.
  • Science: Platelets release growth factors like TGF-β and VEGF, which repair damaged tissues and stimulate new collagen.

4. Polynucleotides

Polynucleotides are DNA fragments derived from natural sources, like salmon, known for their regenerative properties. Injected into the skin, they stimulate cell repair, hydration, and collagen production, improving the appearance of scars.

  • Best for: Atrophic scars needing hydration and repair.
  • Science: Polynucleotides enhance fibroblast activity and promote angiogenesis, improving skin elasticity and texture.

Combining Treatments for Best Results

For severe or mixed scars, dermatologists often recommend combining treatments. For example, microneedling with PRP can enhance collagen stimulation, while chemical peels can improve skin tone before deeper treatments.
