Understanding Acne Scars & Pigmentation

Not all acne scars are the same—and neither are the treatments. Knowing what type of scar or pigmentation you're dealing with can help you choose the right skincare to fade marks more effectively. Here's a quick guide to the most common types and how to treat them.

🟣 Post-Inflammatory Hyperpigmentation (PIH)

These are flat, dark spots left after acne heals. They’re more common in medium to dark skin tones and are not true scars.

Best Ingredients to Use:

  • Niacinamide – brightens and evens out skin tone
  • Vitamin C – fades dark spots and boosts radiance
  • Tranexamic Acid – targets stubborn pigmentation
  • Sunscreen – prevents spots from getting darker

🔴 Post-Inflammatory Erythema (PIE)

These are red or pink marks caused by inflammation, usually seen in fair skin types. Unlike PIH, these are from blood vessel damage—not melanin.

Best Ingredients to Use:

  • Centella Asiatica – calms redness and supports healing
  • Azelaic Acid – reduces inflammation and redness
  • Green Tea Extract – antioxidant-rich and soothing
  • Niacinamide – also helps with redness

⚪ Atrophic (Indented) Scars

These appear as shallow or deep depressions in the skin—like ice pick or boxcar scars—after deeper acne damage.

Best Treatments Include:

  • Retinoids (like Retinol or Bakuchiol) – encourage collagen production
  • Exfoliating Acids (AHA, BHA, PHA) – smooth texture and fade discoloration
  • Peptides & Growth Factors – help rebuild skin structure

💡 Final Tips:

  • Always use sunscreen daily - UV exposure worsens scars and slows healing.
  • Be patient. Most products need several weeks of consistent use.
  • Don’t overdo it. Focus on calming and healing - especially if your skin is sensitive.
