Glycolic acid is increasingly recommended for exactly this — and for good reason.

What is Glycolic acid

Glycolic acid is the smallest-molecule AHA, exfoliating deeply and renewing the skin surface.

How Glycolic acid helps for post-acne marks

Post-acne refers to lingering marks and unevenness left after breakouts. In this scenario Glycolic acid works with purpose — glycolic acid is the smallest-molecule AHA, exfoliating deeply and renewing the skin surface. As a result, used consistently, it gently improves the skin for post-acne marks.

How to use it

  • Cleanse with a gentle, non-stripping product.
  • Apply glycolic acid to dry skin, starting 2–3 times a week.
  • Seal with a moisturiser to support the barrier.
  • Always use SPF 30+ in the morning.

Precautions

Start with low strengths 2–3 times a week and avoid pairing with retinol on the same night. Don't pick at breakouts — that's the main cause of marks and scars.
