How effective are the various types of chemical peels for acne scars?

Doctor's Answer

Medical-grade Chemical Peels are highly effective treatments for Acne Scars.

It is proven that TCA Cross 70% alone can give you good to excellent improvement (> 50% improvement) of atrophic acne scars, especially severe boxcar scars.

I routinely perform TCA Cross for ice pick scars and deep box acne scars.

TCA Cross, which stands for Trichloroacetic acid, is a medium to deep chemical peel. There is a wide range of concentrations of TCA cross (from 35% to 100%). I usually combine this with subcision, Lasers and Rejuran injections for enhanced results in treating ice-pick scars.

Superficial chemical peels are used for treating active acne - comedones (blackheads/whiteheads) and pustules.

Examples of superficial chemical peels include: glycolic acid and salicylic acid. Unfortunately, they do not improve acne scars significantly.


Doctor-performed chemical peels are of higher potency (due to higher concentration of acid) and are more effective as compared to spa or home chemical peels.

Do note that TCA cross peels must be performed by a certified doctor!


All the best!

Warmest regards,

Dr. Justin Boey
