Chemical peels are one of the most effective treatments for acne scars and hyperpigmentation — but choosing the wrong depth can waste your money or harm your skin. Here is how to decode them.
How Peels Work
A chemical peel applies an acid solution that removes damaged surface layers so fresher, more even skin can surface. The depth — how deep the acid works — determines the results and the recovery.
The Three Depths
- Superficial peels (e.g., mild AHAs/BHAs): gentle, little downtime, great for dullness, mild pigmentation and texture. Best done in a series.
- Medium peels (e.g., stronger TCA): reach deeper for more stubborn pigmentation and acne scarring, with some peeling and downtime.
- Deep peels: dramatic results for significant scarring, but require professional supervision and real recovery time.
Choosing the Right One
For most people with acne scars or hyperpigmentation, a series of superficial-to-medium peels done by a professional is the safest, most effective path. Deeper peels should always be medically supervised — and on darker skin tones, gentler approaches reduce the risk of post-inflammatory pigmentation.
Aftercare Is Everything
Whatever the depth, strict sun protection afterwards is non-negotiable — sun exposure on peeling skin can undo results and worsen pigmentation.
