Chemical peels can be a useful addition to an acne treatment plan, particularly for people with mild to moderate acne, lingering acne marks, or uneven skin texture. They are typically performed by a dermatologist or other qualified skincare professional and are used alongside—not as a replacement for—other acne treatments.
How chemical peels work
A chemical peel involves applying a solution to the skin that exfoliates the outer layers. This process can:
- Remove dead skin cells that contribute to clogged pores.
- Promote the growth of new, healthier skin cells.
- Improve skin texture and tone.
- Reduce the appearance of post-acne marks over time.
Benefits for acne
Depending on the type and strength of the peel, treatment may:
- Help keep pores clear: By exfoliating the skin, peels can reduce the buildup of dead skin cells that contribute to blackheads and whiteheads.
- Reduce inflammation: Some peeling agents have anti-inflammatory properties that may help calm acne lesions.
- Improve post-inflammatory hyperpigmentation: Dark spots left behind after acne heals may fade more quickly with repeated treatments.
- Enhance the effects of topical treatments: By removing surface buildup, chemical peels may improve the penetration of certain topical acne medications. Your clinician may advise temporarily stopping some acne products before or after a peel to reduce irritation.
Common peeling agents
Healthcare professionals may use ingredients such as:
- Salicylic acid: Oil-soluble and particularly useful for acne-prone skin because it penetrates into pores.
- Glycolic acid: An alpha hydroxy acid (AHA) that exfoliates the skin’s surface and can improve texture and discoloration.
- Lactic acid: A gentler AHA that exfoliates while helping maintain skin hydration.
- Trichloroacetic acid (TCA): Used in medium-depth peels for selected patients and specific skin concerns.
The most appropriate peel depends on your skin type, acne severity, and treatment goals.
What to expect
Most people need a series of treatments, often spaced several weeks apart, to achieve the best results. After a peel, it’s common to experience:
- Mild redness
- Dryness or flaking
- Temporary sensitivity
Recovery time varies depending on the depth of the peel.
Important considerations
Chemical peels should be performed or recommended by a qualified healthcare professional, especially for people with active acne, darker skin tones, or a history of scarring, because treatment choice and technique affect both safety and results.
After a peel:
- Use a broad-spectrum sunscreen daily, as the skin is more sensitive to sunlight.
- Follow the aftercare instructions provided by your clinician.
- Avoid picking or peeling flaking skin, as this can increase the risk of irritation or scarring.
When incorporated into a comprehensive acne management plan that may include topical medications, oral treatments, and a consistent skincare routine, chemical peels can help improve both active acne and some of its after-effects.
