Acne, blackheads and whiteheads
Superficial chemical peels may help selected cases of comedonal acne, including blackheads and whiteheads, and mild inflammatory acne3,7. A systematic review of 12 randomised trials involving 387 participants found potential benefits, although limitations in the studies prevented firm conclusions about which peeling agent was best3.
Established acne medicines remain central to treatment, and the 2024 acne guideline found insufficient evidence to make a formal recommendation for chemical peels4. A peel can therefore be discussed as an additional option for an appropriate concern, while the underlying acne continues to receive medical care7.
Our acne treatment guide explains how severity, scarring risk and previous treatment influence that plan. It is particularly useful when breakouts keep returning despite changes in skincare.
Brown acne marks and uneven pigmentation
Flat brown marks after acne are a form of post inflammatory hyperpigmentation, which differs from an indented scar6. Selected superficial peels can help these pigment changes, with care taken to avoid irritation that could produce further darkening6,7.
Melasma requires a broader approach that includes sun protection and appropriate topical treatment5. Chemical peels may be considered as an adjunct, while maintenance remains important because pigmentation can recur5.
Read our acne marks and acne scars guide for the distinction between colour changes and changes in texture. Our pigmentation assessment guide explains why the diagnosis should come before choosing a procedure.
Rough texture and fine lines
Chemical peels can improve selected surface changes associated with sun exposure, including roughness and fine wrinkles1,2. The extent of improvement depends on the treatment depth and the nature of the concern1.
Facial hollowing and substantial skin laxity require a different assessment from surface roughness1. During consultation, we distinguish these concerns so the proposed treatment matches the change you hope to see.
Can chemical peels improve indented acne scars?
Indented scars involve changes beneath the skin surface, so a superficial facial peel has a different role from a procedure directed at scar structure6. Depending on the scar type, options may include microneedling, fractional resurfacing, subcision or focal chemical treatment6.
TCA CROSS is a targeted technique for selected scars, particularly ice pick scars, rather than the same procedure as a superficial peel applied across the face6. Our scar treatment guide explains why scar shape and depth influence treatment selection.
Which chemical peel is suitable for my skin?
The acid name is only part of the decision. Concentration, formulation, application time and the condition of the skin all influence how a peel behaves2,3.
The comparison below describes ingredients used in professional peeling. Your consultation establishes the proposed preparation and its purpose, rather than asking you to choose an acid yourself.
| Ingredient | Where it may have a role | What matters when selecting it |
|---|
| Glycolic acid | Superficial texture changes, acne and selected pigmentation concerns2,3,5 | Formulation and application determine the response2. |
| Salicylic acid | Blackheads, whiteheads and selected acne concerns3,7 | Its oil solubility and exfoliating activity are relevant to follicular blockage7. |
| Mandelic acid | Selected acne and uneven tone concerns, sometimes within combination preparations2,3 | Tolerability and results depend on the complete preparation2. |
| Lactic acid | Superficial exfoliation and selected uneven pigmentation concerns2,5 | Suitability depends on the skin condition and treatment protocol5. |
| Trichloroacetic acid, or TCA | Selected pigment, resurfacing or focal scar treatments2,6 | Application technique and depth substantially change its role and recovery2,6. |
A stronger concentration does not automatically make a peel more suitable. Depth control and an appropriate endpoint matter more than pursuing maximum exfoliation2,8.
What happens during a chemical peel appointment?
Assessment and preparation
The assessment reviews your skin, current products, medicines, previous procedures and any history of cold sores or unusual healing8. Active infection, open skin or an eczema flare in the treatment area are reasons to address the underlying problem before peeling8.
Please mention pregnancy, breastfeeding or fertility treatment before scheduling. Bring details of upcoming travel, outdoor activities or important events so these can be considered when discussing recovery.
Application and monitoring
The skin is cleansed and prepared before the solution is applied, with vulnerable areas protected where appropriate2,8. Tingling, warmth or stinging can occur, and the skin response is monitored throughout treatment2.
Removal or neutralisation follows the requirements of the particular preparation, as different peels have different endpoints2. Afterwards, the discussion turns to moisturising, sun protection and when to resume your usual products8.
