Information on chemical peels
A chemical peel removes the upper layers of the skin in a controlled way with solutions containing acids or enzymes. During renewal, a smoother skin surface and lighter pigmentation are aimed for. The depth and type of peel are chosen according to skin type and goal.
Treatment details
Duration: About 20–40 minutes.
Who it is for: Adults with a suitable skin type who want assessment of pigmentation, acne, superficial acne scars, dullness or fine lines.
Number of sessions: Superficial peels usually 4–6 sessions, 2–4 weeks apart; a medium-depth peel is mostly a single session. The final plan is set by the physician after the examination.
Types of peel
A TCA (trichloroacetic acid) peel works at a superficial or medium depth depending on its concentration. An enzyme peel uses fruit enzymes for gentler renewal in sensitive skin. A pumpkin peel is a superficial peel containing enzymes and acids. Acne peels mostly use pore-active acids such as salicylic acid. A carbon peel, in which a carbon layer applied to the skin is removed with a laser, is a laser-based resurfacing treatment rather than a peel.
Evidence and expectations
Superficial and medium-depth peels have long been used for pigmentation, acne and photoaging. Results depend on the number of sessions, skin type and sun protection; pigmentation may recur.
Possible risks
Redness, stinging, dryness and peeling are expected effects. Less commonly, darkening or lightening, cold sore activation, infection and scarring may occur. The risk of pigment change is higher in darker skin.
Who may not be suitable?
Pregnancy and breastfeeding, active infection or cold sores, recent isotretinoin use, recent intense sun exposure and a tendency to scarring are assessed separately.
Frequently asked questions
How much peeling happens afterwards?
It depends on the type and depth of the peel; mild with superficial peels and more marked with medium-depth peels.
Is sunscreen necessary?
Yes. Regular sun protection after a peel is part of the treatment.
Which peel suits me?
It is decided at the examination according to skin type, concern and expected recovery time.
