No7 glycolic peel: what to know

Glycolic acid is an exfoliating ingredient that can smooth rough texture and help unclog surface debris. It may be used in routines addressing acne, comedonal acne, keratosis pilaris, sun spots, or uneven tone, but it does not treat every cause of a mark or rash. People with active irritation, open skin, or a history of pigment changes after inflammation may need a gentler plan. A peel can sting briefly and may leave skin temporarily dry or sensitive.

Patch-test as the product instructions advise, then use only the stated amount and frequency on clean, dry skin. Keep it away from eyes, lips, nostrils, and broken skin. Do not layer it on the same evening with other strong exfoliants, retinoids, or irritating acne products unless a clinician has advised this. Moisturise, avoid picking, and protect treated skin from sunlight with clothing and a suitable sunscreen. Stop if burning, swelling, blistering, or marked redness develops.

Get medical advice for persistent pain, blistering, raw areas, spreading redness, or a sudden darkening of treated skin. A dermatologist can assess whether a persistent patch is [Melasma](/conditions/melasma/), [Post-Inflammatory Hyperpigmentation](/conditions/post-inflammatory-hyperpigmentation/), or another condition rather than repeatedly exfoliating it.

Is glycolic acid suitable for my skin tone and current condition? Which products should I pause? How should I respond if my skin becomes darker, raw, or unusually sensitive?
