What should you know about mandelic acid treatment?

At home, treatment may be a cleanser, leave-on liquid, serum, or pad. In a clinic, it may mean a practitioner-applied peel with a planned contact time and aftercare. Both use mandelic acid, but they differ in concentration, supervision, preparation, and depth of exfoliation. A treatment can improve the appearance of roughness or uneven tone without addressing every cause of those changes.

Temporary warmth, tingling, dryness, or light flaking can occur. Irritated skin is more vulnerable to discomfort and pigment changes, particularly after sun exposure, so treatment timing and barrier health matter.

Before a professional treatment, disclose prescription creams, recent waxing or shaving, cold-sore history, active rashes, and any tendency to develop dark marks. Follow the clinic's instructions about pausing exfoliants and retinoids. Afterwards, use gentle cleansing, moisturiser, and sunscreen; avoid picking flakes, hot water, vigorous exercise if advised, and unapproved active products until the skin settles. Never use a home product to imitate a clinic peel.

Contact the treating clinician for increasing pain, swelling, crusting, blistering, or redness that spreads rather than settles. Seek urgent help if facial swelling affects breathing or swallowing. New persistent dark or pale patches also deserve review, because ongoing inflammation may require a different plan.

Ask what concern the treatment is intended to address, whether the skin barrier is ready, what aftercare is required, and which medicines or procedures should be separated from it.
