What to know about Allies of Skin mandelic products

Mandelic acid is an alpha hydroxy acid used to loosen surface skin cells. It may help smooth rough texture, reduce the appearance of dullness and support a more even-looking tone, but results and tolerance vary.

The word identifies the exfoliating ingredient, not a professional peel or a promise of a particular result. The complete ingredient list and directions matter because other active ingredients in the same formula can change how irritating it feels.

A leave-on home product generally acts more gently than a clinic-applied chemical peel. Sensitive, dry, eczema-prone or recently treated skin may sting or become inflamed more easily.

Follow the instructions on your exact product. Patch-test on a small area first, then begin on clean, dry, unbroken skin less often than the maximum label schedule. Increase only if there is no persistent burning, redness or scaling.

Keep it away from the eyes and lips. A plain moisturiser can reduce dryness. Avoid layering it in the same routine with other exfoliating acids, scrubs or retinoids until you know how your skin responds, and use broad-spectrum sunscreen during the day.

Stop using the product and rinse gently if you develop intense burning, marked swelling, blistering or weeping skin. Seek urgent medical help for facial swelling, widespread hives, breathing difficulty or eye exposure that continues to hurt after rinsing.

Arrange a dermatology review if irritation does not settle after stopping, dark marks appear after inflammation, or the concern you are treating is changing, bleeding or failing to heal.

Ask whether mandelic acid suits your skin barrier and main concern, which of your current exfoliants or retinoids should be separated from it, and how to restart after irritation. Mention eczema, rosacea, pregnancy, breastfeeding and any recent laser, waxing or peel treatment so the advice fits your circumstances.
