What should you know about Paula's Choice mandelic acid?

Mandelic acid is an alpha-hydroxy acid that loosens connections between surface skin cells. This can make rough texture look more even and help other products spread more smoothly. Its exfoliating action may also support care for blemish-prone skin, although persistent or inflamed acne needs a proper assessment. Sensitivity varies with concentration, frequency, other actives, and the condition of the skin barrier.

Patch test on a small area, then apply a thin layer to clean, dry skin at the frequency on the label. Begin less often if your skin is reactive. Follow with moisturiser and use sunscreen each morning. Avoid applying it to cuts, active dermatitis, or recently waxed skin. Do not combine it in the same routine with several exfoliants, retinoids, or irritating acne products until a professional has advised you. A clinician may use a stronger formulation or a chemical peel when home care is not enough.

Stop using the product and obtain medical advice if you develop intense burning, swelling, blistering, or a persistent rash. Seek assessment for painful nodules, scarring, sudden pigment change, or a diagnosis that remains unclear. A dermatologist can separate irritation from an untreated skin condition and tailor the plan.

Is mandelic acid suitable for my skin barrier and current products? How often should I apply it? Would a chemical peel be appropriate for my concern? Which signs mean I should stop?
