The product does not specify a fixed frequency, so the sensible approach is to start slowly and adjust based on how your skin responds. A common starting point for a wash-off glycolic acid mask is once a week. If your skin tolerates it well, you may increase to twice a week, but more frequent use does not mean faster results — consistent weekly use is usually enough to maintain the smoothing effect.
Apply the mask to clean, dry skin in an even layer, avoiding the eye area. Follow the contact time given on the packaging; if it is your first time, you may rinse it off a little earlier. Rinse thoroughly with lukewarm water, pat the skin dry, and follow with a gentle moisturizer. Do not leave the mask on overnight — it is a wash-off product.
Introduce it thoughtfully into your routine, especially if your skin is reactive or you already use retinoids, acids or strong exfoliants. Avoid combining too many active products at once: on the day you use the mask, skip other exfoliating treatments and, if you use a retinol or acid serum daily, consider skipping it that evening. Layering several strong actives can cause irritation even when each one is well tolerated on its own.
After exfoliation, the skin can be more sensitive to UV, so pay extra attention to sun protection in the following days, especially if you are outdoors a lot. If you are pregnant, breastfeeding, managing a chronic skin condition, or taking medication, consult a specialist before adding a glycolic acid product to your routine.
