Predire Paris has several face mask options like gels, creams and sheet masks. Gel and cream masks should be applied to clean, dry skin avoiding eye area. Leave on 5-10 minutes then rinse off. Sheet masks can be applied to clean skin and left on 15-20 minutes before removing the sheet. Use Predire Paris masks 1-2 times a week after cleansing for hydration and skin nourishment. Adjust duration based on your skin's sensitivity.
