Apply evenly over the face and neck avoiding the eye contour. Start the application on the T-zone, especially if you have combination skin. Leave it to act for 1 to 2 minutes or from the intense tingling sensation, then rinse thoroughly with water. Use Purify Masque 10 once or twice a week.Tips: Can also be used for blemishes on the back and shoulders, where the skin is thicker. As Purify Masque 10 has an exfoliating action on your skin, do not combine it with an abrasive mechanical scrub!Cautions: Purify Masque contains Glycolic Acid, be sure to use a sunscreen such as Sunlight Screen 50+ every day. Should not be used just before strong exposure to the sun (beach, mountain, prolonged outdoor activities, etc.). If your skin is damaged, if you have just been waxed, or if you have had a mechanical exfoliation, wait 24 hours before using Purify Masque. Be careful with the application time: leaving on for too long could sensitize your skin too intensely. Rinse the mask off immediately in the event of discomfort (itching, intense tingling, sensation of heat, etc.). Avoid contact with eyes, otherwise rinse thoroughly with water. Not suitable for sensitive, damaged, irritated or problem skin. Not recommended for pregnant or breastfeeding women.
