After cleansing in the evening, smooth a pea-sized amount of Sleep Glycolic onto the face, neck and décolletage – avoiding the eye area. Some slight skin tingling is normal.
Follow with other serums and night moisturiser. Leave on overnight. As Sleep Glycolic is directly active on your skin, it should be the second step in your evening skincare routine (after cleansing). Layer all other serums and moisturisers on top.
Always wear sunscreen the next day after using Sleep Glycolic. Patch testing prior to use is advised.
