INSTRUCTIONS FOR USE Apply to your face at night once a week or as recommended by your specialist, massaging in gently in a circular motion for one minute to help remove dead skin cells and facilitate the penetration of the active ingredients. Leave on overnight and rinse off with warm water. PRECAUTIONS AND WARNINGS Avoid direct contact with eyes and mucous membranes. Slight stinging is normal during initial applications. If irritation persists, discontinue application. Do not apply to open wounds or inflamed areas.
