This Gentle Retinol Complex is the first low-dose retinoid which is formulated for redness prone and sensitive skin. This gentle Retinol formula contains a combination of ceramide, fatty acids and cholesterol which help nourish and fortify the skin’s natural moisture lipids. This unique silicone-based vehicle is fragrance-free and preservative-free which improves retinoid tolerance by sensitive skin. The gentle formula allows the skin to acclimate gently to retinols with no irritation or dryness. This Gentle Retinol Complex should be used at night only. Use twice a week and as tolerated, increase to every other night.
