Concentrated customisable night-time Retinol treatment cream accelerates skin renewal and reduces the appearance of skin ageing. Active 0.5% microencapsulated pure Retinol helps increase cell turnover. Powerful peptides and antioxidant Vitamin C help reduce uneven skin tone and discoloration. Formulated with a clinically-proven bioenergised Copper amino acid complex shown to visibly reduce wrinkles and improve skin firmness. Ceramides and active Polysaccharides hydrate and prevent water loss in the skin, helping soften fine lines. Includes a moisturising Buffer Cream to help acclimate skin to this highly-active form of Retinol. How to use: Use at night when cell renewal is at its prime. This product is highly-active, and we recommend the following regimen to help your skin acclimate: Pre-Conditioning Phase 1. Mix 1 part Overnight Retinol Repair with 3 parts Buffer Cream and apply to cleansed skin as a last step at night. For more sensitive skin, apply mixture on alternate nights. 2. You may increase the ratio of Overnight Retinol Repair to Buffer Cream as your skin adjusts. 3. If you run out of Buffer Cream prior to your skin acclimating, you may substitute it with your prescribed Dermalogica Moisturizer. Ongoing Treatment Once your skin is acclimated, you may use Overnight Retinol Repair alone, prior to or mixed with your prescribed Dermalogica moisturizer. Overnight Retinol Repair can be incorporated into any Dermalogica regimen. For best results, we recommend using Overnight Retinol Repair and other Dermalogica treatment products on alternate evenings. For the eye area, use Age Reversal Eye Complex.
