A rich serum featuring 3 unique retinoids in an advanced delivery system for optimized skin penetration. The unique, in-house designed delivery system ensures maximum activity with minimal irritation. This serum was developed to boost the activity of other DELTA products to reduce the signs of aging, including wrinkling, fine lines, sagging and volume loss, as well as pigmentation concerns. It can be used in conjunction with any other DELTA product, and should be introduced slowly to retinol-naïve skin.

Instructions for use: Apply evenings, underneath moisturizer. As this product contains retinol, it is recommended to introduce the product slowly, and to use underneath HyD or HyR. Apply daily to improve results.
