Regenerist Daily Regenerating Serum, our most concentrated formula, was developed for women who are looking for maximum Regenerist effect, and its new advanced formula now contains another peptide - Carnosine - for additional anti-oxidant power, as well as pentapeptide KTTKS - the hottest anti-ageing ingredient! The serum beautifully regenerates skin cells in the outer layer, so skin looks and feels like new! It performs as a moisturiser, providing hydration for immediate and long term results. The serum has a velvety-smooth, non-greasy feel to immediately improve the look of skin. The serum can be used in the morning as a base under makeup, and along with the Rehydrating Lotion with UVA+UVB Protection if desired. It can also be used at night, followed by the Replenishing Cream. For best results, use the serum every day.
