Night is the best time to provide the skin with all of the necessary nutrients included in the serum. During this time the skin absorbs and allows the active ingredients to penetrate deep into the skin: while skin rests, cutaneous microcirculation is activated and facilitates the penetration and dispersion of active ingredients. Regenerating functions are optimized because biological energy is more readily available for skin cells at night. HELPS: - Nighttime repair: cellular life complex with 56 active ingredients is enriched in ATP, a biological molecule charged with energy: “to awaken the youth potential of cells that have become lethargic over time” - Enhance the skin’s appearance during the day, visibly rejuvenating and improving firmness. Day after day, the face appears more youthful, firmer and smoother.
