Hydrinity CELTHERA Advanced Overnight Repair Cream is a peptide-rich night cream built around three targeted technologies that work together while you sleep to visibly firm, smooth, and restore skin at a cellular level. The formula centers on ExoEGF Technology, a biomimetic exosome system that delivers oligopeptide-1 deep into the skin to support collagen and elastin production, paired with a sunflower sprout-derived NAD+ booster and Centella asiatica secretomes that address the biological factors behind visible aging. A five-ceramide complex, squalane, niacinamide, and hyaluronic acid round out the formula to reinforce the skin barrier overnight.
