CeraVe Skin Renewing Retinol Serum is a gentle, dermatologist-developed anti-aging serum that reduces fine lines, improves texture, and brightens skin using encapsulated retinol for slow release, plus hyaluronic acid for hydration, niacinamide for soothing, and three essential ceramides to repair the skin barrier. It’s fragrance-free, non-comedogenic, and suitable for all skin types, but always use with sunscreen during the day due to retinol’s sun-sensitizing effects, applying nightly for best results as your skin builds tolerance.
