FAQ: How do I know if the product I buy on Walmart is authentic? Only purchase CeraVe branded items that are designated as "Sold and shipped by Walmart.com.” Products sold by distributors or third parties are not guaranteed to be authentic. This designation is listed on the item’s product page under the “Add to cart” button. Developed with dermatologists, CeraVe Skin Renewing Cream Serum is a gentle yet effective daily retinol cream that provides a variety of anti-aging benefits. Ideal for all skin types, the non-comedogenic formula reduces the appearance of fine lines and wrinkles as it improves the skin’s texture and radiance. Unlike many retinols, which can be harsh and irritating to skin, this innovative complex contains encapsulated retinol which stabilizes and delivers the retinol throughout the skin gradually over time, so it helps minimize irritation. Enhanced with moisture-rich hyaluronic acid, soothing niacinamide and three essential ceramides that restore the skin barrier and help retain hydration, this retinol serum also features patented time-release MVE Delivery Technology for around-the-clock nourishment.
