I've used for one week so far both AM/PM. Hot , humid weather in UK this week (70,% humidity), takes its toll on my dehydrated skin. This serum feel more like a luxury treatment cream. Smooth whipped texture, easily absorbed and 24 hour hydration. Packed with CeraVe 3 essential ceramides, Vitamin B5 and Hyaluronic Acid to deliver good results on short time. I personally Apply 3 pumps on slightly damp skin face, neck and collar bone part of chest/decollete immediately after cleansing. After a week I only needed two full pumps to cover same area. I found using CeraVe Daily moisturising AM Spf50 was a powerful pairing. My skin looks good, foundation glowing and no tightness, irritation or stickiness. #skincarebag #unboxing
