Packed with three essential ceramides, hyaluronic acid,

and vitamin B5, CeraVe's serum locks in moisture and smooths the skin like whoa. The formula provides 24 hours of hydration, which is a big plus since you won't have to reapply.

What a reviewer says: "The product itself is fantastic. Holy grail status. It's not a 'serum' the way we traditionally think of serum—more of a gel-like moisturizer. It's white and creamy, rather than watery and translucent/transparent. It doesn't break me out, so it's good for sensitive skin, and, as with most CeraVe products, it's fragrance-free. There basically is no scent, which is a huge bonus in my book. I finally found something to mix with my nightly high-end serum, and it’s cut my skincare spending in half."
