First, what is serum?

A serum is a skincare product you can apply to your skin after cleansing but before moisturizing with the intent of delivering powerful ingredients directly into the skin. Serum is particularly suited to this task because it is made up of smaller molecules that can penetrate deeply into the skin and deliver a very high concentration of active ingredients. This makes them a great tool for targeting specific skincare concerns, like wrinkle and other signs of aging.

Is serum a moisturizer?

Yes and no. Serums can be chock-full of moisturizing ingredients like hyaluronic to help skin retain moisture. But, that doesn't make them moisturizers in the traditional sense. Face lotions and creams are richer and create a barrier on top of the skin to keep all that good stuff in. -ITG
