Super skin savior
Serums absorb deeper into skin than moisturizers. With serums you get a high concentration of active ingredients. Serums are made of smaller molecules so they are able to penetrate skin quickly and deeply. Normally the largest ingredient of a moisturizer is aqua (water) so you can never get the super concentrated active ingredients you get with a serum. When you apply Face it serum, just a few drops is enough. The serum will spread itself. Remember to apply on damp skin.
