The most potent form of vitamin C is a powder that’s mixed with a hyaluronic serum moments before use. Exponent makes it easy with a system that delivers exact doses in a handsome fluted canister. Be sure to mix it well, and don’t use it with oily products on top or underneath.

A blister pack holds 60 tablets of preservative-free, highly concentrated hyaluronic acid, the ingredient long admired for its ability to hydrate and plump skin and reduce wrinkle depth. Mix it with eight drops of liquid activator and slip it all over your face, neck, and chest.

The closest thing to playing professional facialist (or having Kate Hudson as your facialist). Depending on your skin sensitivity, mix a little or a lot of the vitamin C and antioxidant powder with water and apply with the included brush.

Pour the liquid base into the powdered vitamin C and shake, shake, shake. When topped with the vacuum pump, the serum stays fresh and active for one year. The resulting texture is a little sticky, but it’s supposed to be. Deal with it.

This intellectual skin-care product was created by a Nobel laureate, no less. Sir Fraser Stoddart found a way to encapsulate active ingredients so they maintain potency and reach the parts of the skin at the right time for maximum benefits. The single-dose sachets are biodegradable.

Skin-care obsessive? This mini refrigerator holds an impressive number of products, keeping them cool and fresh for as long as possible. Stash your jade roller or gua sha tool in there, too, for extra depuffing.
