Using a facial moisturizer should be a no-brainer. Even if you're not concerned with wrinkles
or dark spots
(and you must be one in a million), it's essential to keep your skin hydrated. The outermost layer of skin — called the lipid layer, barrier layer, or stratum corneum — needs to be moisturized to stay healthy.
"A healthy lipid barrier will protect itself again irritants and UV damage," says New York City dermatologist Jeannette Graf, M.D. It keeps the good things (like water and nutrients) in, and the environmental stressors out. Eating a well-balanced diet and drinking plenty of water will help, but it's also important to use a facial moisturizer morning and night.
Fortunately, many dermatologist-recommended moisturizers can be found at your local drugstore for less than $15 >>
