To get a radiant complexion, there are a number of simple things to try, from diet to sleep to products. One easy change to try comes from Elaine Sauer, of N.Y.C.'s Red Door Spa. She recommends washing the face with a cleansing oil. "It works wonders to lubricate the skin, lightly exfoliate by using cleansing massaging and also nourish the skin," she says. Plus, they work for all skin types.
