A skin primer makes a huge difference in a woman’s skin tone, point blank. Whenever I do makeup for a client or a special night out for myself, I do not approach a face without first adding a skin primer. And I will admit to being a “primer snob” in thinking that I should only use a more expensive brand name because I’ve been burned in the past with drugstore ones. But not anymore, thanks to Hard Candy’s Sheer Envy Skin Perfecting Primer ($8).
