Moisturizer, as we mentioned, is the first step in any makeup application. It creates a nice, even palette for your foundation. If you have oily skin, you might want to apply some astringent before your oil-free moisturizer. Dry-skinned ladies, of course, should be using a more intense moisturizer. And don't forget your under-eye cream. Regardless of your skin type, wait about 10 minutes before the next step -- you want the moisturizer to fully soak in before you apply any makeup.
Speaking of the next step -- if your skin has any texture issues, you might want to consider using a primer after you've moisturized your face. Some women claim that primer is a do-or-die item, but it's really most useful for people with very oily skin or heavy scarring says makeup artist Molly Stern.
