New Product Alert: MAC Prep and Prime SPF 50

Primers are nothing new, but the SPF 50 sun-protection in this just-released MAC Cosmetics product stopped me in my tracks. Called Prep and Prime ($26.50), this multi-tasking potion acts as a moisturizer, a primer, and a sunscreen, so you can cut out a couple of steps.

All you need is a small amount, and it absorbs very quickly. Simply apply it after you wash your face and wait a couple of seconds before you begin your makeup routine. Another bonus: It contains oil-absorbing powder to help keep you looking matte all day.
