Just like cleansing and moisturizing is a part of preparing skin before makeup, primer is an essential step before applying makeup. It prepares your skin to ensure a long-lasting application. Color Studio Pro Primer is an oil-free formula, which has a super-light consistency. This added layer between your skin and makeup helps your makeup stay smooth and last longer. It reduces the appearances of visible pores and evens out skin tone. You can also apply it over makeup if not before and ensure extended wear.
