You only need a facial primer if you have very oily skin. If you have very oily skin and your makeup foundation streaks- we recommend omitting the moisturizer (step 4) in your skin care routine. Wash your face, apply the eye cream to the eye area, then apply the step 3 treatment product found in your skin care regimen. After the step 3 treatment product, apply your facial primer. Cover with sunscreen and facial foundation. We recommend that you consider using a tinted sunscreen as your facial foundation. This will give you fewer steps and help prevent streaking of makeup.
