Our foundation primer is a light-weight emulsion of jojoba, sunflower seed oil, vitamin A, D and E. Cyclopentasiloxane is also used in the product as a silicone. This product is often used in most make-up, shampoos and conditioners. It reduces the visibility of the fine lines when used on your skin and when used in the hair, it provides a silky feel without weighing down the hair. Use over the moisturizer and under foundation. A pea-size amount is all that is needed for your entire face and neck area. LESS IS MORE with this product. The 1.2 oz pump will deliver about 200 applications.
