I've been using this product for over a year and it is a great addition to an acne treatment regimen. It seals in active ingredients and forms a protective barrier to keep out pore-clogging elements. For a long time I felt like I was stuck using foundations and concealers that were made to help treat acne because anything else would make me break out. But now that I use this product after my acne-treatment products and before I apply make-up, I can use any type of foundation and the protection cream gives me a smooth, even canvas for applying my foundation and concealer. My make-up looks smoother, more even and natural and I don't have to worry about the foundation making me break out.
