I almost didn't bother to try this product since I've tried all the others on the market, unsuccessfully. I should have know that PC's would be better. I apply it after my sunscreen and before powdering, and it works nearly all day. I do use oil blotting papers in the middle of the day, but I only need 1 2, versus 3 4 every couple hours as I did before using this product. It may not stop all oil all day (come on, I think that would be impossible) but it's a great way to keep down the shine! What makes this product unique? Paula's Choice Shine Stopper Instant Matte Finish is clinically proven to keep skin perfectly matte for at least 6 hours. Its unique MICROSPONGE® Technology works invisibly to keep oily shine in check while minimizing the appearance of pores. The luxurious formula dries to a silky soft, powder like finish that smoothes out minor skin imperfections—your makeup will look better and last longer than ever! This product is 100% fragrance and colorant free. Who is this product for? Anyone with oily skin (or oily areas) who wants to maintain a fresh, matte complexion. Shine Stopper is perfect for blackhead and blemish prone skin; ideal for combination skin with an oily t zone (forehead, nose, chin).
