"Using it instantly I notice that any shine on my skin is nicely mattified. As the day goes on I have noticed a huge difference. My skin doesn't feel as oily or cakey as much as it used to and feels so much better than without it. It's helped control my blemishes as it helps keep the areas oil-free! Towards the very end of the day I do notice some shine, but noweher near as much as I usually have, and I wasn't expecting it to eliminate oil from appearing all day. This has become a must have product for me on a morning when applying my make-up, and I feel more confident knowing my skin won't appear as shiny as it normally does during the day!"
