Review title is last 6-8 hours or more on normal skin [SEP] It definitely prolongs the use of makeup by at least 6-8 hours and you would not need to blot. I am on a skin treatment that causes my skin to become excessively oily.(no joke... my skin becomes so oily, i need 3-4 tissues to wipe the oil all off and immediately i am done wiping, the oil oozes out again) . My normally normal skin now oils-up to the point that I can scoop up oil in a spoon in an hour. Its so annoying. Nothing was working to keep the oil at bay when i was at work. My face would be so oily, I stopped using foundation and would have to rub my face down with a towel due to the oil. This kept my skin oil free for 6-8 hours, no blotting at all. but couldn't hold it back after the 8th hour. That was fine. When my skin returns to normal. I know this product should last 24 hours if not a week without blotting;... if you plan on keeping makeup on for a week straight.
