Right when you take some of the mattifier out of the bottle you will notice that it has the sent of green tea and mint . its effects are sudden and barely noticeable, but it does work. If you read the description of the product you should know that it can also be used as primer so i tested it out by applying it on my eye lids before my makeup and it worked for a bout an hour or so but i really feel it would be worth the cost to just buy a primer you'd get better use out of your money .
