couvre is hard to apply. Since it is a paste...you will need to wet the sponge and uniformly spread the paste on it and apply on your head.
I have found out that you need lots of couvre to cover up, since a tiny amount is not enough and usually rubs of at one "spot".
So you may have to rub it off your hand to make that distinguished couvre spot less visible.:x
Waste of money according to my opinion. I have ordered dermmatch..lets see how that goes!
