I try to scrape as much foundation off brush as I can before applying. I notice though always with a dark colour once foundation is applied and cured and Im onto colour by the time I have done the 1st hand and away to cure, the 1st 3-4 fingers I have painted the colour has disappeared from free edge!!!! I then put some more on............I take it is my foundation still too thick? I dry brush after curing foundation also!
