Even if it dries out, u can smudge it and if it's lighter than u're skintone it can turn-out to look gray! So it's best to use u're concealer over u're foundation in downward and outward strokes (fingers, sponge or brush) then with a conceaer brush dab u're concealer on u're blemishes..this will give u're makeup a great "finish" once u've applied u're loose powder and dusted it off with a large brush!
