I have the same issue with MAC foundations they are easy to apply, it's just the shades I don't like. They're either for very pale girls or really dark girls..the colors inbetween have pink undertones which look grey after the make-up is complete =(
Try a concealer (cream) by Makeup Forever it's high in pigment and "set" u're concealer too with pressed powder for the extra lasting power! I suggest that u both try out Bobbi Brown foundation sticks..they'll give u the complete full coverage and hide all blemishes too! PM me for anymore information...
