When it says flawless it means it. Simply apply to the face like you would a normal primer. Then apply your top layer be it foundation or CC cream. I can assure you that you can see and feel the difference. Flawless works it magic to give you a smooth and even finish. Not only does it help the foundation sit better it also helps it hold better. Now that I have used this product I wouldn't be without it. You cover your whole face with only one pump, so don't let the size of the bottle put you
off it really does go a long way.
