Base makeup is the very first step of your entire makeup schedule. Use a foundation that goes well with your complexion. A shade brighter than your original complexion is preferable. Dab it properly on your face with the help of a brush and then blend it properly. To conceal all the fine lines and dark circles proper application and blending is very necessary. This is your first step as a brighter base will help you to get an emerald look, which is desirable.
