I'm going to be doing a review/comparison of the Face and Body foundations from MAC and Make Up For Ever. They have some similarities and some differences. Face and Body foundations are light weight liquid foundations that are intended for the face and body (obviously). They tend to be water resistant and silicone based. The coverage is very sheer but buildable because of the silicone allows the foundation to completely set and more layers can be added on top without getting caky. The finish is dewy or satin if you decide to powder.
