The lotion moisturizes the skin's surface with AMP and several other moisturizing ingredients. Since it is a lotion, it can be easily applied to your face and entire body. The milk contains a moderate amount of oil, in addition to AMP and several other moisturizers, which enables it to be absorbed easily by somewhat dry skin. Finally, the cream contains oil along with AMP and several other moisturizers, which helps retain moisture for dry skin. It goes on comfortably, and does not feel heavy even though it is a cream, making it easy to apply to the whole body.
Each of these product types can be used for the whole body, so choose the one that works best for you.
