What is the difference between body lotion, body cream, and body butter?

okay so in order from least moisturizing to most moisturizing it is lotion, cream, butter (just like you had it). body lotion is kind of ... greasy (for lack of a better word) or not as thick. body butter is really thick, and body cream is in the middle (i prefer body cream). i think lotion is for people who don't really have dry skin but use lotion just to make sure it stays moisturized. body cream is for people who have dry skin, but its not terrible just a little dry now and then. and body butter is for people who have reallyyyyy dry skin. what i do sometimes is use body lotion in summer, body cream in spring and fall, and body butter in winter. hope i helped!! xoxoxoxo
