I use lotion everyday because my skin dries out so easily, but I have several different brands and scents, so I change it up every day so I don't use up any one of them too quickly. That way I always have them for a special occasion!
I used to use it only on a special occasion, then I realized it would go bad before I used it all. I thought to myself, why aren't I using this everyday?? It's not like I can't buy more!! So now I use it everyday!!!
