...and smells good too!
This lotion seems to be making my crepe skin kinda disappear?? It is so moisturizing & the scent is heavenly. I have used it on my face but it was a little much so I had to put it on while my skin was wet with water. That seemed to do the trick. In Colorado your skin can get super dry & this product seems to replenish softness & moisture.
