Good lotion, doesn't smell great.
Lotion feels nice on the skin and is fairly moisturizing. The scent leaves something to be desired. I was hoping it would smell more beachy or vacation-esque, but the scent is light and slightly pungent.

No bad tanning lotion
I love how hydrating this product is but I’m not sure if it really helped with my tan. It does have a very subtle smell and the ingredients seem to be relatively good

Great product!
Scent: Unscented
AMAZING!!! I use it every day, and I don't even need to use makeup, it keeps my skin super soft and keeps dirt from entering my pores!
