Moisturized heels out of the box
Color: Fuzzy Lilac Purple, Size: Regular
Work without adding anything to your feet, but there are extra nice if you wanted to add a moisturizer to you heel and not get it all over your socks. Worth the money!

I even used it on my face
Color: Bronze Gold
I purchased this shimmer oil to use on my legs when I’m wearing a summer slip dress. I’m not always fond of how my legs look, but once I smoothed this over my lightly tanned skin—wow, what a difference. The glow is subtle yet so flattering. One day I forgot my highlighter, so I lightly dabbed this over my contour, brushed a tiny bit over my lips with chapstick on top, and it looked amazing. Now it’s my go-to beach look: a little shimmer on my arms and legs, a tad on my lips, a soft sweep across my eyelids, and a touch on my cheekbones. It gives me that effortless, radiant vibe that’s perfect for summer.

Smells like crayons
Color: Bronze Gold
Stinks. Smells like covering yourself in melted crayons. Very cheap smelling. Left it on ny skin for an hour, then wiped with a rag and it immediately came right off. You're better off just getting bronzer.
