Nice
Size: 5.1 Fl Oz (Pack of 1), Size: 5.1 Fl Oz (Pack of 1)
I will give this product, a four out of five because it is really good. It has a lock on it so that it won’t come out whenever you don’t need it to it smells like coconuts, which is nice and it is shiny but as you can see, unless you maybe have a light up to it you can’t see it that well, but it’s very soothing on the skin and it does darken it a little bit, which gives it that bronze gold look that I was looking for which made me really happy but I just wish it was a little darker and glittery but other than that overall it’s a good product and it does give you that shine that you need and it lasts all day

MY NEW FAV!!!!
Size: 5.1 Fl Oz (Pack of 1)
Palmer's Cocoa Butter Formula Shimmer Body Oil is hands down my new favorite! It leaves my skin feeling soft, hydrated, and with a beautiful shimmer that looks natural and radiant. The scent is amazing, and it absorbs quickly without feeling greasy. I’ve tried other body oils, but nothing compares to this one, don’t give me anything else! This is the best, and I’ll keep buying it again and again.

Moisturizes with simmer!
Size: 5.1 Fl Oz (Pack of 1)
Not a lot of shimmer, which is a good thing when putting it on, thought it was going to be overwhelming from the bottle, but not. Moisturizes all day. Smell is strong in the beginning but dissipates after a while.

I caught a vibe!
Size: 5.1 Fl Oz (Pack of 1)
Ok, so I love this oil. As a pool girlie I loved laying out and lathering this on. The smell is simply fantastic! The bottle actually caught thy eye of a few sparkle girlies too by the pool and wanted to know where I got it. For a second I felt cool so, it’s five stars for me for setting a vibe and being the cool girl at the pool, with the sparkle and the great smelling skin!
