I was DISAPPOINTED
I was very excited to try this bc of the shimmer and glow and bc I’m a vanilla scent girly and I was disappointed bc it didn’t smell anything like vanilla However, I like the smooth body gel feel it wasn’t heavy and thick so that was a plus for me My bottle wasn’t wrapped or taped to prevent leaking bc when I removed it from the package I could tell something happened because there was no leaking in the bag it was just on the top where you squeeze it and almost 2 inches was gone from the bottle so I was disappointed bc the bottle is small anyways and for the price I want a full bottle bc normally when I order lotions or body creams they’re packaged with some extra care and this package wasn’t 😔

Love this subtle shimmer rose bronze very moisturizing &thicker
Beautiful color shimmer & sleek shine. Can be subtle or apply more to get a oil look. Smells a little bit like coconut which I don't love if Im wearing perfume. Its a beautiful bronzey pink subtle shimmer. Not glitter & reapply to be a oiled goddess. Works perfectly on my light-med skin tone. Definitely a great summer find. And it is moisturizing & a pretty sheen.

Love the smell and great for my skin
This has become a permanent part of my shower routine. I use it right after I turn the water off while I am still wet, I cover my entire body from the neck down using about 8-10 pumps. I will wrap my body in a towel and finish getting ready (brush teeth, face moisturizer and blow drying hair) and then I will gently rub the towel everywhere incase there is any excess oil after it had the time to absorb into my skin. I dont think it leaves any greasiness at all, its really lightweight. What I love most of all is the smell though. A very nice, light, sweet vanilla smell lingers on your skin until your next shower. You have to put your nose pretty close to your skin to smell it so you wont be bothering anyone who had scent sensitivities. I have been using this for almost a year now and I still keep bringing my forearm to my nose to smell my skin because I love it so much. My skin has improved so much since I started using this.

A GREAT OIL FOR YOUR SKIN
I JUST REVIEWED THE LOTION WHICH I LOVED AND I ALSO LOVE THIS OIL. I THOUGHT THIS WAS A LITTLE BIT PRICEY BECAUSE THE BOTTLE IS A BIT SMALL HOWEVER YOU REALLY ONLY NEED A SMALL AMOUNT AS A LITTLE GOES A LONG WAY. IT ABSORBS INTO YOUR SKIN NICELY WITHOUT FEEL OVERLY GREASY AND IT LEAVES YOUR SKIN SOFT AND SMELLING VERY NICE. THE SMELL IS LOVELY BUT IT ISN'T A REAL STRONG SMELL AND THE VANILLA ISN'T OVERLY SWEET EITHER. IT IS THE PERFECT VANILLA. IT LEAVES YOUR SKIN REFRESHED AND I LOVE IT !! IT GOES GREAT WITH THE LOTION.

Worth it
Okay first night using and I’m in love. Smells amazing. I’m particular about my vanillas but this is light but strong. Doesn’t disappear right away sits on the skin nice and drifts on the air as a nice aroma. Dries down wonderfully too. I did have to use a few pumps to cover each part of my body but so worth it. It’s not greasy at all and gives a nice glow. Application was easy and I do feel moisturized. Looking for the lotion version now to layer over top it.
