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.

Very moisturizing with a great vanilla scent
I love this body oil. Very hydrating and smells amazing. It has replaced the original Palmer’s cocoa butter, body oil for me just because I like the smell better. It leaves my skin looking glowy and feels so smooth. I smell like vanilla all day. I like the pump top. It is easier to apply. Very silky consistency

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.

JUST BUY IT!!! Finally found what I was looking for
This is the first time I have ever written a review - THATS how good this product is!!
It smells like vanilla bean ice cream, it is so deliciously sweet and fragrant. I have been searching for something that leaves a strong yet natural scent on the skin and this is it.
It makes me feel like a sweet and soft ethereal fairy princess and is so so so moisturizing on the skin. My bf loves it and has pointed out multiple times how soft my skin is just from a few uses
I use it right out of the shower while my skin is still a bit wet. It is lightweight enough where it dries quickly enough for me to put my pajamas on without greasy-ness. I'm at work the morning after and can still lightly smell it on myself
If you're looking for a sign - this is it - JUST BUY IT!!! :)

Light, Hydrating, and Non-Greasy — Perfect Everyday Body Oil
I purchased this body oil a little over a week ago, and overall, I have nothing but positive things to say about the product itself. The only complaint I have is with the packaging. When my order arrived, some of the oil had leaked in the box. The bottle doesn’t come with a separate cap—just a twist/lock feature that can easily come loose. Because of that, it must have unlocked during transit, causing a small amount of product loss. Luckily, it wasn’t bad enough for me to feel the need to return it.
As for the oil itself—it’s lovely. The scent is light and pleasant, nothing overpowering. While I don’t pick up a strong vanilla note once it’s on my skin, it has a smooth texture that absorbs quickly without leaving any greasy residue. It’s very hydrating, and the bottle size feels generous for the price.
If you’re looking for something heavily fragranced, this might not be the one for you, but it’s perfect as a layering oil or for anyone who wants a subtle, nourishing glow. Highly recommend!
