Quality Body Oil
I love the ingredients in this and that it’s none comedogenic for my bacne. The spray bottle is not easy to apply since it’s messy so I put the contents into a glass pump bottle and leave the excess in the original bottle in the bathroom for my oil cleansing/make up removal or to spray on wet skin post shower. Wet skin stays a little oily so I tend to use a body powder but dry skin I can get away without it though it will leave a sheen (be careful with silk). It lasts me about 3 months and leaves my skin moisturized and soft

Not a spray; more like a stream
I purchased the body oil for my husband because he has eczema and needed something for moisture. I think I actually use it more than he does. The body oil comes in a spray bottle with a pump, but be prepared, it doesn't "spray" out of the nozzle. It's more like a stream. One good thing is that is doesn't run down your leg before you're able to wipe it around. The scent is not nice, but it does give you moisture. I had no irritation using it.

Really helps dry skin
Great product. I use after shower. After rubbing it in my skin it seems to soak in quickly so not greasy on clothes. I have not had the dry skin problems usually do in winter since using this product!

Allergic
I would not say don’t use this product, but for me, after the 2nd use, I noticed bumps on my forearm, rough skin on the back of my elbows. So to say, I am having an allergic reaction. Some people may not, but I am. The smell is bad when you open the bottle, but dissipates after you put it on and it sits for a while. I can’t use because of highly sensitive eczema, maybe someone else can.
