Oily and can burn
Does make skin smooth and can help with dry skin, but that’s because it leaves an oil on the skin. It can be helped by drying with a towel. It can burn sensitive skin until rinsed. I’ve used it for a couple weeks now. Smells good, but I don’t like the oily texture it leaves and it could moisturize the skin better.

ALL OVER BODY SCRUB GREATNESS
I really like this scrub I have sensitive skin and bearly can use different scents on it but baby my skin feels AMAZING after first I wash with dove sensitive skin bar soap then rinse and massage this into my skin starting with my elbows then my butt then my tights and legs and feet I used this 3 times a week and I love it I ordered one and it got lost before it got delivered so before cancel it I ordered another one because it said that it helps with cellulite they showed up at the same time so I kept them both I never experienced the greasy feeling I felt moisturized and soft smooth skin and I also see a little bit of a difference in my cellulite after my third shower and neither one of my lids wasn’t cracked and I love that it has a plastic seal when you twist the lid off and it has a light lemon scent I love this product I added to my shower routine now it’s one of my favorites and a must have will be purchasing more as long as it’s not discontinued or the product mix doesn’t change. Never tried it on my face.
