Fantastic value - look at how big the bottle is in the photo! I thought the snail would have made the essence heavy, but I'm happy I took the chance because it is very light indeed! There is no oily sheen after I use it. I would describe the lightness of the essence similar to toner. It's a little bit heavier than toner but much lighter than other essences I've used in the past. I would definitely recommend this for people with oily skin!
