It's a watery like toner consistency. On the skin it feel lightweight. Only downside is the really strong tea tree scent, which you need to get used to it. I like it, because it helped my skin to become clearer. My blemishes, small pimples and even milia reduced. I also experience slightly more even skin surface without too many bumps. This can also control sebum a bit. Even though it has alcohol in it, it was still gentle enough for my sensitive and irritated skin. It also calms the skin a bit. Really like it and would recommend.
