I don't have sensitive skin but this product made my skin burn like hell. No matter if I used it on my chin for spot treatment or under my eyes, the skin was very irritated, and red until the next morning even though I rinsed it off. Tried a couple of times, every time it was the same. As for making toner out of it- it didn't work for me either even with very hot water, the patches didn't ressolve even a bit. I think I might got defective item or something like that (the whole packaging was a bit sticky so maybe it wasn't sealed properly in the factory) either way if you're interested in this and have sensitive skin- watch out!
