You can't even tell I used any from the bottle because a VERY LITTLE goes a long ways! So happy :) This really works well on removing many things from skin tags, to difficult pimples that won't go away and allot more

Also, don't start with this strength

I do this process once a week & am happy with it

You want to begin application on your forehead and then lower cheekbones/ upper jaw line (where the skin is thicker and less sensitive) and then work your way to the rest of your face applying the acid to the most sensitive areas, last

It does sting but is not unbearable

Initially, I planned to leave it on for 1-2 minutes as I have sensitive and very fair skin, but kept a close eye on it and left it on for a total of 5 minutes and then rinsed it off with a ton of cool water
