I couldn't say exactly how much I used, cause I take the stuff internally as well. I just used a drop a day. A 1oz bottle will last you a long time if you are only using it externally. The spot where the mole was has left a scar. I don't know if it will fade in time. I hope so. I have been painting it with Lugols every few days to help the scar fade and also put VCO on it daily. The scar is still an improvement over the mole, but I would still like it to fade.
