You can buy liquid Ivermectin injectable which is already at 1%, and just put it on you face at night. I just got a 250ml bottle for $68, at a feed store. Another solution that works is borax mixed with Hydrogen peroxide. You have to dilute the 3% HP to 1% so 2 parts water 1 part HP. Add borax until it stops dissolving into the liquid and you see it settling to the bottom. Add small amounts until you see it no dissolving not the liquid anymore.
