My experience with DermaTend has been a guessing game. If you order this product, throw the instructions that come with the product in the garbage. This company keeps changing the amount of time to leave the product on. I have found best results can be expected after a hot shower before you go to bed. Scratch mole(s) with emery board and sterilized pin, apply DermaTend to cover mole, apply band-aid and rinse off in morning. Let dry to form scab. Let scab fall off naturally. Apply neosporin. ☠
