An LED mole pen is a device that is designed to remove moles, skin tags, and other blemishes using a combination of electrical currents and LED light. The device typically consists of a pen-shaped tool that emits a low-level electrical current and a small LED light that helps to illuminate the affected area.

To use an LED mole pen, you typically start by cleaning the affected area and then using the pen to apply a low-level electrical current to the mole or blemish. The current is intended to break up the cells within the mole or blemish, causing it to eventually fall off. The LED light helps to illuminate the area and make it easier to see the mole or blemish.
