Safe and easy to use due to its skin-friendly formula. The electrode gel is odorless and hypoallergenic, making it suitable for all skin types. The gel is suitable for all types of EMS pads, including snap and pigtail electrode pads in various shapes. High Conductivity: With the unique formula, glycerol makes skin hydrated and pads sticky for better electrical transmission throughout use. Our conductive gel for TENS unit electrodes is designed to improve the conductivity by using a unique and highly conductive solution that facilitates better skin-to-device contact Multiple applications: It is suitable for a wide variety of applications besides TENS pain therapy. It can also be used for Ultrasound devices, Microcurrent devices, Muscle stimulators, and Ab belts Application for use with adhesive electrode pads: Apply a few drops of the gel to the sticky surface of the electrodes and spread it evenly with your finger. Let it absorb for a moment, then place the electrode on the desired body part.This water-based gel with high moisture is easy to clean and remove from the skin with a wipe. Replacing layers of air with its aqueous solution, the gel removes any barriers that may reduce the TENS unit's effectiveness. It can also help to increase the lifespan of the electrode pads
