Final answer:
To soften and moisturize the skin with the galvanic current, you would use a conductive gel.
Step-by-step explanation:
To soften and moisturize the skin with the galvanic current, you would use a conductive gel. The galvanic current works by using a low-level electrical current to stimulate the skin and enhance the absorption of skincare products. The conductive gel, which contains ions, helps to create a conductive pathway for the electrical current, making it easier for the current to penetrate the skin. This process helps to increase hydration and improve the texture and appearance of the skin.
