Step-by-step explanation:
An example of low level direct current used in facials is galvanic current. Galvanic current is a low-level direct current that is commonly used in facials to improve the appearance of the skin. It works by stimulating the muscles and increasing blood circulation, which can help reduce the appearance of wrinkles, fine lines, and acne.
During a galvanic facial, a positive electrode (anode) and a negative electrode (cathode) are used. The positive electrode is typically used for deep cleansing, while the negative electrode is used for nourishing and hydrating the skin. The galvanic current helps to draw impurities out of the skin and allows products to penetrate deeper into the skin.
Overall, galvanic current facials can improve the texture, tone, and overall appearance of the skin. They are often used in professional skincare treatments to achieve desired results.
