Answer: As far as I know, Ems mode is a technique to achieve the effect of exercise and shaping by stimulating muscle contraction with electric current. Essence usually refers to products with high concentration of active ingredients in skin care products to provide additional nourishing and repairing effects. From this point of view, Yixin is not suitable for direct use in Ems mode.

Ems mode mainly stimulates muscle contraction through electric current to achieve exercise effect, and its essence is more about nourishing and repairing the surface layer of skin. There are obvious differences between them in principle. Applying the essence directly to Ems mode may not have the expected effect.

Essence usually contains high concentration of effective components, such as vitamin C, hyaluronic acid, etc. Direct contact with current may cause irritation or allergic reaction. When the current passes through the skin, it will form a closed loop, and the depth of penetration into the skin is shallow, so the effective components in the essence may not be fully absorbed and utilized.

Ems mode is generally combined with specific conductive adhesive or skin moisturizing spray to improve the current conduction effect. The formulas and uses of these products are different from the essence. Therefore, when using Ems mode, we should choose products specially designed for this technology to ensure the best exercise and shaping effect.

According to my personal understanding and clinical experience, I don't think Ems mode is suitable for using essence directly. If you want to improve your skin condition through skin care products, you can choose other products that suit your skin needs. Remember, before using any new product, it is best to consult professionals to ensure safety and effectiveness.
