About Electroporation Electroporation is a technique used in skincare devices that utilizes special electrical pulses. It is generally said to be able to address ingredients that are difficult to handle with iontophoresis or ultrasonic introduction. Heating Effect By heating the head up to 40°C, it activates skin cells and creates a skin condition that allows beauty ingredients to penetrate easily. Cooling Effect Cools down to -15°C. Treatments at -5°C to -10°C cause vasoconstriction. By allowing the serum to be introduced only into the skin without being absorbed into the capillaries, the introduction effect is increased. Since it is a new product, distilled water is initially added for use. It seems that there are many inferior products and imitations. Many inexpensive products have a low-end 2.25Kg system for the core of the machine. Because the system itself is different, many products with the same exterior but completely different internal systems are circulating.
