As the cartridge moves up and down on the skin, the microneedles penetrate the epidermis, creating thousands of fine channels. Simultaneously, the essence is automatically delivered from the applicator, allowing it to reach the deeper layers of the skin with an absorption rate over 90% higher than manual application. The microneedles also initiate rapid skin tissue repair, stimulating cell regeneration and enhancing the skin’s vitality and elasticity, effectively doubling the healing benefits. To accommodate essences of varying consistencies, the device features three customizable liquid output levels. Users can control the liquid flow with the speed gear: higher settings increase the frequency of liquid output, while lower settings decrease it.
