Hydroxyl-hydroxide refers to the conversion of purified water into hydroxide-ion water, which produces H2 fine molecules on the surface of the skin and rapidly penetrates the water molecules into the skin to achieve the efficacy of tender and white.

Through the formation of a vacuum circuit, the tiny bubbles and nutrient solution are fully combined. Through a special design of spiral suction directly acting on the skin surface, the instrument produces thousands of bubbles. Small bubbles contact the skin with vibration, taking away the excess cuticle so that the skin returns to normal layer thickness. Together with the original solution, this improves, cleans, whitens, tones, exfoliates, and removes blackheads from oily skin, offering multi-layer benefits.
