1. Microdermabrasion is to remove the cuticle of epidermis, stimulate the regeneration of keratinocytes and collagen, and improve the regeneration ability and skin quality of skin, thus achieving the purpose of improving skin relaxation and removing fine lines.

2. The principle of microcrystal grinding technology is that tiny alumina polygonal crystals (referred to as microcrystals) impact on the uneven skin scar surface under the guidance of vacuum closed system, making the scar smooth. Because microcrystalline particles are fine, they can act on the skin surface evenly. When they rub against scars and other tissues, their surfaces can be bonded with the rubbed tissue fragments and tissue fluid, which makes the original edges and corners of the crystal dull and the skin smooth and flat. At the same time, microcrystalline grinding can also stimulate blood and lymphatic circulation, accelerate tissue metabolism, promote pigment absorption, collagen and elastic fiber regeneration, and accelerate skin recovery.
