1、The diameter of skin pore is about 0.02‑0.05mm which is easy for water molecule to enter in. 2、With the help of the spray function, the water molecules can be divided into smaller particles with diameters 0.3‑0.5um(about 0.0003‑0.0005mm). 3、Microdermabrasion, base on the friction and vacuum principle, act on the skin and exfoliate the aging cuticle of the upper layer. Skin rejuvenation technology. 4、Could help to recuperate the skin texture, rebuild a healthy skin, improve the aging cuticle, shallow the pigment, shrink pores, eliminate the acne scar etc. 5、Accompany with proper skin caring process could make the skin tender and full of elasticity. Condition: 100% Brand New Item Type: Microdermabrasion Machine Material: ABS Service Power: 10.5W Efficacy: Microdermabrasion, water and oxygen replenishment Purpose of conduit: 1. When using the machine, the filter is connected to the interface, and the filter is connected with one end of the catheter, and the rod is connected with the other end 2. When using oxygen injector, one end of the catheter is connected to the oxygen injector interface, and the other end of the catheter is connected to an oxygen injector nozzle Purpose of Filter: When it is absorbed, more or less some products will be absorbed into the internal of the instrument, so a filter is needed to filter Working Principle: Microdermabrasion tube inlaid diamonds have different degree of thickness of fine gold stone particles, by the way back and forth friction, and cooperate with the vacuum suction grip strength, a way of non-invasive, physical dead cells in the epidermis, old cutin, promote skin collagen hyperplasia. Note: Please note that red, green, yellow filter will be sent randomly. 1 x Host 1 x Set of Spray Tool  (spray tool x 1, dropper x 1, wrench x 1, instruction x 1) 1 x Power Cord 1 x Adapter 1 x Host Instruction 3 x Microdermabrasion Rod 9 x Microdermabrasion Heads 1 x Bag of Sponge Sheet 1 x Filter 1 x Catheter
