Fuctions: 1.Negative ions cleanse thoroughly the proes. Blockage of pores is the maincause of dilatation and roughage of the pores and darkening of skin and prevents assimilation of nutrients into dermal cells.The first step in skin care-cleansing is most important. Most cleansing products can only remove dust on skin surface and are powerless to clean the dirt and grease deep down in the pores. The highly energized negative ions emitted form the product can soften the dirt deep down in the pores and make the pores free of blockage. 2.Positive ions cause deep down infusion of nutrients. Assimilation function of fatigued skin and aging cells is remarkably reduced causing the essential components of skin care products pile up on skin surface and unable actually nourish the dermis dells. Skin is devoid of luster when the cells are undernourished. The positive ions can induce nutrients to penetrate deep into the skin, facilitate the cells, assimilation of water and nutrients causing the whitening factors and nutrients enter the skin, retain the nutrients making the skin lustrous, lighter in color and invigorated. 3. Infrared rays promotes metabolism. Dryness, pollution and fatigue cause over-strsess of the skin and precipitation of melanin, piling up of toxins causing the skin lusterless, darkening in color, formation of freckles, brownish plaques, etc. Safe warming up by infrared rays causes free circulation of the capillaries, acceleration of metabolism, expulsion of toxins, prophylaxis against aging of the cells and skin and forming of wrinkles and blemishes. 4.Physical vibration massages the skin. Gentle vibration produced by safe and weak electric current massages the skin through stimulation of outpoints, constrition of pores, cohering the interstitial molecules between the cells,tightening of the epidermis and dermis, hence increasing elasticity of the skin, slowing down aging and wrinkle formation.
