  Hyaluronic acid with large molecular weight（range:1800000~2200000）form a ventilate thin film on skin surface, which smooth and moisten skin, separate external bacteria, dust and ultraviolet to protect skin.
  Hyaluronic acid with medium molecular weight（range:1000000~1800000）can firm and moisten skin for a long time.
  Hyaluronic acid with low molecular weight（range:400000~1000000）penetrate into dermis, expand blood capillary slightly, increase blood circulation, improve intermediary metabolism, promote skin alimentation, remove wrinkles strongly, increase skin elasticity, and delay skin ageing.
