LMW HA 100,000Da~500,000Da, generally used for oral administration. Small molecular HA in the human body can generate high molecular HA and play the role of high molecular HA.

Hyaluronic acid acts on the skin surface

Ø  HMW HA (1,500,000Da~3,000,000Da) can form a breathable film on the skin surface, make the skin smooth and moist, and block the invasion of foreign bacteria, dust, ultraviolet rays, and protect the skin from damage

Ø  MMW HA (1,000,000Da~1,500,000Da) can tighten the skin and keep moisturizing for a long time

Ø  LMW HA (400,000Da~1,000,000Da) can penetrate into the dermis, has a slight expansion of capillaries, increases blood circulation, improves intermediate metabolism, promotes skin nutrient absorption, has a strong wrinkle reduction function, can increase skin elasticity, delay skin aging
