As people age, nutrition and the sunshine, the environment, the influence of such factors as the synthesis of hyaluronic acid (PRP) HA gradually decline, the ability of the skin in the content of hyaluronic acid (PRP) HA will reduce gradually, people in the embryonic period of hyaluronic acid (PRP) HA content is the highest, gradually reduced after birth.
If the relative levels of hyaluronic acid (PRPd) HA in people aged 20 were set at 100 percent, the levels of hyaluronic acid (PRP) in people aged 30, 50 and 60 dropped to 65 percent, 45 percent and 25 percent, respectively.
When the skin of hyaluronic acid (PRP) HA content is lower than a usual monohydrate, will gradually reduce the water content of the skin, caused by aging cuticle, skin becomes rough, wrinkles, loss of elasticity, appear aging, this phenomenon is commonly after 25 years old.
This is also one of the main reasons for the skin difference between middle-aged and old people and children.
And hyaluronic acid (PRP) in human skin HA damage associated with ultraviolet ray, so for a long time engaged in outdoor work, outdoor, plateau life operations personnel from indoor staff look rough skin.
Human double-blind clinical trials have shown that after 4 hours of oral administration, the content of hyaluronic acid in the blood begins to increase significantly, reaching its peak at 12 hours, 70 times higher than the control group.
A stable concentration can be achieved after 7 days of continuous administration.
