4. Application:
The body in embryonic period has the highest HA content, but it gradually reduced after birth. HA content varies with each individual even among the crowd of the same age. Reduction of HA content will directly lead to skin ageing and functional decaying. For example, HA content significantly reduced in the progeria patients.
There is still many limitations for the external use of HA on skin , which can only work as lubrication and water retention.. However, the oral use of HA can increase endogenetic HA level through digestion and absorption, which makes skin moist, glossy and elastic.
HA also plays an important role of water retention and lubrication in other tissues and organs, such as joint cavity, blood vessel, heart and brain. Decrease of HA level of these tissues can result in arthritis, arteriosclerosis, pulse disorder and brain atrophy. Oral HA can restore the normal content of HA in body and delay apolexis and make the body energetic.
