[Synopsis] The chemical compositions of low-molecular weight (low-MW) hyaluronic acid (HA) from comb and the effect of keepingb moisture contents on skin by a clinical test were investigated. The low-MW-HA prepared from comb contained the following components: moisture 2.2 ~ 2.6%, nitrogen 3.84%, total protein 3.04%, free amino acid 4.08%, N-acetyl-D-glucosamine 0%, HA 13.4% and dextrin( food additives) 75.0%. The main components of the low-MW-HA were two components, MW 1,500( 47%) and MW. 5,000( 33%). We studied the effect of low-MW-HA( Will-HA) on the effect of keeping moisture contents of skin by a clinical test. The clinical test was done in a national hospital in the Peoples Republic of China in 2006. As a result, it was shown that the low-MW-HA have the effect of keeping moisture in the skin.
