Abstract

In this study, we examined the effects of various molecular weights (1, 10, 50, 100, 660, and 1500 kDa) of sodium hyaluronate (HA), which were prepared by enzyme hydrolysis, on the collagen synthesis, anti-inflammation and skin absorption. These HA did not significantly affect the viability of human dermal fibroblast Hs68 cells. Among them, 1500 kDa, 50 kDa HA most significantly increased collagen production by 59%, and 50% in the Hs 68 cells, respectively. Whereas 1500 and 660 kDa HA hardly pass through mouse transdermis membrane, lower molecular weights (1, 10, or 50 kDa) of HA showed time-dependent increase in skin permeation. HA of 50 kDa showed highest anti-inflammatory effects by reducing nitric oxide and tumor necrosis factor-α production in the RAW 264.7 cells, comparing to other HA (1, 10, and 100 kDa HA). Recently, there is no report about anti-wrinkle and anti-inflammatory effects and skin permeation of different molecular weights HA (1, 10 , 50, 100, 660 and 1500 kDa), which were produced by enzyme hydrolysis. These results suggested that 50 kDa HA can be potent candidates for the development of effective anti-aging and anti-wrinkle cosmetic agents. The results of this study demonstrated that among those HA with different molecular weights, 50 kDa HA showed highest anti-inflammatory activity, significant capability to induce collagen synthesis and high level of skin permeation.
