Abstract:
Collagen is an important compound in human skin to make people look younger. Collagen is used in facial serum production can be extracted from various natural sources, which contributed to different results on human skin. The objective of this study was to compare efficacy of collagen that derived from aquatic sources; tilapia, jellyfish and starfish, on human skin moisture and skin elasticity before and after used the facial serum. First, collagen which derived from tilapia, jellyfish and starfish was formulated and was used to determine its physical property, pH and viscocity. Second, protein content in collagen was measured by Bradfords method. The results showed that collagen which derived from jellyfish had more protein than that derived from tilapia and starfish, respectively. Finally, the skin moisture content was measured by Moistsense® and the skin elasticity was measured by Cutometer®. The skin moisture and skin elasticity of each collagen facial serum were evaluated on volunteers and the results were compared. After 10 weeks of treatment, the study of skin moisture content in the facial serum with collagen derived from tilapia and jellyfish gave an increasing of the skin moisture content significantly whereas the facial serum with collagen derived from starfish did not give an increasing of the skin moisture content significantly. In addition, the study of the skin elasticity in the facial serum with collagen derived from tilapia and jellyfish showed significant induce skin elasticity while the facial serum with collagen derived from starfish did not. This result was consistent with the amount of proteins in tilapia, jelly fish and starfish. Hence, the information generated from this study may be useful for appropriately selection of collagen sources and useful for collagen facial serum production development widely.
