- This research studied the effect of snake skin and fish scale on blocking the UV light, and it also checked the possibility of developing the natural sun block safe to human body. UV blocking effect of snake skin and fish scale was checked through UV transmission, absorbance measurement, and observation through electron microscope. As a result of these three experiments, snake skin is effective on blocking UV, especially UVB. Surface observed through electron microscope was smooth but had many concave holes; therefore, total reflection occurred on the flat surface, while the light penetrated or scattered inside. Furthermore, as the surface is curved when it covers the snake body, it becomes better structure to reflect the light. Secondly, in order to develop organic sun block, serpent skin extract was used instead of water, and the clinical test for this sun block was performed twice on 6 and 16 people each, thus the safety of serpent skin as a ingredient of sun block was checked. 4 types of herb essential oil were used in order to add as an antiseptic, and Lemon grass had most outstanding effect among those types. As a conclusion, UV blocking effect and harmless to human body of snake skin was proved which shows that it is an adequate ingredient of organic sun screen.
