Abstract
Long exposure to ultraviolet A, UVA (315 nm - 400 nm) and ultraviolet B, UVB (280 nm - 315 nm) from the sunlight is harmful to human skin. It can cause unwanted pigmentation, skin aging, wrinkles and cancer. Thus, application of sunscreen lotion is necessary to protect us from these harmful ultraviolet. However, sunscreen lotion does not last for an entire day, its effectiveness degrades over time. In this study, we aim to investigate the effectiveness of various types of sunscreen lotion. The ingredient of the chosen sunscreen includes common ingredient such as ethylhexyl methoxycinnamate and titanium dioxide. In this experiment, ethylhexyl methoxycinnamate show degradation after exposed to tungsten-halogen lamp for 180 minutes. However, mixing titanium dioxide into ethylhexyl methoxycinnamate did improve its stability and protection against UVA and UVB.
