Tocotrienol reduces water loss from the skin and strengthens the skin’s barrier function. Either singly or in combination with other ingredients, tocotrienol improves efficacy in skin hydration .
Unlike normal skin ageing, photo-ageing results from constant and prolonged exposure to the sun’s harmful UV rays. UV radiation increases the production of free radicals and reactive oxygen species in different layers of the skin causing cellular damage which hastens the ageing process and increases the risk for skin cancer. Excellent antioxidation properties of up to 60 times greater than tocopherol confer tocotrienol the ability to help protect the skin from ageing and UV-induced damage caused by constant and prolonged sun exposure . Formulations with tocotrienol exhibited a radical skin factor of 4.15. The RSF measures a substance’s ability to reduce free radicals generated in the skin during UV exposure. An RSF of 4.15 suggests that tocotrienol formulations reduce free radical production in the skin by 76% resulting from exposure to the sun’s harmful UVA and UVB rays .
Human beings are exposed to radiation every day. Radiation can cause cells to grow abnormally- a process that could lead to cancer. Normally, at low doses, cells are able to repair any radiation-related damage easily. However, in excessively high doses, affected cells may die causing tissues and organs to fail.
Tocotrienols are found to improve survival and reduce radiation-induced injuries in tissues and organs after total body irradiation in animal models . In addition to its excellent antioxidant properties, tocotrienols’ potent radioprotective effects arise from its ability to reduce highly reactive oxidants in the blood by inhibiting a protein called HMG-CoA reductase .
