Squalene

From Longevity Wiki

Squalene is a polyunsaturated triterpenoid compound with the formula C30H50 present as biochemical precursor in sterol biosynthesis, including cholesterol and steroid hormones in various organisms.[1] Squalene has multiple biological activities, which makes it a potential new functional food ingredient for nutrition enhancement or disease prevention.[2] Due to its six non-conjugated double bonds in structure, squalene enhances immune function, resists skin senility, and has hypolipidemic, antioxidant, antitumor, antibacterial, and detoxification effects. Squalene has been known for its various applications, such as an anti-cancer agent, an anti-oxidant agent, an anti-bacterial agent, a chemopreventive agent, an anti-aging agent, a detoxifier, and an adjuvant for drug carriers and vaccines.[3]

The skin naturally produces vitamin E, a lipophilic antioxidant present in normal human sebum, to prevent squalene oxidation. Vitamin E production is directly correlated to the amount of squalene. In individuals with acne, low levels of vitamin E contribute to increased levels of oxidized squalene.[4][5]
