Glycine Soja Oil



Glycine Soja Oil description

_Glycine soja_ (soybean) oil is a non-fragrant plant oil with multiple uses for skin. As with all plant oils, it has skin-smoothing emollient properties, plus it’s a good source of antioxidants and replenishing fatty acids. [br] [br] Studies have shown that compounds in soy, most likely isoflavones, help fade stubborn discolourations from sun exposure and other sources. They help to reduce excess transfer of melanin to skin’s surface, thereby visibly reducing hyperpigmentation. [br] [br] Soybean oil’s antioxidant content includes polyphenols known as isoflavones, particularly daidzein and genistein. These have been shown to help protect skin from UV light-triggered damage. The antioxidants in soy can also help maintain hydration by preventing water loss. [br] [br] In oil form, soy can help maintain skin’s smooth, supple surface thanks to its blend of fatty acids such as palmitic, stearic, oleic, and linoleic. These fatty acids in the oil plus the naturally-present antioxidants are responsible for the soothing effect soy has in the presence of external aggressors.
