Simmondsia Chinensis (Jojoba) Seed Oil description

_Simmondsia chinensis_ (jojoba) seed oil is a non-fragrant emollient extracted from the seeds of a perennial shrub. It has been shown to enhance skin’s restorative properties and can also provide topical skin-soothing benefits. _Simmondsia chinensis_ (jojoba) seed oil is a rich source of numerous fatty acids and antioxidants. Even though labeled as an oil, it is actually a liquid-wax ester with a texture similar to that of human sebum, the oil-like substance secreted through skin’s pores. This makes it an excellent moisturizer for dry or dehydrated skin. Interestingly, though the molecular size of jojoba seed oil can penetrate the pore lining where natural sebum already exists, it does not appear to cause an issue with oily or acne-prone skin, likely because it doesn’t solidify in the pores. Instead, studies demonstrate the reverse to be true, with jojoba seed oil helping regulate sebum production and even dissolving built-up sebum deposits. Its anti-inflammatory properties also help curb acne-triggering irritation. _Simmondsia chinensis_ (jojoba) seed oil has the distinction of feeling lighter and less greasy than many other oils, particularly highly saturated oils such as coconut. It is one of the more stable plant oils in use today. Unlike many other plant-derived oils, jojoba seed oil is considered inedible due to a component known as simmondsin which interferes with the absorption of nutrients from food. Note that this effect occurs via an interaction with digestive chemicals in the intestines, not via topical absorption since it is metabolized within skin. Simmondsin is largely responsible for the soothing properties jojoba oil has on skin.
