Yeast Extract Benefits:
Antioxidant
Moisturizing
Soothing

Derived from yeast (e.g Saccharomyces cerevisiae), yeast extract is a mixture of flavonoids, sugars, vitamins, and amino acids. This unique derivative of fungi also contains a high concentration of antioxidants, which are capable of neutralizing harmful free-radicals that are present in the environment. This protective mechanism not only helps to maintain the skin’s overall quality and appearance, but also allows additional skin care advantages such as increased moisturizing and soothing properties. 1

By helping to reduce the amount of oxidative stress that occurs on the skin, the benefits of yeast extract can induce a calming effect that can help soothe and alleviate problematic skin. Furthermore, yeast extract has shown abilities in serving as a possible biosurfactant for moisturizing formulas. This allows it to boost moisturize-retention and improve overall hydration, making yeast extract a good candidate to infusing into lotions and creams. 2 Overall, topical application of yeast extract can better equip the skin with natural protective qualities that promote beautiful skin.
