A Study on the Value of Brewer's Yeast, Aloe vera L., and Silk Peptide Extracts as Natural Cosmetic Materials

This is a ‘Study on the Value of Brewer's Yeast, Aloe vera L., and Silk Peptide Extracts as Natural Cosmetic Materials’. In order to clarify the value of single and mixed extracts of brewer's yeast, Aloe vera L., and silk peptide as natural cosmetic materials, the researchers measured the physiological activity efficacy related to beauty (antioxidant content - total polyphenol content and total flavonoid content, antioxidant activity efficacy - DPPH radical scavenging activity and ABTS radical scavenging activity, and enzyme activity - tyrosinase inhibitory activity and elastase inhibitory activity) and manufactured a spray-type mist cosmetic by adding a mixed extract of brewer's yeast, Aloe vera L., and silk peptide extracts in a 1:1:1 ratio, and then conducted a quality evaluation. As a result, it was found that brewer's yeast, Aloe vera L., and silk peptide extracts have excellent physiological activity efficacy related to beauty for promoting skin health, preventing aging, improving wrinkles, and whitening. The quality evaluation results for cosmetics were also found to be high overall, indicating that brewer's yeast, Aloe vera L., and silk peptide extracts have value as natural cosmetic materials.
