Cosmetology-related Physiological Activities of Aloe Vera L., Brewer’s Yeast and Silk Peptide

This study attempted to investigate the values of Aloe vera L., Brewer’s yeast and Silk peptide as a natural ingredient of cosmetics. For this, samples were collected by solvent (distilled water, ethanol) and their cosmetology-related physiological activities were assessed. To analyze the synergy effects of three different ingredients, furthermore, the three materials sampled by solvent were mixed in a 1:1:1 ratio and cosmetology-related physiological activities were analyzed. In Aloe vera L. extracted with distilled water, total polyphenol contents, total flavonoid contents and DPPH radical scavenging activity were 180.96 mg TAE/g, 1846.79 mg QE/g and 61.43% respectively. In other words, it revealed better effects compared to the samples extracted with ethanol. The tyrosinase inhibitory effects (40.92%) were the highest in Aloe vera L. extracted with ethanol while elastase inhibitory effects (25.57%) were the greatest in Brewer’s yeast extracted with distilled water. The mixture (1:1:1) of the samples extracted with distilled water was greater than the mixture of the samples (1:1:1) extracted with ethanol in terms of total polyphenol contents, total flavonoid contents, ABTS radical scavenging effects and elastase inhibitory effects. In terms of DPPH radical scavenging effects and tyrosinase inhibitory effects, on the contrary, the mixture of the samples (1:1:1) extracted with ethanol was higher than the mixture (1:1:1) of the samples extracted with distilled water. The above analysis confirmed that it was Aloe vera L. extracted with distilled water which revealed the most active antioxidant activity among Aloe vera L., Brewer’s yeast and Silk peptide extracts. Among the mixtures, the samples extracted with distilled water revealed better effects than those extracted with ethanol. In yeast activities, tyrosinase inhibitory effects and elastase inhibitory effects were higher than those of single materials. It was concluded that the mixture samples (1:1:1) with distilled water are valuable enough for anticorrugation and mixture samples with ethanol for whitening as the natural ingredients of cosmetics.
