Yeast Essence E100

Introduction

Yeast Essence E100, derived fromSaccharomyces cerevisiae, is full of amino acids, nucleic acids, peptides, minerals and vitamins that work together to allow the skin’s natural surface rejuvenation process to function at its best. On dry basis, E100 contains at least 30% amino acids, 15% nucleic acids and 30% peptides, all of which are the main ingredients of the NMF (natural moisturing factors). Amino acids and peptides can be easily absorbed by skin to promote collagen synthesis and nourish the skin cells. Nucleic acids are essential for skin cells metabolism, can deeply revitalize and soften skin.

Mechanism

Mechanism of functions

Property

Small molecular weight (Mw) of Yeast Essence E100

The Mw of E100 was determined using volume exclusion chromatography. The results showed that the main components of E100 were amino acids, nucleic acids and peptides. The Mw of E100 was small (mostly under 1000D) so that it can be easily absorbed by skin cells.

 

Efficacy

1. Anti-aging -- Free radicals scavenging

Scavenging rate of hydroxyl radicals

 

Scavenging rate of DPPH radicals

 

Scavenging rate of superoxide anion

 

Free radicals, which are harmful compounds generated during the oxidation reaction in human body, can damage the skin tissues and cells, which cause aging effects. The results of the efficacy tests showed that E100 were effective in the scavenging of hydroxyl radicals, DPPH radicals and superoxide anion.

 

2. Whitening -- Inhibition of tyrosinase

Inhibition rate of theformation of melanin

 

Mechanism of the inhibition of tyrosinase

 

Inhibition ability of E100 on tyrosinase was strong. E100 acted as an inhibitor, and the peptides it contained can react and compete with tyrosinase, blocking the tyrosinase-catalyzed reaction of dopa to dopaquinone, thus blocking the intracellular formation of melanin.
