Science
Mechanism of Action
This ingredient, specifically its chalaza-derived glycopeptides (CHAH), precisely targets melanin production by inhibiting tyrosinase activity. This action is supported by the significant downregulation of key genes involved in melanogenesis, including MITF, TYR, TYRP1, and TYRP2. Furthermore, it supplies beneficial peptides, amino acids, carotenoids, and antioxidants, which may protect the skin from aging and improve its overall texture.

Formulation
Stability
The hydrolysis process is known to enhance the solubility of egg yolk and chalaza proteins across a wide range of pH conditions. While the optimal pH for enzymatic hydrolysis of egg yolk protein is around pH 9, ideal pH conditions for stabilizing emulsions with chalaza particles are around 3 and 3.5, where surface electrical charges are optimized.
