TLDR Polyglutamic acid is a valuable, sustainable ingredient for skincare and haircare products.
Polyglutamic acid (PGA) is a versatile biopolymer with significant potential in the cosmetic industry due to its biocompatibility, water solubility, and film-forming properties. It is used in skincare and haircare products for its moisturizing, anti-aging, depigmentation, and sun protection benefits. PGA enhances skin hydration, elasticity, and collagen production, reduces hyperpigmentation, and forms protective barriers. In haircare, it shows promise in treating alopecia by inhibiting the 5-alpha reductase enzyme and promoting hair growth. PGA's biocompatibility and biodegradability also make it suitable for wound healing applications. Future research should focus on optimizing production processes and exploring new microbial strains to enhance PGA yields, ensuring the development of effective and eco-conscious cosmetic products.
