Diverse Functions of Polyglutamic Acid (PGA) in Skincare
Polyglutamic Acid (PGA) offers various molecular weights, each serving distinct roles in skincare. With a molecular weight around 5k Da, PGA ensures easy skin penetration and absorption, while PGA-Oligo effectively combats free radicals, repairs photoaging, and rejuvenates the skin. On the other hand, higher molecular weights (ranging from 700k to 1000k Da) enhance water retention, ensuring optimal skin moisturization. These varied molecular weights cater to specific skincare needs, providing multifaceted benefits.
