What Are the Benefits of Polyglutamic Acid?

April 24, 2025

The older we get, the more important our skin health becomes. Polyglutamic acid, notable for its hydrating capabilities, is among the many ingredients formulated to tackle visible signs of aging and maintain supple, fresh, and healthy-looking skin.

You can incorporate this powerful ingredient into your skincare routine with the Hydrating Gel Mask from Isomers Skincare! Keep reading to learn about the benefits of polyglutamic acid and how you can use it.

What Is Polyglutamic Acid?

Polyglutamic acid is a non-exfoliating humectant known for its powerful moisturizing and hydrating capabilities—it can hold 5,000 times its weight in water!

Along with adding more moisture to the skin, it also helps restore skin elasticity, increase NMF production, and reduce the appearance of wrinkles and fine lines. 

If you’re aiming to tighten your skin and restore its smooth, supple feeling, PGA is a great ingredient to include in your regular skincare routine! It can be paired with other actives like hyaluronic acid and peptides and boosts the absorption of the other ingredients in serums and creams. 

The Skincare Benefits of Polyglutamic Acid 

Our skin changes in many ways as we age, and each concern requires different ingredients to be tackled effectively. Polyglutamic Acid addresses several aging effects and provides the following benefits:

  • Improves skin elasticity: This humectant stimulates the elastin and collagen production in your skin to help maintain its firmness and bounce.
  • Offers moisturizing capabilities: Retains the moisture on the skin’s surface to maintain a fresh, dewy appearance and improve skin texture. This is beneficial for those who deal with a dry skin type.
  • Strengthens the skin barrier: Helps the skin maintain resilience against dehydration and other environmental stressors.
  • Reduces fine lines & wrinkles: The added hydration from PGA helps the skin gain a plumper look and texture, reducing the appearance of lines and wrinkles.
  • Works for many skin types: Polyglutamic acid is accessible for people with varied skin types, including dry, normal, and combination.
