Polyglutamic acid

Определение

ChEBI: A macromolecule composed of repeating gamma-linked L-glutamyl units.

преимущество

The primary benefit of polyglutamic acid is its impressive ability to hydrate skin. Because it’s a polymer, it forms a flexible, smooth, moisture-binding film on skin’s surface. This film helps skin keep moisture in its surface layers, even in conditions of low humidity, making polyglutamic acid an effective humectant. In addition to its abilities to aid skin in moisture retention, polyglutamic acid soothes and helps increase the production of natural moisturizing factors (NMF) in skin, which contributes to having a healthier barrier and balanced hydration. Polyglutamic acid hydrates skin but also performs other roles as well including wrinkle reduction, balancing the effects of chronic sun exposure and enhancing wound healing.

Побочные эффекты

Polyglutamic acid is generally considered safe and allergic reaction side effects are rare, which may result in itching, swelling, redness, burning sensation or blisters. Before applying Polyglutamic acid to your face, you can perform a patch test to ensure that you are tolerating this ingredient well.
