What is Polyglutamic Acid?
Polyglutamic Acid (PGA) is a powerful humectant derived from fermented soybeans. It is known for its exceptional ability to retain moisture, making it a star ingredient in modern skincare. Unlike Hyaluronic Acid, which holds up to 1,000 times its weight in water, PGA can hold up to 5,000 times its weight, providing intense hydration.

Precautions When Using Polyglutamic Acid Serum
While Polyglutamic Acid is generally safe for all skin types, it is important to consider the following precautions:
- Patch Test First: Always conduct a patch test before applying a new serum to ensure you do not experience any irritation or allergic reactions.
- Avoid Overuse: Using too much product can lead to an overly sticky or greasy feeling on the skin. A small amount is sufficient for effective hydration.
- Layering with Other Ingredients: Polyglutamic Acid pairs well with Hyaluronic Acid and Vitamin C but should be used cautiously with strong exfoliants like AHAs and BHAs to prevent potential irritation.
- Use on Damp Skin: For maximum absorption and hydration benefits, apply the serum to slightly damp skin rather than dry skin.
- Sun Protection: Although PGA itself is not photosensitizing, always follow up with sunscreen during the day to protect your skin.
