Applications in Cosmetics
- Moisturizing: It can absorb a large amount of water in the air and form a smooth protective film on the skin surface, effectively preventing water loss. Its moisturizing effect is 2 - 3 times better than that of hyaluronic acid.
- Whitening: It can inhibit the activity of tyrosinase, thus reducing the production of melanin and achieving a whitening effect.
- Anti-aging: It promotes the activity of fibroblasts and is helpful in reducing wrinkles and delaying skin aging.
- Enhanced Absorption: With good slow-release properties, it can promote the skin's absorption of other skin care ingredients.
1. What is polyglutamic acid and how is it related to cosmetics?
Polyglutamic acid is a biopolymer composed of glutamic acid units. In the cosmetics industry, it is a highly sought - after ingredient. It has excellent water - retaining properties, which can effectively hydrate the skin, making it softer, smoother, and more elastic. This helps to improve the overall appearance and texture of the skin.

2. What are the main benefits of using polyglutamic acid in cosmetics?
- Moisturization: It can absorb and hold a large amount of water, providing long - lasting hydration to the skin. This helps to prevent dryness and keep the skin in a healthy state.
- Skin protection: It forms a thin, protective film on the skin's surface, which can shield the skin from environmental damage such as pollution and UV rays.
- Enhanced skin barrier function: By maintaining skin moisture, it can strengthen the skin's natural barrier, reducing the risk of skin problems like sensitivity and inflammation.
3. Is polyglutamic acid suitable for all skin types?
Generally, polyglutamic acid is suitable for all skin types, including sensitive skin. It is a gentle and natural ingredient that is well - tolerated by most people. However, as with any cosmetic ingredient, individuals with extremely sensitive skin may want to perform a patch test before using a new product containing polyglutamic acid.

4. How does polyglutamic acid compare to other moisturizing ingredients in cosmetics?
Compared to some traditional moisturizing ingredients like glycerin and hyaluronic acid, polyglutamic acid has a stronger water - binding capacity. It can hold more water per unit weight, which means it can provide more effective and long - lasting hydration. Additionally, it has better film - forming properties, which can offer additional protection to the skin.
