([International Journal of Biological Macromolecules, 2024](https://pubmed.ncbi.nlm.nih.gov/38554903/))
- Polyglutamic acid and polylysine composite hydrogels promote wound repair and hemostasis through high water absorption, bioadhesion, calcium ion-mediated coagulation factor activation, and inherent antibacterial properties in a deep skin defect model.

- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
