Acetyl Tetrapeptide-11

Basic Description

​​​​​​​​​ ​Structure and function​ ​:
Acetyl tetrapeptide-11 is a synthetic tetrapeptide with the sequence ​Ac-Gly-Pro-Arg-Pro-NH₂​ ​, works through the following mechanisms:
1. ​​Resistance to blue light damage​ ​：Inhibit blue light-induced reactive oxygen species (ROS) generation and protect keratinocytes from photoaging damage.
2. ​​Antioxidant repair​ : Activate ​Nrf2/ARE signaling pathway​ ​, enhance the expression of cellular antioxidant enzymes (such as superoxide dismutase and glutathione).
3. ​​Barrier strengthening​ ​：Promote the synthesis of filaggrin and reduce transepidermal water loss (TEWL).

​ ​Application Areas​ ​:
• ​​Cosmetics ​: Anti-blue light essence, sunscreen, and mask for repairing late-night sleep.
• ​In vitro studies ​：Study on blue light-induced skin oxidation model and Nrf2 pathway regulation mechanism.
