Emerging evidence highlights the therapeutic promise of peptides, especially tripeptides, in accelerating tissue repair through diverse mechanisms
During the oxidation phase, accumulated ROS (such as hydrogen peroxide HO and superoxide anion O) in the cell can directly react with GSH in a non-enzymatic manner, or, under the catalysis of glutathione peroxidase (GPX), promote the oxidative coupling of two GSH molecules to form one molecule of GSSG, while releasing two protons (H) and two electrons (e)
What they can do is: Reduce pigmentation from sun damage, age spots, and melasma Even out skin tone and improve radiance Prevent future darkening when combined with sun protection Improve overall skin health and texture For deeper hyperpigmentation issues, dermatologists may recommend vitamin C in combination with other proven ingredients like hydroquinone, retinoids, or niacinamide
