In fact, by reducing oxidative stress, glutathione may help the skin recover more efficiently from the increased turnover caused by retinol
GHK-Cu enhances wound healing through multiple mechanisms including stimulation of angiogenesis (essential for delivering nutrients and oxygen to healing tissue), enhancement of collagen and glycosaminoglycan synthesis (providing structural matrix for tissue reconstruction), and modulation of inflammatory responses (preventing chronic inflammation while supporting protective immune functions)
