Anti-aging and antioxidant peptides are being investigated with a medical approach that combines molecular biology, pharmacology, and clinical trials. The studies assess mechanisms such as stimulation of collagen and elastin synthesis, modulation of signaling pathways for tissue repair, inhibition of matrix metalloproteinases, and neutralization of oxidative stress. Clinical markers include changes in wrinkle depth, elasticity, hydration, and biomarkers of inflammation; safety and pharmacokinetics are monitored in controlled trials.
Attention: Additional randomized long-term studies are needed to definitively confirm the long-term benefits.
Observed beneficial effects in humans: improved skin elasticity and firmness; visible reduction of fine lines and wrinkles; increased hydration and a more even tone; accelerated healing of minor wounds and reduced local inflammation; better protection against oxidative stress in skin cells.
