Jamieson notes that peptides can be very helpful to manage some of the changes seen in skin as a result of hormonal shifts, such as dryness, sensitivity, and pigmentation. For women looking for a gentler alternative to retinoids (which can be too aggressive on hormonally sensitized skin), peptides in skincare offer a legitimate option
In a randomized, double-blind trial where women applied GHK-Cu encapsulated in a nano-lipid carrier twice daily for 8 weeks, the treatment group saw significant improvements in wrinkle depth and volume with no serious adverse events
Solvent evaporation, precipitation, and other solution-based methods create nanoparticles from dissolved drug molecules
