Collective findings from these studies underscore persistent translational challenges, including size heterogeneity, rapid renal clearance, and limited long-term toxicological data, highlighting the need for improved targeting, surface modification, and synthesis control to support clinical translation [91, 190]

Peptides can be used through topical serums, hair products, supplements, or advanced treatments, often working best as part of a broader hair health strategy that improves scalp environment and follicle function

Extrapolating this to genital tissue application is speculative, but the same fibroblast populations are present in vulvovaginal and penile dermis

Interestingly, some DAMs, such as L-tryptophan and sphingosine 1-phosphate, showed an evident negative correlation with changes in the level of TNF- and IL-17, while tightly positively correlating with altered concentrations of anti-inflammatory cytokines and chemokines, such as MIP-1 and RANTES
