Peptides relating to skin, hair or pigmentation.
Peptide structures described in topical or local contexts. Comparatively many in-vitro data, individual human trials on specific endpoints — transferability to everyday cosmetics is not automatic.
This overview is editorial. It describes the evidence base, not a usage recommendation.

KTTKS is a fragment of the procollagen I sequence and appears to be part of a feedback mechanism in fibroblasts: elevated concentrations signal intact collagen …
SNAP-8
Human trial3 studies · 3 observations
SNAP-8 is an octapeptide variant of Argireline. The sequence corresponds to the N-terminus of the SNAP-25 protein. As with Argireline, the postulated mechanism …
