Synthetic actin-binding fragment of thymosin β4

The migration-and-angiogenesis peptide behind the recovery hype.

A short synthetic peptide (Ac-LKKTETQ) taken from the actin-binding motif of thymosin β4. Most of the cited healing research actually used the full 43-amino-acid thymosin β4 protein — not this fragment — a distinction the recovery marketing tends to blur.

Copper-binding tripeptide

The copper peptide that actually earned its place in skincare.

A naturally occurring tripeptide (Gly-His-Lys) that chelates copper and upregulates collagen, elastin, and repair signaling. It has the strongest human (topical) evidence of the 'cosmeceutical peptide' group — though those trials are small and short — plus a deep preclinical tissue-remodeling literature.

Synthetic pentadecapeptide (gastric-derived)

The repair peptide the research world can't stop talking about.

A synthetic 15-amino-acid peptide described as a partial sequence of a protein from gastric juice, studied widely in animal models for tendon, muscle, and gut-lining repair. The preclinical signal is broad but comes largely from one research group — controlled human data is the missing piece.

Anti-inflammatory tripeptide

The three-residue tail of α-MSH that calms inflammation.

A tripeptide from the tail end of alpha-MSH, studied for anti-inflammatory activity in the gut and skin. Its mechanism appears to run largely independent of melanocortin receptors; the preclinical data are real, but human trials are absent.
