About this research area
Skin and hair peptide research is the largest category by entry count.
Skin and hair research is the largest single category in the library by entry count, because the cosmetic peptide field has produced a long catalog of distinct compounds. Apothify covers four broad families. Copper coordinating peptides (GHK-Cu, AHK-Cu) are studied for dermal matrix research. SNAP and Argireline style peptides (Argireline, SNAP-8) are studied around expression line research. Collagen and matrix signaling peptides (Matrixyl, Pal-KTTKS, Pal-GHK, Tripeptide-29, Hexapeptide-9, Hexapeptide-11) are studied for collagen related signaling. Pigmentation research peptides (Acetyl Tetrapeptide-30) are studied around melanocyte signaling.
What ties this category together is the experimental model. Skin and hair research happens largely in cultured human dermal cells (fibroblasts, keratinocytes, melanocytes) and reconstructed skin tissue models. Researchers measure how a peptide changes a cellular output: collagen synthesis, matrix metalloproteinase activity, melanin production, hair follicle dermal papilla activity. The same peptide can appear in studies with different cell types and produce different readouts. Comparing peptides on this dimension is exactly what the Compare tool is built for.
Cosmetic peptide research has its own vocabulary. Terms like INCI name, leave on percent, and formulation pH all matter. Researchers thinking about formulation studies will find that vocabulary on the Terminology page. Every entry in this category is sold for laboratory research use only. The Apothify library does not provide formulation advice and does not represent the products as cosmetic ingredients in finished consumer goods.
