Peptides in this category relate to skin structure, wound repair, and the signaling involved in connective tissue and cosmetic biology. Research often examines pathways affecting collagen production, tissue remodeling, and the response of skin and hair follicles to injury or aging. These compounds are discussed in educational contexts around skin appearance, dermal repair, and cosmetic research, with evidence ranging from laboratory and animal studies to a smaller body of human work, varying by compound and study model.
