Skin, Hair & Cosmetic

Skin, hair and cosmetic research explores the molecular mechanisms responsible for collagen production, extracellular-matrix integrity, pigmentation, follicular biology, wound repair, hydration and visible changes associated with ageing.

Skin is a complex organ containing multiple cell types, structural proteins and signalling networks. Researchers investigate fibroblast activity, collagen and elastin synthesis, angiogenesis, oxidative stress and inflammatory processes that influence skin structure and appearance.

Copper-binding peptides such as GHK-Cu have attracted particular scientific interest because copper is involved in several enzymes associated with connective-tissue biology and cellular repair. Other research areas include melanocortin signalling and pigmentation, hair-follicle cycling, growth-factor signalling and mechanisms associated with dermal regeneration.

Hair research similarly examines the transition between anagen, catagen and telogen phases of the follicular growth cycle. Scientists study how hormones, growth factors, inflammatory pathways and local cellular signalling influence follicle behaviour.

The Peptide Research Skin, Hair & Cosmetic category groups together compounds associated with these areas of experimental investigation. Some compounds may also be relevant to injury-healing or anti-ageing research because connective-tissue biology and cellular regeneration overlap substantially.

This category is intended as a research navigation tool rather than a statement that any individual compound has been demonstrated to produce a cosmetic outcome.
