Skin & cosmetic research

The dermatological and cosmetic research area — copper, melanocortin and signal peptides studied in skin remodelling, pigmentation and appearance.

Cosmetic-peptide research studies compounds acting on skin and pigmentation biology: GHK-Cu (a copper-binding tripeptide studied for collagen synthesis and skin remodelling), the melanocortin peptides Melanotan-1 and Melanotan-2 (studied for melanogenesis), and signal peptides such as SNAP-8 (studied for expression-line research).

This hub groups the research compounds New-U supplies in this area alongside the on-site guides that summarise the published science. Every compound is lab-verified at >99% HPLC purity with a Certificate of Analysis per lot. Supplied strictly for laboratory and research use only — not for human or veterinary consumption.

Frequently asked questions

What is GHK-Cu studied for?

GHK-Cu is a naturally occurring copper-binding tripeptide studied in dermatological research for its role in collagen and extracellular-matrix synthesis, wound-healing signalling and skin remodelling. New-U supplies it for laboratory research use only.

What are the melanocortin peptides in this area?

Melanotan-1 and Melanotan-2 are synthetic analogues of alpha-melanocyte-stimulating hormone studied for their effect on melanogenesis (pigment production) in research models.

How is purity verified?

Every lot is independently tested by Janoshik Analytics and/or Freedom Diagnostics, with RP-HPLC purity and ESI-MS identity verification at >99%, and a Certificate of Analysis published per lot.
