Cosmetic & Dermal Research Peptides

Cosmetic peptides are short peptides studied in dermatological and cosmetic science research, for example in skin cell and extracellular matrix models. They are supplied here as lyophilized powder for laboratory research only.

What does this category cover?

Peptides studied in cosmetic science are usually grouped by proposed mechanism: signal, carrier, enzyme-inhibitor and neurotransmitter-inhibitor peptides (Pai et al., 2017). This category covers peptides from these research classes, supplied for in-vitro work such as skin cell and extracellular matrix models.

How is each lot tested?

Every lot is tested by an independent third-party laboratory against the same five-method panel before release: HPLC for purity, with a 98% minimum; mass spectrometry for identity; net peptide content against the label claim; endotoxin by LAL; and appearance. The full certificate for every lot is published in the Astramide certificate library, and each method is explained in how Astramide tests every lot.

How are these compounds stored?

Lyophilized compounds are held at -20°C, protected from light and moisture. Once reconstituted, they are held at 2 to 8°C and used within the window stated on the product page. Repeated freeze-thaw cycles should be avoided.

All compounds listed here are supplied for laboratory research use only. They are not intended for human or animal consumption, clinical use, or therapeutic application. Research use only. Not evaluated by the FDA.
