ARA-290 vs Decapeptide-12

Side-by-side comparison of key properties, dosing, and research.

Immune SupportRecovery & Repair
ARA-290
Skin & Cosmetic
Decapeptide-12
Summary
ARA-290 is a synthetic 11-amino acid peptide derived from the helix B region of erythropoietin (EPO). Unlike EPO, it selectively activates the innate repair receptor (IRR) without stimulating hematopoiesis, providing tissue protection, anti-inflammation, and neuropathy relief.
Decapeptide-12 is a synthetic 10-amino acid peptide developed for skin brightening and depigmentation. It selectively inhibits tyrosinase activity and downstream melanogenesis pathways, reducing hyperpigmentation, dark spots, and uneven skin tone without the irritation associated with hydroquinone.
