Summary
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.
Cerebrolysin is a porcine brain-derived neuropeptide complex that mimics the action of endogenous neurotrophic factors (BDNF, NGF, GDNF, NT-3). It promotes neurogenesis, neuroprotection, and synaptic plasticity, and is approved in many countries for stroke, traumatic brain injury, and Alzheimer's disease.
