About
Geltor was founded by Princeton molecular biology Ph.D. students Nick Ouzounov and Alex Lorestani to replace animal-derived proteins and harsh chemical processes with biodesigned alternatives. The company creates sustainable, ethically sourced protein ingredients for beauty, nutrition, and wellness customers, treating biodesign as a faster way to deliver effective specialty proteins. Its PrimaColl collagen polypeptide has received FDA GRAS clearance for food use and is used in topical beauty products, including a vegan signaling collagen supplement launched with TOSLA. Geltor positions itself as the nexus of biology, beauty, and design for industry partners.
