A small lab in Santa Monica.
We compound peptide serums one bottle at a time. Twelve clinical actives, three vehicles, a rules engine that picks across them by your skin’s actual job list — and a ninety-day cycle that reformulates around your results.
What we’re not: a category disruptor. We did not invent peptide skincare. We did invent the workflow that lets a single brand compound for the variance of real human skin without giving up on potency, pH, or safety. Most of the science here is sixty years old. The system around it is new.

Cosmetic chemist, formerly of L'Oréal R&I and Estée Lauder Companies' Skin Biology Group. She left to start Sequence12 in 2024 after deciding that the bottleneck in personal skincare was variance — every skin is different, and no off-the-shelf formula meets all of them. Sequence12 is her answer.
She holds a PhD from Sorbonne in cosmetic peptide stability. She lives by the beach in Santa Monica and takes her morning drip coffee too seriously.
