How long does barrier cream formulation take from concept to stable prototype?

Expect 8 to 16 weeks for a fully stable barrier cream prototype. This covers initial formulation (2–4 weeks), accelerated stability screening (4–6 weeks), and at least one revision round. If you need real-time stability data for retail buyers or EU submission, add another 12 weeks minimum. Posting your brief early on the AJ Cosmo Labs app helps you find available formulators and avoid delays.
