Expect 8–16 weeks for custom formulation development and revision cycles, plus 4–12 additional weeks for stability and challenge testing required for a safety dossier. Founders who start with a validated azelaic acid base formula — available from several chemists on the AJ Cosmo Labs platform — can reduce the formulation phase to 4–6 weeks, getting to production faster while maintaining quality.
