Initial formula development typically takes 4-8 weeks, including ingredient sourcing, stability testing, and texture refinement. Stability testing (heat, light, time) adds 4-12 weeks depending on claims. If you need clinical data or preservative efficacy testing, add 8-16 weeks. Fast-track timelines exist for simpler formulas. Working with vetted chemists on the AJ Cosmo Labs platform accelerates timelines significantly.
