Yes. Stability testing confirms that your formula remains safe, effective, and aesthetically consistent across its intended shelf life, typically 12–36 months. Accelerated stability testing at 45°C and 75% relative humidity over 8–12 weeks is the industry standard minimum. Retailers, co-packers, and EU/UK regulators all require documented stability data. A cosmetic formulator you find through AJ Cosmo Labs can coordinate this testing or refer you to a qualified third-party lab.
