How do I know if a cosmetic chemist is qualified to formulate for sensitive or eczema-prone skin?

Ask for a portfolio of previous sensitive-skin or clinical skincare formulas, references from launched brands, and confirmation that they understand EU fragrance allergen restrictions and FDA OTC monograph rules. AJ Cosmo Labs requires formulators to complete a verification process before joining the platform, so you are starting with pre-screened professionals rather than unknown cold contacts, saving significant due-diligence time.
