How much does it cost to develop a custom sunscreen spray formula?

Formulation development fees for a waterproof sunscreen spray typically run $5,000–$25,000 depending on the formulator's experience and project scope. On top of that, in-vivo SPF testing costs $3,000–$8,000 per claim per lab, and accelerated stability testing adds further cost. Budget $15,000–$50,000+ for a fully tested, FDA-compliant formula before manufacturing begins.
