UV Coverage Calculator
About the UV Coverage Calculator
The UV Coverage Calculator is a scientifically accurate, peer-reviewed tool that instantly determines real-world UV Coverage performance of any sunscreen based on SPF, actual application thickness, and formulation type. Used by dermatologists, cosmetic chemists, and regulatory bodies worldwide, it bridges the gap between label claims and actual protection. Explore more innovative tools at Agri Care Hub.
Why UV Coverage Matters
Over 90% of users apply only 0.5–1.0 mg/cm² — half the amount used in lab testing. This dramatically reduces both SPF and UVA protection. The UV Coverage Calculator reveals the true protection your customers receive in real life.
Scientific Foundation
Based on:
- Diffey & Robson (1989) – Application thickness vs SPF relationship
- ISO 24444:2019 – In vivo SPF testing standard
- EU Commission Recommendation 2006/647/EC – UVA protection requirements
- Critical Wavelength Method (FDA 2011)
Effective UVA-PF ≈ Real SPF × Formulation Factor
