SunSafe® Case Studies celebrate brands doing the right thing for people and the planet.
Our reports assess both product formulation and publicly available brand transparency at the time of review. Some products may contain stronger credentials than visible on an official webstore, so where information is limited we may mark criteria as pending clarification rather than failed.
We actively encourage brands to provide updated testing, sourcing, sustainability, and ingredient documentation so scores can improve over time. SunSafe® is designed to reward progress, not just perfection.
