# Sunscreen law updates

When each sunscreen law we track took effect, every change to one since we started recording changes, and when we last re-read each law’s sources. Changes are only logged against a primary source, such as the statute, ordinance or official notice.

Laws last checked October 14, 2026. [How we verify laws](https://reeflabel.com/guide/methodology/#laws)
