Most sunscreens use oxybenzone — a confirmed endocrine disruptor detected in blood and breast milk after a single application, banned in Hawaii and Palau for reef damage. 3rd Rock uses 20% non-nano zinc oxide only — the single UV active with FDA GRASE designation. No chemical UV filters, no synthetic fragrance, no parabens.
✦ Ingredient Spotlight: Zinc Oxide Sunscreen
Zinc oxide physically scatters UV radiation without absorbing into the bloodstream — unlike chemical filters such as oxybenzone and avobenzone. It is safe for reef ecosystems, non-irritating to sensitive skin, and the only sunscreen active approved by the FDA for use on babies under 6 months. Non-nano zinc oxide does not penetrate the skin barrier.
Apply liberally to all exposed skin 15 minutes before sun exposure. Reapply every 2 hours, after swimming, or after sweating.
Certifications: Small-batch
