Sunscreen Safety: Chemical vs Mineral Filters

Sunscreen is essential for protecting against skin cancer, but not all formulas are equal. Some chemical UV filters are linked to hormone disruption and coral reef damage.

Chemical vs Mineral Sunscreens

Chemical Filters (Avoid)

• Oxybenzone — Hormone disruptor, detected in breast milk and blood
• Octinoxate — Endocrine disruptor, banned in Hawaii for reef damage
• Homosalate — Accumulates in the body, potential hormone effects

Mineral Filters (Prefer)

• Zinc Oxide — Broad spectrum, sits on top of skin, reef-safe
• Titanium Dioxide — UVB protection, gentle on sensitive skin

What to Look For

1. Active ingredients should be zinc oxide and/or titanium dioxide
2. Avoid aerosol sprays (inhalation risk)
3. Choose SPF 30+ with broad spectrum protection
4. Look for ‘reef safe’ or ‘reef friendly’ (though this isn’t regulated)
