Stream2Sea’s SPF 30 sport sunscreen is built for divers, snorkelers, surfers, and adventurers spending long hours outdoors. It offers broad-spectrum UVA/UVB coverage and extended water resistance to keep you protected through active use. Every formula is biodegradable, mineral-based, and scientifically proven safe for reefs and aquatic life.

Key Benefits

• High-performance coverage SPF 30 delivers stronger UV defense for extended exposure.
• Reef-safer science Tested safe for coral reefs, fish, and ecosystems.
• Water-resistant Effective protection during swimming, diving, or sweating.
• Durable wear Designed to stay on in active conditions.

How to Apply

• Apply generously 15 minutes before activity.
• Use approximately one ounce (a shot glass full) for full-body coverage.
• Blend in evenly—mineral sunscreens work by sitting on top of the skin as a physical barrier rather than absorbing like chemical sunscreens. This can leave a slight white cast until fully rubbed in.
• Reapply every 80 minutes when swimming or sweating, or every 2 hours during continuous sun exposure.

Mineral vs. Traditional Sunscreens

Unlike chemical sunscreens, which absorb into the skin and convert UV rays into heat, mineral sunscreens use natural minerals like zinc oxide to reflect and scatter UV rays. This difference means they start working immediately, are less likely to irritate sensitive skin, and are far safer for coral reefs and marine life. The trade-off is a slightly thicker texture that requires more careful blending—but this is the same quality that makes them stay in place in the water and provide more reliable protection.
