How to Choose
When selecting a biodegradable sunscreen, start by checking the active filter. Non‑nano zinc oxide and titanium dioxide are the only mineral ingredients proven to be reef‑safe and gentle on sensitive skin. Look for certifications such as USDA organic, NSF sport or cruelty‑free labels to verify the brand’s environmental commitments.
Consider the texture and application method that fits your routine. Creams and lotions provide a moisturising barrier for dry skin, while sprays and gels are convenient for on‑the‑go use. Finally, review the water‑resistance rating; a minimum of 80 minutes is recommended for swimming or heavy sweating to ensure continuous protection.
