Apply liberally to face and neck as the last step in your AM skincare routine, at least 15 minutes before sun exposure. Reapply every 2 hours for full SPF protection.

Yes, Marine Screen® is safe for sensitive skin, dermatologist-tested, and formulated without fragrance. It’s also recognized by the National Eczema Association with the Seal of Acceptance™.
The formula is designed to be gentle on all skin types while delivering mineral SPF 50 sun protection and skincare benefits.
This is a mineral SPF, aligning with OSEA’s clean approach to skincare and rigorous ingredient standards. Mineral filters are naturally white powders that sit on top of the skin to form a physical barrier, making it impossible for mineral SPF to be 100% invisible on every skin tone. Marine Screen® was formulated to be lightweight and blendable to help minimize the look of white cast, and blends best when warmed and pressed into well-hydrated, moisturized skin.
Here are some pro tips to help minimize white cast (especially on deeper skin tones):
• Apply over well-moisturized skin for the smoothest blend.
• Warm it between fingers before pressing and smoothing onto skin.
• Let it set for 60–90 seconds before makeup; it layers well under makeup.
Marine Screen® is a silky-smooth, non-greasy formula that melts into skin blending in effortlessly. It includes an olive-derived natural silicone alternative to help deliver its lightweight, non-greasy texture.
To avoid pilling, we recommend waiting 60-90 seconds between the last step of your skincare routine and application of Marine Screen® to ensure each product has the chance to sink in and set fully. Also, wait 60-90 seconds after applying Marine Screen® before applying makeup over it.
"Reef-safe" isn’t a regulated claim with a universally accepted standard, so we do not claim that Marine Screen® is “reef-safe”. However, Marine Screen® is purposefully formulated without oxybenzone, octinoxate or octocrylene-active sunscreen ingredients banned in Hawaii because they are known to be harmful to coral reefs, aligning with OSEA's clean approach to skincare and commitment to our oceans.
