This is the last and most important step in your morning routine. It’s one of the best ways to protect your skin against premature fine lines and wrinkles as well as skin cancer. Whether you’re running errands or working inside all day, Marine Screen is your daily defense for everyday living.

-Jenefer Palmer, OSEA Founder

FAQs

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. Wears beautifully alone, over moisturizer or under makeup. To minimize white cast, apply over moisturized skin, warm between fingers and gently press in.

Yes, Marine Screen is safe for sensitive skin, dermatologist-tested, and formulated without fragrance. 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.

The Skin Cancer Foundation recommends using a broad spectrum sunscreen with at least SPF 30 or higher for days indoors, and SPF 50 or higher for days outdoors. Because we made Marine Screen to work with your everyday, we chose a higher protection level.

Yes, it should be used everyday, even on days you’re staying indoors! Wearing SPF every day is important because UV rays (particularly UVA rays) can reach your skin even when you are indoors, through windows and natural light. Daily use helps protect against long-term skin damage, premature aging, and discoloration.

Packaging: Tube and cap are made of plastic. Recycling: Please check local recycling guidelines for proper disposal.

    If I could give this 20 stars I would!

    I have been using OSEA for over 10 years and love their products. I have gone through many different sunscreens looking for the perfect one to add to my routine, and while I have found some I like well enough nothing has really stuck as a love. Until now. I can't even explain the perfection this sunscreen is. It's mineral, high zinc but no white caste. Goes on like actual velvet, absorbs quickly and leaves your skin so so soft. I'd like to install a constant pump in my bathroom please and thank you. You all better buy this before I buy out the entire stock!

    The best sunscreen

    I am honestly impressed of how good this has been working for my skin. I like that it doesn’t leave any white cast. In fact it gives a nice healthy glow. Also it feel very lightweight which makes it even more enjoyable. Definitely a must have sunscreen.

    Lightweight and Efficient

    A good sunscreen isn’t easy to find. This one feels good on the skin. It applies and blends evenly and doesn’t leave a white residue, which can be a challenge for me with medium toned skin.

    It’s thick enough that I feel protected from sun exposure, especially here in Hawai`i yet lightweight enough for my skin to breathe.

    The sunscreen we’ve all been dreaming of…

    Sunscreen is something we should all be wearing on sunny or cloudy days, we know that… But, finding the right sunscreen has always been a mission until now. OSEA’s marine sunscreen is not only protecting my skin from UVA/UVB rays, but it is also hydrating it! OSEA’s marine sunscreen also contains hyaluronic acid, which I am a huge fan of - OSEA also carries their Hyaluronic Sea Serum (which is also a must). Having hyaluronic acid in this mineral sunscreen means that my skin is not only being protected from UVA/UVB rays, but also getting the benefits of improved elasticity and keeping fine lines at bay. I am also thankful that OSEA decided to go with an SPF of 50. I also love the packaging as it can fit in most bags for those of us that are on the go. What I love the most is knowing that by using OSEA’s marine sunscreen I know that the ingredients are not only great for my skin (which is our largest organ), but that those ingredients are also clean ingredients and something I trust to put on my face throughout the day. I also have to add that unlike most sunscreens out there, this one does not leave a white residue behind - my skin just soaks it in and on some days I don’t even need anything else besides OSEA’s marine screen. I cannot recommend OSEA’s marine sunscreen enough - try it and find out what a dream come true, mission accomplished (finally finding the right sunscreen) OSEA’s marine screen is- yay!

    Works well, no white cast on skin

    For a mineral sunscreen, it's got a very lightweight feel and no white cast is left on skin. It works well, although is not waterproof or water resistant so not great if you're in hot weather where you'll be sweating.

    Barely there, full coverage

    I have been an Osea fan since they were offered in the "Fab Fit Fun" boxes I was gifted years ago. I love so many of their products for different reasons - my newest favorite is this SPF! Easy to apply, and goes on smoothly - no grease OR residue + is quickly absorbed. Whether I am wearing the SPF on its own (with moisturizer, of course) or adding a some light makeup - I like knowing that I am wearing protection from the sun without physically or visibly seeing it!

    Nice product, good feel on skin

    I like this sunscreen, it goes on like a cream but feels very light; not sticky or greasy … and no scent (which I love). I can’t speak to how the SPF works because it is not yet sunny enough to test in New England. I will definitely be adding this to my skincare routine and beach bag.

    Great sunscreen!

    This has been such a great addition to my sunscreen regime. It is not greasy, and doesn't have the white cast that some

    mineral sunscreens have. It feels good on my face and doesn't just melt off. I live near the beach so I have tried many mineral

    sunscreens brands. The quantity in the tube is comparable to other brands, but the quality is better. I will definitely be supporting this one!
