Boosts skin’s natural glow

Marina Concentrate is a potent treatment that delivers oil-based actives to boost radiance, balance the skin’s microbiome, and provide an instant glow—with benefits seen even in one use. It enhances skin texture, hydration, and overall vibrancy for a fresh, glowing complexion.
Use it like any treatment. After cleansing and toning, apply a few drops of Marina Concentrate to your face and gently press it in. If layering, apply serums first, then your concentrate, and finish with a moisturizer. For an instant glow, use up to twice daily or as needed. You can also mix a few drops into toners, serums, or moisturizers to streamline your routine and boost results.
Concentrates are highly potent treatments that deliver a concentrated dose of oil-based active ingredients, while serums typically deliver water-based actives. Serums are ideal for daily use, whereas concentrates work faster and don't require daily application. Our concentrates can be used daily (a few drops go a long way), with their full power revealed through regular use. They have a richer, oil-based texture and should be applied after serums and before moisturizers. Additionally, concentrates are great for skincare cocktails—add them to toners, serums, or moisturizers for extra benefits and convenience.
Marina can be used daily, both morning and night, for an instant glow and to promote long-term skin balance. It’s gentle enough for daily use and can be layered or blended with other treatments in your routine.

Absolutely! Marina Concentrate works beautifully with other Earth Harbor products. If you're using active treatments or serums, apply those first, then follow with your concentrate, finishing with moisturizer for optimal hydration and radiance. For added convenience, you can also mix a few drops of the concentrate into other products to streamline your routine and boost results.
Yes! Marina Concentrate is perfect for sensitive and reactive skin. Its hydrating and microbiome-balancing ingredients soothe irritation and help promote clarity, all while supporting a healthy glow—without clogging pores or causing breakouts.
Many users notice an instant glow and improvement in skin texture after the first application. With regular use, Marina Concentrate helps balance skin, even out tone, and boost radiance over time.
For daytime, pair Marina with Mermaid Milk Moisturizer for creamy, balancing hydration and Celestine Serum to smooth and improve elasticity. At night, use Luna Rain Serum to exfoliate and refine skin, and Mermaid Moon Balm Cream to hydrate and restore the barrier. Together, these products promote balance and radiance.

Incredible
This is lovely for soothing any redness. I can even use alone for light/quick moisture on the go! My husband can even use it as an aftershave on his crazy sensitive skin! This stuff does it all.

This has faded my dark spots to the point that they are hidden easily by foundation. I can't wait to see them all the way gone.

Love this stuff for my senior skin
Applying Marina concentrate after washing with the sunny dew oil just makes my senior face feel terrific and feel so soft. I have been using these two in combination for 6 most and can really tell the difference in texture and softening of those little lines.
