FAQs

Seal in hydration with your moisturizer of choice, like Seabiotic® Water Cream during the day and Dream Night Cream at night.

Our skincare products are made with naturally derived ingredients to provide the best benefits for your skin. Hyaluronic Sea Serum is fragrance free meaning there is no fragrance or essential oils added. However, one may detect a scent from some of the naturally derived ingredients in this formula.

One’s olfactory receptors (or sense of smell) differ from person to person so it is hard to describe what you might smell in a fragrance-free formula, but it could best be described as a bit “earthy” or “medicinal”. Please note the scent does not affect the product’s quality or efficacy.

    The best!

    I love this serum. I do recommend a few drops at a time because the full dropper leaves much excess & that’s with use for my face to décolletage. Goes on smoothly, doesn’t feel sticky and the effects are hydrating & calming. Really worth it. I use it am & pm under my eye routine, sunscreen & moisturizers. You’ll notice a difference. I tried the anti-aging version & as good as that one is, this is my absolute favorite. Feels & looks like you’ve been for a facial.

    Great!! Results are phenomenal! Makes my skin soft and smooth! I can see the difference in my pores when I use the Hyaluronic Sea Serum vs when I don’t use it. I stopped for awhile then started again because one it’s good for my skin and two it nourishes my pores.
