FAQs

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

    Best hydration

    Love this serum! Switched from another brand and wasn’t sure about the gooey texture at first but my skin looks and feels so hydrated, I’ll be buying again!

    Changed formula?

    Dear Osea, did you change the formula of the Hyaluronic Sea Serum? I’ve used this product for 2 years now and have loved it until the last bottle I purchased. I noticed right away that there was a new, kind of dirty scent which was surprising as I was originally drawn to Osea for the lack of fragrance and scents in their products. I kept using the serum in spite of the scent and slowly developed a horrible breakout. I didn’t even really notice it happening until I had red bumps on both cheeks! I used this in conjunction with the Seabiotic cream and once I stopped the hyaluronic serum my skin started to clear. I’m so bummed as I had finally found the one serum that worked wonders for me and now I’ll have to start searching for a replacement. Please let me know if you decide to go back to your original formula and I’ll happily come in back.

    What’s the sound of a sponge absorbing water?

    This product is almost a sound to me. I put it on and just . . . I don’t know the word. My skin just sucks it in like a greedy toddler with an apple juice tippy cup.

    I feel a lift…I think 🤔

    It goes on silky smooth and is easy to apply. Once it dries, it feels firming. But I feel like it’s sitting on top of my skin, not being absorbed as with other serums. Definitely not oily. I follow the serum with an application of moisturizer. When I remove it, I feel the serum is still under there when I splash with water. I know that sounds odd but the layer is there. No breakouts. No irritation. Just not sure it’s doing anything.

    Wanted to love it

    I loved the way it made my skin feel soft and hydrated, however, as someone with acne prone and oily skin it made me break out. I wanted to love it but just not suitable for my skin type!

    Incredible

    I was a little shocked at how noticeable the results were after using this serum for just a few days. My skin is brighter, softer, and just looks healthier overall. Pretty amazing.
