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.

    LOVED but...

    This was the most amazing Hyaluronic serum ever and used it for many years; however, I am now allergic to Balsam of Peru and this product contains Sodium Benzoate which is a derivative of BoP. Unfortunately, I broke out on my face from using this. BUT if you aren't allergic, it's a must have!

    Wanted to Love

    I wanted to try a new hyaluronic serum and love Osea products so thought I’d try this! And I was not a fan. The dropper was great, much better than the other products I’ve used with a pump. But the smell… no. I would gag every time I put it on. And it made my skin way too greasy looking. I stopped using once I was halfway through the bottle because I couldn’t take the smell and greasy look anymore.

    The Hyaluronic Serum is probably my favorite of all the OSEA Products I’ve used. It leaves my face feeling clean, moisturized and smooth. Thank you OSEA for such a wonderful product!

    Does the job!

    Osea needs to make sure they NEVER stop making this product because it’s just too effective. When I see I’m about to run out, I panic and quickly place another order.☺️
