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.

    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.

    Love it

    I visibly noticed a difference in the look and feel of my skin shortly after using this, esp my '11s' between my eyebrows. It goes on & absorbs so nicely and I love that ot doesn't really have any smell. I usually just use it at night before my moisturizer. Definitely a regular part of my skincare routine!

    So necessary

    This is one of those products that silently and subtlety works it’s magic. I didn’t think it was really doing anything at first, but when I stopped using it I noticed my skin would dry out more quickly during the day and was just drier overall. I feel that it helps my moisturizer soak in and last longer.
