After cleansing with your favorite cleanser, like our bestselling Ocean Cleanser, prep skin with Sea Minerals Mist and apply a few drops to slightly damp face and neck. Allow to absorb.
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.
Seaglow Overnight Serum AHA Treatment is our exfoliating serum.
High-performance 9% AHA + 2% Phytic Acid treatment exfoliates to promote skin turnover, which evens tone and texture overnight. Nutrient-rich seaweed and Shiunko oil reinforce skin’s moisture barrier to reveal radiance. Wake up to clearer pores and a smoother, brighter complexion.

- CSCarla S.Rated 5 out of 5 stars8 hours agoGame changer
I have used this for close to 6 months & my skin is softer, looks healthier and with moisturizer applied 15 min after my wrinkles have softened.
It’s like I’ve added a layer of moisture to my skin.
One of my FAVORITE Osea Products
- A“Ashlee “Ash” A.Verified BuyerRated 5 out of 5 stars11 hours agoMy Fav Hyaluronic Serum!
This is the only Hyaluronic Sea Serum I'll use. I've tried multiple brands in the past but didn't see results, and typically, my sensitive skin reacted badly to the other formulas. However, this hyaluronic sea serum has been amazing for my skin! It plumps my skin so fine lines are smoothed out, and I haven't had any dryness. I use it day and night, and it is now a staple item in my skincare routine. My skin craves Osea products - it has never looked better after switching my entire skincare routine to their products.
- JGJaime G.Verified BuyerRated 5 out of 5 stars19 hours agoMy go to morning and night!
Love, love, love this hyaluronic and will forever use as my base, morning and night! Glides on smoothly and hydrates unbelievably well!
- ECElizabeth C.Verified BuyerRated 5 out of 5 starsYesterdayLove this for anti-aging and rosacea.
I have been using this every AM and PM under my moisturizer for several years. It is the only product which keeps my rosacea in check. I sometimes add a few drops of tea tree oil if I'm having a flare up. Makeup goes on right over this like a dream. Great product, thank you!
- DTDebra T.Verified BuyerRated 5 out of 5 starsYesterdayThe Best
A staple in my skin care routine. Very hydrating.
- CHCatie H.Verified BuyerRated 5 out of 5 starsYesterdayMy favorite serum!
I've tried many different serums but this is by far my favorite. Visible results!
- ARAmy R.Verified BuyerRated 5 out of 5 starsYesterdayHyaluronic Sea Serum
When I first started using this product, I thought it might be drying out my skin and quickly stopped using it. However, I gave it a second chance and I'm so glad I did. I've now been using this serum for quite some time and really think it adds a lot of moisture to my face and neck area. It's a must part of my nightly regime and I wouldn't go without it!
- KSKyna S.Verified BuyerRated 5 out of 5 starsYesterdayWorks
This is the one step of my routine that I will never be without. I noticed a difference in the plumpness of my skin once I started using this.
- CChrisVerified BuyerRated 5 out of 5 starsYesterdayBetter than moisturizer
This serum is a game changer in facial hydration. It dries with a soft moisture finish and I add my moisturizer over it which creates the best natural shine. Moisturizer alone does not give this look. My makeup sets better and the overall look of my skin has improved
- KKatVerified BuyerRated 5 out of 5 starsYesterdayGood product
I’ve always used a face serum and began using Hyaluronic Sea Serum several years ago when I switched over from Lancolm to Osea for their natural ingredients. I’m quite satisfied with the product and will continue to use it .
