FAQs

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 Collagen 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.

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.

    Hyaluronic sea serum

    This serum is great, compared to other serums I have purchased in the past from other companies. It is lighter and less greasy, making it available to wear during the day instead of applying in the evening.

    I’ve purchased this product multiple times.

    Definitely see a difference in my skin over the months of using this product

    I See a difference with Osea!

    I love this product! I just bought my second time!

    Over the last few years I have been dealing with contact dermatitis. Consequently, I’m limited in what I can put on my face. I’m so grateful for a product that works!!

    Not sure on this one

    I love everything OSEA Malibu, But I’m not so sure I love the scent of this hyaluronic serum. It smells a bit ‘fishy’ like to me.

    I know that hyaluronic acid is extremely popular right now. I’m not saying it doesn’t work, but I use so many OSEA products on my face, I can’t tell if this one is making a huge difference or not.

    But the smell gets to me a bit.

    Skin Feels Great

    The benefits of the serum are clear. It smells a bit off putting but I guess the medicinal smell means it’s good for you haha

    May be a bit sticky for me. I’m still testing things out. Not sure if it compliments my other products or moisturizer
