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 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.

Hyaluronic Sea Serum is your clinically proven anti-aging moisture boost.
This fast-absorbing, anti-aging serum is clinically proven to smooth the appearance of all lines and deliver a lifted, firmer look. Two molecular weights of hyaluronic acid, seaweed and snow mushroom, work together to restore and maintain optimal moisture levels, keeping your skin hydrated, plump and dewy any time of day. Clinically and dermatologist tested.

Dream Night Serum is a powerful seaweed-infused formula combining two firming peptides + algae-derived bio retinol. This serum visibly reduces crow’s feet, fine lines, wrinkles and even deeper wrinkles as your skin ages!

    Best ever

    It's always been very important for me to take care of my skin. I don't wear make-up but I use skin care products. I've tried several different brands but this one is the best product and brand that I've come across. Im only sorry that I've waited so long to try due to the price. It is worth evey penny; I love all the products I've tried.

    The best!

    This Hyaluronic Sea Serum is my favorite that I have tried of any brand. My skin looks and feels so good when I use it. I use this every day in the mornings and use the Dream Night Serum in the PM. I actually prefer this one between the two, but will continue to use both.

    Like it but expensive!

    This goes on nice, doesn't smell, leaves my face feeling moisturized. However, as a retired individual, I do not know if I can continue to purchase this item. I seem to be going through it quickly, and I don't even fill up the dropper.

    Smooth and Soft

    Leaves skin smooth and soft. It’s almost sticky until you work in the product.

    Luxurious feel

    This is a wonderful serum that feels so good to apply. A little goes a long way. I am currently experimenting with the body sea serum: one arm treated, the other not. Will follow up with results at a later date.
