Details & care
What it is: An exceptionally lightweight serum that acts as a hyaluronic-acid alternative, which directs water where you need it most.
What it does: By combining exopolysaccharides from skin-friendly marine bacteria, Hawaii red algae, glycoproteins from Antarctic marine sources, micro-filtered blue-green algae and several amino acids, this water-based formula targets hydration below the skin's surface, resulting in a softer, plumper complexion.
How to use: Apply a few drops to the face in the morning and evening. If irritation occurs, rinse off, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children. The serum is good for 12 months after opening.

I swear by this stuff
I’ve never gotten compliments on my skin before but this product changed that! It hydrates and shines my skin with no oily texture whatsoever, it’s almost like I’m not wearing anything. It gives a glow and clean feeling that you get after taking off a good face mask. I wish they made this in a larger bottle as I go through it so fast!

It's just water?
I thought this would moisturise my skin or at least help it along whilst still using my main facial moisturiser...this is literally just plain old water, it does nothing. Zero. It's one of the cheaper items on here but honestly don't waste any of your money!

Is this just water?
This really is just like water. Really hard to get it on your face without spilling it. I think it would be so much better if it was in a spray bottle to mist on. Not sure if this is doing anything to my skin, but I will buy an empty spray bottle, transfer it and see what happens.

Good
The Marine Hyaluronic Serum is a lightweight product that absorbs into the skin quickly. It delivers hydration and a beautiful glow to your face. I like to use this before makeup so that my base is flawless. Overall, I really recommend if you are looking for hydration and dewiness in your skincare routine.

Good hydration
I like this marine hyaluronics. It's literally like a bottle of water so be very careful when you apply. I think it provides a good lightweight step in my morning hydration routine. Great value and no irritation. I would say this is the only product I actually apply "pipette to face" otherwise you lose it between your fingers

Light Yet Deeply Quenching
A water-light serum that layers effortlessly and leaves skin plump without any stickiness. Ideal for oily or combo types needing hydration without heaviness. Absorbs fast and plays well under other products, making it a daily staple for a refreshed, dewy look.

Lovely product
I’ve struggled with hyaluronic acid products in the past. Yes, they hydrate, but most of the ones I’ve tried leave a sticky feeling on the skin and/or pill under makeup so I only use them at night and even then, they’re not that pleasant.
However, this product has a texture like water, but it leaves your skin feeling hydrated yet it’s not in the least bit sticky and anything sits perfectly on top. I absolutely love this.
