The Ordinary has firmly cemented itself as a leader in science-backed skin care. Taking the guesswork out of building a regime, it ditches unnecessary, filler ingredients for familiar, hard-working actives that deliver promising results. If you love the heroic hydrating power of hyaluronic acid (we're talking locking in ultimate moisture to your complexion) but want a lightweight alternative, look no further than The Ordinary's Marine Hyaluronics (30ml).
Intensely hydrate and nourish your complexion with the Marine Hyaluronics (30ml) from The Ordinary.
Designed to be a lightweight alternative to The Ordinary's Hyaluronic Acid + B5 (sold separately), this formula attracts and holds moisture just like hyaluronic acid, but lighter in texture. Starring *deep breathe* marine bacteria, Hawaiian red algae, glycoproteins from Antarctic marine sources, micro-filtered blue-green algae and amino acids, it attracts and holds water to leave your complexion looking plump and moisturised.

Love
I love this stuff!!! It is so lightweight and just sinks into my skin really quickly. It is a real nice addition to my skin care routine. Best to pipette into hands and smooth on face as the consistency is very watery. I can’t notice a smell like so many others have commented. Will be purchasing more the minute this comes back in stock!

My favourite
Very hydrating, I love the watery texture. The smell really reminds me of sea a little bit. (I have combo skin prone to acne, little bit on the sensitive skin side)

Antioxidants plus lightweight hydration. Superb!
I just love this. You can't get these algae based antioxidants at this price and in such a lightweight formulation that my skin simply drinks in. I can then layer other products on top or go straight to makeup. Fabulous!

Meh
No issue with a smell, however, it is so watery that I am losing half of it on my dressing table every morning. Purchased as my normal HA from Inkey List was out of stock, I will be patient next time and wait for it to be restocked rather then rebuy Marine Hyaluronic.

Keep going
I've noticed people saying this smells, mine doesn't and there is no residue at all. It's just like rubbing water on your face. At first I was put off with it being a water, found it hard to apply with the pipet on my face as it's just trickles down. I was going to give up but then I started putting it in my hands and then rubbing it in, also applying quite a bit as it's so cheap you can afford to use more than usual and I can see now I've nearly finished the bottle that it definitely is worth repurchasing, it has worked well. If you don't like sticky serums then this was made for you.

Marine hyaluronics
A great product I have been using it for a while now. It plumps and hydrates my skin perfectly. Yes as other reviewers say the smell is not that great but it does not last that long. I think some people are missing the point of The Ordinary products, they are the products you find in expensive brands in their purest form without the nice smells added as well as other stuff to the products which bump up the price significantly. Great products that do the job as well as some of the high end products I have previously used, don’t be put off by the smell .

I love this product. It’s not sticky like other HA products I’ve used. I see a lot of comments about a smell, I haven’t noticed any smell at all with mine.
