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.

Great alternative to HA
If you wanna try sth other than HA, this serum is a good try, have a little bit thicker consistency

Skincare Staple
I was recommended this by a friend, to help with my constantly tight and dehydrated skin. Its much more fluid that the other hyaluronic products I've used before so look a little getting used to. It so light I feel like it absorbs into my skin straight away leaving it feeling comfortable, hydrated and most importantly, not sticky!

Hydrating
Really good serum but extremely watery which I don’t mind but just be aware that it’s not like most serums which are a thicker consistency. Very hydrating and doesn’t pill under other skincare products

Just what I was looking for
Thought most hyaluronic serums were the same consistency until I saw that The Ordinary did a lightweight option still in the strength I was looking for. Arrived promptly and in time for my holiday. Really pleased with purchase.

Staple product in my routine
I used to use the regular formulation of hyaluronic acid from The Ordinary but thought I’d try this one. It’s so much better, it’s not tacky, it’s more of a watery consistency. Dries quicker and mixes well with other serums. Will stick with this now.

Very light weight
This is my 3 bottle i love it, great for sensitive skin especially if you can't use hyaluronic acid but you want some hydration, it's like putting water on your face

Lovely subtle hydrator
When I first used this, I thought it wasn't doing much for my skin, but when I stopped using it, I found it missed it, so I've since reordered the product. As others have said, this is a very runny, non-sticky serum. It honestly feels like water when you apply it to your face. It does, however, do a good job of hydrating my dry and mature skin and making it a little plumper -- more so than The Ordinary's other hyaluronic acid serum, I think, although I like that one, as well. I get the impression my fine lines are less deep when I use this. In combination with a bit of oil or moisturiser this works beautifully.

Thank God
Now I am not one to write reviews but I thought this might help someone. I was using The Ordinary Hyaluronic Acid then I found this. I have oily/combo skin but I need all the moisture I can get otherwise my skin starts to overproduce oil and breaks out. This is my new holy grail.

Heaven sent
I lost count on how many times I have purchased this serum. It's the best hyaluronic acid out there. It's very watery (which I love because I have oily skin) so keep that in mind if you like more sticky serums. I love the texture I love the plump it gives to my skin. I just LOVE LOVE LOVE this. I just wish it came in a bigger size.
