The Ordinary Marine Hyaluronics by The Ordinary

Overview

The Ordinary Marine Hyaluronics is a lightweight marine-derived water that helps to lock moisture in your skin, much like a Hyaluronic Acid does. The difference? The consistency of the Marine Hyaluronics is thinner and lighter, more like water than a typical serum texture. This facial serum helps to attract and hold water in the skin, ensuring your complexion remains plump and hydrated throughout the day. This product is fast absorbing, suitable for all skin types and should be used before facial creams. 

Features and benefits of The Ordinary Marine Hyaluronics: 

  • A lightweight hydrating serum
  • Water like consistency
  • Provides lasting moisture
  • Promotes a smooth, plump complexion
  • Nourishes skin
  • Scented, however, disappears after a few minutes after application
  • Silicone, alcohol and oil free
  • Vegan and cruelty-free
  • 30ml
 
The formula contains exopolysaccharides from skin-friendly marine bacteria, Hawaiian red algae, Glycoproteins from Antarctic marine sources, micro-filtered blue-green algae and several health-supporting amino acids. All marine derivatives in Marine Hyaluronics are sourced sustainably. The total concentration of active ingredients in this formula is 23%. 

This formula is exceptionally light in texture. If you prefer a thicker consistency, try the Hyaluronic Acid 2% + B5.


All of our products are filled/measured by weight/volume so the product is correctly filled to 30ml. The packaging does not accurately reflect the size of the fill. However, this is intentional as some air must be allowed at the top for the product to actually close.

Gentle on skin but does the job! - 17-01-2019 by

I have oily acne prone skin, but got very dehydrated this winter. This helped hydrate my skin lightly and made it so much better! I like to use gentle products and this is a great, lighter alternative to hyaluronic acid.

Hydrating - 10-01-2019 by

It absorbs instantly. I notice the moisturizing effects when I forget it and my skin feels dry. I don't notice any weird smell unless I bring it right up to my nose, even then it isn't overwhelming.

Stank But Dank - 03-01-2019 by

It smells. Yeah, kind of gross. It also has a really watery consistency, so it's like rubbing water on your face. Weird, I know. Do I even like it? Yeah actually, better than the Hyaluronic 2% because it doesn't leave me feeling sticky af. I usually always wear a hyaluronic acid and this particular one lives at my bf's house. I put it on morning and night and never really see a difference compared to my hadalabo one I use at home. It doesn't feel like you're doing much when you're applying i but I forgot to put it on one day and my skin got SO DRY. If you can get past the smell and the feeling you're doing nothing, you'd probably love it. I don't even use my 2% because it makes me feel sticky and this dries to nothing.

Hit and miss - 25-12-2018 by

Ok is hydrating but has very strong smell i prefer the HYALURONIC ACID 2% + B5.

Marine vs Hyaluronic Serum - 18-12-2018 by

Selecting between The Ordinary Hyaluronic serum and the marine serum I would go hyaluronic- nicer consistency, smell and I feel it applies better. This product is great but I prefer the hyaluronic.

Still my favourite hydrator (Review after 1.5 months) - 18-12-2018 by

I have been using this for more than 1.5 months and it is a staple in my routine now. I really like how light and watery it is. It dries down to nothing and causes no pilling. It also hydrates my skin and can act as a buffer if I’m using strong actives. Overall a fantastic product.

Best hyaluronic prodcut i've used - 14-12-2018 by

It's a lot thinner than the other Ordinary hyaluronic acid with no tacky residue. It also absorbs quicker and feels much lighter on the skin - great for summer!
There is a weird smell but it goes away once absorbed.

Very good if you don't mind the smell - 13-12-2018 by

This has a really thin, watery consistency so it works really well as a hydrating lotion before other treatments. It absorbs quickly and sits well under other products. The only downside is that it smells a little funky. To me, it smells a bit like cheese or something that has fermented!

Love it - 13-12-2018 by

I've used half a bottle of Marine Hy and use it as the first step after cleansing, both AM + PM. It is very lightweight and I experienced no irritation. No problem with the smell, it hasn't bothered me at all.

Not a keeper - 13-12-2018 by

As with all The Ordinairy products the price is good but I’m not a fan. It feels weird, greasy or something. And the smell...! Really unpleasant. Plus I didn’t notice any effect. Won’t repurchase.

Refreshing but not as satisfying as HA 2% - 20-11-2018 by

I'm a big fan of The Ordinary Hyaluronic Acid 2% + B5 so I thought I'd try another HA. The consistency is completely different, as thin as water rather than a thicker serum, so it doesn’t quite feel as satisfying when you put it on. But it does sink into my normal skin very quickly, so that’s a positive. I haven’t noticed any particularly positive or negative results, so I’ll finish off the bottle but will stick with the 2% in future.

Does the job and great price - 19-11-2018 by

I used the original TO Hyaluronic and I definitely prefer the texture of this one, it seems to absorb quicker and feels less sticky which is nice. It has a bit of an off scent but nothing too worrying. Great for the price, lovely under the rest of my skincare.

Hydrating - 12-11-2018 by

Good lightweight hydration but it’s smells!

Lightweight moisturiser - 02-11-2018 by

This is a great moisturiser especially if you have oily and acne prone skin like myself. I use this under makeup to add a touch of moisture. It does have a weird smell but it goes away almost instantly.

Smelly - 31-10-2018 by

It's very lightweight and I prefer it to the original hyaluronic acid, but its really super smelly. Have to hold my breath when applying it, but at least the smell goes away quickly. That said, I don't find it exceptionally hydrating for my dry skin.

Good additional moisture barrier - 25-10-2018 by

Found this product really good and hydrating for my skin

Hydrating but not too heavy - 24-10-2018 by

I have combination skin and sometimes my cheek could be quite dry. However, I hate the stickiness after putting on heavy cream. This product suits my need very well. It provides proper hydration for my skin while not making it too oily or sticky. Some people complain about the smell. I do notice some smell (like cheese) but I can totally accept that. I would highly recommend this product to anyone that does not have a toner/essence and is worried about putting on heavy products on your face.

Better than the hyaluronic - 03-10-2018 by

This is a good product. It goes on easily (the smell disappears pretty quickly) and it absorbs into the skin quite well. It is moisturising but possibly could be more moisturising.

smelly but good for moisture - 26-09-2018 by

I bought this because the weather is getting warm. This product is smelly, but is quite effective for moisture.

Ok so far - 20-09-2018 by

I decided to give this one a go instead of the The Ordinary Hyaluronic Acid 2% + B5 this time around as I have been using the latter for a while. This one is very runny but I do like that it is not sticky. I spray some toner onto my face and apply and it sinks in well. I have oily/combo skin and I am not entirely sure this makes a huge difference to my skin's hydration, but I still enjoy the process and feeling on my skin.

Summer hydro - 18-09-2018 by

I love anything that helps with my dry skin so I'm a big hyaluronics lover, but in summer I can see it could feel a bit thick and stuffy so I'm really happy I found this as it does the same to my skin as the thicker serum but feels more summer friendly. Often thin creams aren't as good as thick ones on dry skin but so far I feel this one does the same so hopefully it does over long term use throughout summer as it will save my skin big time.

Good Light Moisturisation - 13-09-2018 by

This delivers light moisture to the skin and is well suited for hot humid and tropical climates.

Good but smells - 09-09-2018 by

I love that it's quite watery and hydrating. My skin soaks it up immediately! I just don't like the way it smells.

Nice! - 06-09-2018 by

This is very hydrating! The only issue is that it’s extremely watery!

Nice consistency and hydration - 31-08-2018 by

I have the oily t-zone, dry everywhere else type skin with fine lines. This is nice and thin, I apply a few drops to damp skin and the spray with a mist (avene spray) to get those water absorbing molecules to do their thing! No irritation so far and absorbs quickly with no sticky ness after.

Loving This Range - 22-08-2018 by

I did a bit of research, directly on TO website to determine which skincare products are suitable for me, to create a unique solution to look after my face. I chose this product due to its hydration properties, something that skin starts to lack when you age. I love how the product smooths out across the face. Don’t let the minute smell turn you away, it’s a very light smell and disappears in seconds.

Quick-fix hydration that disappears without a trace - 21-08-2018 by

I have dry skin (more so in winter) and this serum has found a regular place in my routine. It's super light and watery and disappears almost instantly. Unlike other hyaluronic serums, it's not sticky and almost disappears without a trace. I only gave it 4 stars as I'm not sure if it is helping my skin in the long term but for a quick-fix hydration boost that layers will with other serums, this is a good one to try. I have not noticed the unpleasant smell that some other reviews have mentioned. It does have a smell, but I don't find it strong or overpowering and it disappears very quickly (almost instantly). I actually like that The Ordinary don't use artificial fragrances to mask the natural smell of the ingredients in their products.

Clear skin - 20-08-2018 by

Iv been using this for maybe couple months now and I have noticed that I am no longer getting breakouts. I may get the odd lil bump but it’s nothing to worry about, also my skin seems to be a lot more even tone that could be cause it’s hydrating my skin & it’s more healthy another the smell I reckon it’s really that bad i didn’t know what people are going on about, it’s there for a second so don’t let that stop you from trying this little beauty out. Definitely will be continuing to use this

Deeply hydrating and quick absorbing - love! - 20-08-2018 by

A wonderful light-weight yet highly effective hydrating serum. It has a water-like texture, soaks in quickly and my skin just drinks it up. I use it both morning and night and even on the backs of my very dry hands. There is a mild smell upon application- similar to turned milk which may be off putting for some but doesn’t bother me at all. It fades extremely quickly and the outstanding results of this serum are worth it! A definite repeat buy for me.

Loved it, but... - 17-08-2018 by

I have combination dry to oily skin so finding a moisturiser that isn't too dry but isn't too oily can be a nightmare! This proved to be a perfect addition to my daily skin routine, giving my skin that little bit of extra moisture it needs without leaving me oily. On a normal day I will only use this product once a day, but if I'm feeling a little on the dry side I'll add it to morning routine as well. The only down side to this product is the initial smell (the reason I am giving it 4 stars). That being said you do get used to it, and it's a small price to pay for a good product.

Light weight nourishment for all skin types - 13-08-2018 by

Love love this one. Was very excited to see that TO was venturing into marine botanicals and it doesn't disapoint. Very light, watery consistency. Absorbs super fast. Has the advantage of not pilling the way TO Hyaluronic acid does. Layers in beautifully and nourishes my rosacea prone sensitive skin.

I've read a few negative reviews de to the smell.. firstly; it's more of a vinegary-briney ocean type scent. Its very faint. Secondly; the smell is gone within seconds. You get used to it very quickly, especially given the benefits your skin will reap.

I just purchased this and I am already in love with it. - 13-08-2018 by

This product glides on to my face and dries almost instantly leaving a non sticky plumpness which seems to last. If you find it sticky you are probably using too much product at once. The handy dropper gives an indication of how much to use.

Unpleasant smell - 13-08-2018 by

I have dry skin and bought this upon recommendation of a friend to purchase hyaluronic acid. While this seemed to have boosted moisture levels, it smelled very strongly and unpleasant. My husband thought I smelled like a tuna sandwich, so I can't use it around him anymore!

Loved it - 20-07-2018 by

Lightweight and quicker to absorb than the other HA serum, but the smell takes a little getting used to... luckily, it fares from the skin pretty quickly. Unsure if I'm fully coverted from the other TO HA serum, but we'll see...

Brilliant - 18-07-2018 by

This serum is incredibly light weight but does an amazing job. I know add this serum to my morning routine

Awesome but smelly - 17-07-2018 by

I use this together with their other hyaluronic b5 serum and it’s great although it really smells like dried up milk vomit on a bib

Runny consistency but works well. - 02-07-2018 by

Does a good job of hydrating the skin but it is very runny so it is not as easy to apply as the thicker serums.

Nice and lightweight - 13-06-2018 by

I have dehydrated, combination skin and I like this a lot! If the Hyaluronic Acid 2% + B5 did not work for you because of it's sticky texture and pilling etc, this will be a great substitute. It's not hydrating enough on it's own, so I use it before a moisturiser.

Hydrating - 25-05-2018 by

Very hydrating but light, I love the product but the water consistency is hard to apply. It does smell a bit if you put it right to your nose, but the smell does not linger at all once absorbed, which is almost instantly upon application. I love to use this around my eyes.

Get this product!! - 24-05-2018 by

Absolutely love this product, except smelly a little... But so good to use! Will buy again

Amazing if you can get past the smell - 23-05-2018 by

This is so good. It's like the HA + B5 but less sticky! Great for the hot months when you don't want that extra stickiness. It's like a water formula, soaks in instantly! The smell does go away once it's soaked in. I reallllly like how hydrating this feels.

Buy it! - 18-05-2018 by

1. It smells bad. Real bad. But either I’m getting used to it or the smell seems to have gone away idk, but it’s something I’m willing to endure cuz of all the good things this has done to my skin.
2. I’ve been using this for just 1 week and my skin has gone from super dry and inflamed to calm and plump. Did I mention I don’t use this with any other moisturiser/cream/whatever else? As a person with oily skin I’m almost afraid of moisturisers because they tend to add to the shine which is why I chose this for its super light formula but boy don’t let that fool you cuz this has been one of the most hydrating serums I’ve ever come across.
3. Buy it!

Smelly but good - 17-05-2018 by

When my bottle of this first arrived, I was about to email the company to ask if had gone "off" due to the weird smell (which is something between parmesan cheese and dirty feet). However, a quick check of their website revealed that everyone was commenting on the same thing! It doesn't smell "marine" like the ocean, more like rotting algae.

Yes, it stinks, but the smell doesn't last long on the skin, if at all. The hyaluronic formula is a lot lighter and less "sticky" than The Ordinary's Hyaluronic Acid 2% + B5, so it is a good option for the hotter (greasier) weather. It absorbs a lot faster and apparently has a larger molecule size, so hydrates the upper layers of the skin.

It's good stuff, despite the smell.

Very light texture - 11-05-2018 by

This is a very light, water like formula. Less sticky feeling than the hyaluronic acid 2% + B5, but I hate the smell of this. It does go away once absorbed but it stinks.
