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.

Smoothed and moisturised skin
I've been using this for about a month now and my skin feels smoother, softer and more moisturised. I have dry and sensitive skin and this product has made a positive difference. However, there is sometimes mild redness and itching when I apply the product but this fades in under an hour. My skin feels uncomfortably tight immediately after application but this goes away as it's absorbed and leaves my skin feeling baby soft. Overall, I'd recommend this product if you struggle with very dry, itchy skin. Unlike other moisturising serums I've tried, it doesn't leave my skin overly oily and is absorbed well. The changes weren't immediate though; it took several weeks of daily use to make any difference. If you're going to buy this product don't expect immediate results.

Amazing alternative to hyaluronic acid!
Having had many issues with hyaluronic acid causing my skin to break out, I was really excited to try this as an alternative. The texture is almost like water but sinks in really effectively. After just one day of using this product, my skin feels more hydrated and looks significantly plumper than it did before. A really lovely product that is easy to integrate into existing skincare routines, highly recommend!

Amazing for combo skin
I love this so much and so much more than The Ordinary's Hyaluronic Acid 2% + B5. The texture is so much nicer and not sticky, with no tendency to pill. Just remember to always apply on to damp/just misted/post-essence skin, as with all hydrating serums if you really want to see all benefits! This is so underrated, but I just think people don't use it properly!

A new staple in my routine
I'm currently on my second bottle and I love it. My skin did react to it in the beginning but after it got used to it, it became a saviour for my surface-dry skin. I love how lightweight it is, as the consistency is almost water-like. It sinks in very quickly and will not affect the products you layer on top. A downside of the thin consistency is that I go through this quite fast. I would choose this over the Vichy hyaluronic booster (that many rave about) in a heartbeat, as I find this to be more effective and it is a fraction of the price.

Nice
Tried this one instead of the HA + B5 which is what I would usually go for. Much more of a watery consistency however I felt as though this sunk into my skin amazingly. Found it more difficult to hold the product in my hand and press onto my skin hence giving it a 4 star, however would still recommend as my skin definitely felt more hydrated. (Used this after cleansing, and toner.)

Great for dry skin!
This serum is lightweight and hydrating. I fell in love with this product once I had put it on my face. I have dry to combination skin and this gave my dry patches that extra moisture boost they needed.

Transformed my skin
I have suffered with moderate acne since I was a teenager, I read somewhere that the key to solving most skincare issues is hydration, so I thought I'd give this a try. I had used the regular hyaluranic acid before trying this and I wasn't too impressed, the consistency was much too heavy. This product is totally different, it has the same consistency as water and it spreads easily all over my face and even my neck. The key is making sure your face is damp before you apply the serum, either with water or a hydrating toner, if you don't do this you won't see the benefits. I've been using this since march and my skin has never been clearer, I've also a noticed a reduction in redness/texture and overall irritation, I'd recommend this to anyone! x

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!
