A lightweight alternative to The Ordinary’s {Hyaluronic Acid + B5}, this advanced formulation features marine-derived water reservoirs, which attract and hold moisture, much like hyaluronic acid. Just as advanced as you’d expect from this pioneering skin care range, it’s also enhanced with skin-friendly marine bacteria from Hawaiian red algae and micro-filtered blue-green algae to deliver additional benefits. The exceptionally light-textured formula absorbs instantly, swiftly penetrating skin to deliver its impressive hydrating effects – without leaving a sticky or tacky film.
If you love the heroic hydrating power of hyaluronic acid but want a lightweight alternative, look no further than The Ordinary’s Marine Hyaluronics. Starring weightless marine-derived water reservoirs, the formula attracts and holds moisture just like hyaluronic acid – but feels lighter in texture when you apply it. Designed to be a lightweight alternative to The Ordinary’s {Hyaluronic Acid + B5}, this formula also contains extracts 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 of which work together to offer additional moisture and age-defying effects. Simply apply a few drops of this before creams or heavier formulas to supercharge your hydration weightlessly.
Apply a few drops to face AM and PM before creams.

Light and not sticky
I have tried other hyaluronics which have left my skin sticky after. This one doesn't make you sticky and you actually feel slightly hydrated straightaway.

Hydrating & plumping
The consistency of this product means it’s hard to apply, but I can get past this issue as I love how hydrating & plump this makes my face feel & look. Amazing value skincare.

Hydration boost
This is super watery which makes it a bit weird to apply but it gives a nice boost of hydration before my moisturiser which is definitely needed in colder weather

My favorite TO product
I like the philosophy behind TO products, affordable skincare that works. Marine Hyaluronics is my by far most favorite of their range. I love that it is lightweight. I have purchased this so many times and very strongly recommend.

lightweight little wonder
I used to be addicted to this serum. It is lightweight and it hydrates, plumps and evens complexions. It also clears little blemishes. The smell can be a bit bad but it fades away quickly! My fav product from the ordinary

Sticky but moisturising
A nice before-bedtime product. Rather sticky but hydrating

Hydrating serum
This is my favourite version of hyaluronic acid. It is very watery but I find this helps it absorb into the skin quickly and I much prefer it this way compared to other thicker hyaluronic serums. It plumps and hydrates my skin and because it is very lightweight it works great to layer other serums on top. I have been using this product for years and I absolutely love it!

Not as hydrating as I expected …
Definitely not as sticky or as thick as the original, this is a very watery like texture …almost too watery so not sure how hydrating this will be for my dry skin during winter but if I think it’s a “ “ cool drink of water” for when your skin feels parched or dehydrated . Not sure if I will repurchase though

Hydrating
I tried this as a recommendation from a pharmacist friend to use in the mornings as additional hydration and I have to say I'm very satisfied with the product. It makes my skin look nice.
