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. Need we say anymore?

Another TO staple
I can't be without this. I use it AM and PM as the first stage of my routine after cleansing and toning. It is perfect for preparing my skin to quench other products be it serum, moisturiser, or retinol.

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
