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?

Staple in my routine
Does what it's supposed to for a great price. It's one of the 4 products I put on my face when going out.

Superb product
I use this as my first layer of skincare after cleansing my face. It's a very watery serum and sinks in immediately. This locks in the moisture really well, I'd recommend using more viscous serums after this one and finishing with a moisturiser.

Hydrating water
An absolute staple in my skincare regime- I apply to a damp face and then layer on other serums. It does take getting used to as it is just like water - except it is so hydrating. It dries immediately with no stickiness so you can get on immediately to your next layering serum.

Skin drinks it up!
This is like giving your skin the drink it’s always needed, super lightweight, almost the texture of water, so soothing and moisturising on the skin

Love, love, love TO Marine Hyaluronics
I love TO Marine Hyaluronics. I am in my third bottle already. It is light and not sticky at all. I use it after toner while my skin is still damp and follow with a moisturiser. It is a beautiful product.

Awesome
I am never without this miracle of a product! I also got my husband hooked on this. Its great that this is fragrance free. So nothing too empowering even for men. I personally love this and feel this definitely has its place in my skincare routine.. love layering this with my other products and i swear this helps my skin stay hydrated

Weirdly effective
This product is so peculiar as it is barely any 'thicker' than water, so can be a little more difficult to get from bottle to face. There is a pipette for you to control how much you get out of the bottle at any given time, so don't worry about ease of use. Distribution issues aside, my skin loves this product with its moistuising ability at the forefront. The products from The Ordinary are all very well priced and are great to give a try whether you're on a budget or not.

Fantastic product, especially for summer
I really like marine hyaluronics. Amazing hydration but ultra light texture, it's like water so you need to be careful when applying. I put a couple of drops and extend it with the other hand so I dont waste product. Simple, wonderful and no conflicts with other products whatsoever
