Description
Description
Nineteen ingredients and not an oil among them. Organic aloe leaf juice opens the list, Sodium PCA sits fifth and water doesn't appear until sixth — which is the short version of why a gel this light still does something.
The part people miss is the algin. It's derived from seaweed, and with cellulose gum it forms a fine film across the skin that slows water escaping — the moisture-locking business the name refers to, and an actual mechanism rather than a phrase. Hyaluronic acid appears in two molecular weights, with three plant sugars and organic sage and white tea. 99% natural origin, certified COSMOS Natural by Ecocert.
How to use
How to use
A thin layer on clean skin, ideally while it's still slightly damp — humectants take water from whatever's nearest and would rather have it from your face than the room. It sinks in within about ten seconds.
It can go around the eye area, carefully, though not into the eye itself. If your skin is dry, put a cream over the top; on normal or oily skin it works as the only thing you need after cleansing.
Who is it for?
Who is it for?
Dehydrated skin of any type, and particularly anyone who wants hydration with nothing rich involved. Because there's no oil in it at all, it suits oily skin as comfortably as it suits mature skin, and it layers under anything without interfering.
If your skin is genuinely dry rather than dehydrated, treat this as a step rather than a finish and follow it with a cream. It's scented, but nothing in the formula has to be declared as an allergen. Gluten free, nut free and vegan.

Ingredients / INCI
How to use it
Morning and evening, on clean skin.
Thin layer, damp skin
A gel doesn't need piling on. Slightly damp skin gives the humectants something to hold onto.
Ten seconds and it's in
No film, no tack. Around the eye area too if you want, though never into the eye itself.
Cream over it if you're dry
On normal or oily skin this can be the last step. Dry skin wants something sealing it in.
Hydration without anything rich
Most products that hold water in do it with oil. This one does it with a film instead.

What's inside and why it's there
Nineteen ingredients, 99% of natural origin and 11% organic, certified COSMOS Natural by Ecocert. No oils, and nothing on the allergen list. Gluten free, nut free and vegan, GMO free, recyclable packaging.
Algin + Cellulose Gum
Algin comes from seaweed. Together with cellulose gum it lays down a fine, breathable film that slows water leaving the skin — the job an oil would normally do, done without one.
Sodium PCA
One of the things your skin makes for itself to hold water, placed unusually high here. Above the Aqua, in fact, along with organic aloe and glycerin.
Hyaluronic Acid + Plant Sugars
Hydrolysed fragments and the larger sodium hyaluronate, working at different depths, with rhamnose, glucose and glucuronic acid behind them. Organic sage and white tea finish the list.
Questions people ask before buying
Neither, quite. It's a gel that hydrates and then holds that water in with a film rather than with oil. On normal and oily skin it can be the last thing you apply; on dry skin it's a step, with a cream over the top.
None. Read all nineteen ingredients on this page — no oils, no butters, no silicones. That's unusual for something claiming to lock moisture in, and it's why the algin matters so much.
Yes, carefully. It's gentle enough for the area and light enough not to sit heavily there. Keep it out of the eye itself, and press rather than drag when you apply it.
Very well. Oily skin is often dehydrated at the same time, which is the problem this solves — water without anything rich added on top of the oil your skin already makes.
Yes, and it's a sensible thing to put underneath one. There's no acid, no retinoid and no vitamin C in it, so nothing competes — and hydrated skin copes far better with something stronger on top.
A substance extracted from seaweed, used here as a film former. It sets across the surface as the gel dries and slows the rate at which water evaporates out of your skin — the same result an oil gets, by a different route.
Nothing in this formula has to be declared as an allergen, which is rare enough in something fragranced to be worth saying. The scent is fresh and faintly fruity. Patch test anyway if your skin reacts to most things.
Yes — there's nothing in it that works differently depending on who's applying it. The texture is light and the scent is neutral, which tends to make it one people share.
Vegan, cruelty free, gluten free and nut free, with no GMO ingredients and recyclable packaging. Ecocert Greenlife certifies it to the COSMOS Natural standard, at 99% natural origin and 11% organic.
