“About ten days in. It feels hydrating and nourishing, and it's thick with plenty in the bottle so I use it liberally. My skin is moisturised and glowing. I don't reach for other ampoules any more. Do try it — it's the kind of ampoule you want to keep to yourself ^^ I'll order again when it runs out.”

Several forms of hyaluronic acid layer lightweight moisture across the skin's surface, so skin looks plump and smooth rather than weighed down.
A marine ferment used in Korean formulas for a conditioned, refreshed-looking finish.
A familiar pairing that supports a bright, comfortable, well-moisturised look.
Leaves skin looking refreshed and awake — especially nice as a morning step.

I first bought it as a set at CHICOR while out shopping with a friend, then ran out of this one and repurchased. The weather has turned cold and my face feels desperately tight — I don't think anything else compares. I keep recommending it to my friends. Please keep making good products.
