Ingredients
Water, 1,2-hexanediol, hydrolyzed hyaluronic acid
How to use
Immediately after washing your face, apply directly to the entire face. It will penetrate smoothly into the skin, leaving it moisturized.

Will I pay customs or import fees?
US orders: No. As of July 1, 2026, all US orders ship DDP (duties delivered prepaid), meaning we prepay all import duties on our end. Nothing is due at your door.
Orders outside the US: Possibly. Duties and import taxes are set by your local customs authority and are not collected at checkout, so any charges on delivery are your responsibility.
We're working on rolling out prepaid duties for more countries soon.
It is relatively moist.
I always thought of hyaluronic acid concentrate as something thick, but this one felt like a light lotion, so I wondered if I'd made a mistake and if it would even work, but it absorbed very well into my skin and left it moisturized. My makeup went on well the next morning, so I'll continue using it for a while. It's also fragrance-free, which is great for sensitive skin.
I used about half of it, but I didn't really see any visible results, probably because I was using other products. I think it would be good to continue using it. I mixed it with serum or cream.
