Ingredients
How to use
1. Unscrew the cap to open. 2. Transfer to the included dropper. 3. After toning your skin with lotion, take an appropriate amount and smooth it onto your skin. *Due to the nature of vitamin C, gas may be generated, so you may hear a gas escaping sound when you open the cap. *For safety, the container is filled with liquid, leaving some room for improvement. *Pure vitamin C is prone to discoloration, so store away from high temperatures and direct sunlight. *If not used daily, store in the refrigerator. *Always close the cap after use. *We recommend using within two months of opening.

Do you offer express shipping?
Yes. As of 22 July 2026, we offer International Express Mail through Japan Post. The cost is based on order weight and is calculated automatically at checkout.
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.
