What it is
This pre-face-wash serum is packed with everything you need for fresh, clean skin after cleansing. Based on fermented Galactomyces ferment filtrate, it contains Hydroveil, which creates a pathway for moisture, and Repair Booster, which thoroughly treats dryness. It also contains natural extracts for clarity and firmness. The bouncy droplets dissolve smoothly on the skin, creating a pathway for moisture while delivering beauty ingredients. Its 6-free formula contains no unnecessary ingredients for the skin. It has been carefully crafted to strike the perfect balance between freshness and a moisturizing film, making it suitable for use in any season, on any skin type, or with any skincare combination.

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.
