What it is
Contains three ingredients specifically designed for firming skin and pore care: (1) Trisodium Ascorbyl Palmitate Phosphate, a next-generation vitamin C that penetrates deeper than existing vitamin C. (2) Ascorbic Acid, a highly safe vitamin C. (3) Niacinamide. Niacinamide is synonymous with anti-aging care in Korea. It's a versatile ingredient that moisturizes, strengthens the skin barrier, has anti-inflammatory properties, and promises wrinkle improvement. *Age-appropriate care. All-in-one with five functions in one application: (1) Lotion (2) Serum (3) Emulsion (4) Cream (5) Pack. No need to rinse off. It's non-sticky, so you don't need to rinse off. A large, convenient 250ml bottle (approximately 2.5 months of daily use).

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.

We're working on rolling out prepaid duties for more countries soon.
