Pure ingredients that "don't need to be converted" and smoothly reach the stratum corneum. Supports the impression of skin with refined pores, transparency, and texture. [Formulated with NAD⁺] Foundation care with NAD⁺ (*2), a key ingredient that focuses on sirtuins. NAD⁺, a precursor to niacinamide, supports skin firmness and radiance, leading to a youthful impression from within. [Multi-faceted approach to pore concerns] Care from both the surface and the foundation. Vitamin C x NAD⁺ complement each other, enhancing the "realization" of pore care through formulation design. [Snap and Fresh] Prevents oxidation with single-use pouches and provides a fresh feel. Pouch type that seals in the ingredients. You can always use a fresh serum just opened. [Easy-to-use intensive care] Just add it to your daily skincare routine. Use after washing your face and before toner. Also ideal for intensive care on days when you are concerned about pores, dullness, and lack of firmness. [Co-developed with a cosmetic surgeon] Supervised by Dr. Rin Katsurada, Director of Tensei Clinic Osaka. A co-developed serum that "changes the common sense of pore care" born from a survey of 230,000 followers.
