저자극 Sodium PCA is well tolerated by all skin types, including sensitive and dry skin. It is non-irritating, non-comedogenic, and safe for long-term use. Because it complements the skin’s natural moisturizing factor, it offers balanced hydration without adverse effects

강력한 수분 보유(표피에 보습막 형성), 각질층 천연보습인자(NMF), 피부탄력·윤기 부여, 자극 최소화 Sodium PCA is a naturally occurring component of the skin's natural moisturizing factor (NMF), derived from the amino acid proline. It binds water molecules from the environment and deeper skin layers, creating a reservoir of moisture in the skin’s outer layer (stratum corneum). This helps reduce transepidermal water loss (TEWL), keeps the skin plump, smooth, and elastic, and supports the skin barrier function. Sodium PCA also exhibits anti-inflammatory properties and helps reduce skin irritation. Regular use improves skin texture, resilience, and may relieve conditions like eczema. (추천 피부타입: 모든피부타입)
