INCI: Sodium Hyaluronate
Also known as: HA · Sodium Hyaluronate · Hyaluronic Acid · 히알루론 · Hydrolyzed Hyaluronic Acid
What it is
Hyaluronic acid is a humectant polysaccharide naturally present in skin. Cosmetic HA comes in multiple molecular weights — low-MW penetrates more, high-MW sits on the surface and creates a plumping film. K-beauty popularized the “multi-weight HA” narrative, layering several MW grades in one product for both surface plumping and deeper hydration.
한국어 설명
히알루론산은 피부에 자연 존재하는 다당류 보습제다. 화장품 HA는 다양한 분자량(MW)으로 나뉘는데, 저분자량은 깊이 침투하고 고분자량은 표면에 머물러 탱탱한 막을 만든다. K-뷰티가 대중화한 “다분자 HA” 컨셉은 여러 분자량을 한 제품에 레이어링해 표면 탱탱함 + 더 깊은 보습을 동시에 노린다.
