神經醯胺3B型(Ceramide IIIB):促進肌膚天然保護層的更新,形成一層有效的屏障因 而可抑制水份流失。此分子釘特別適合修護敏感性與乾性肌膚。
One of the many types of ceramides that can be found naturally in the upper layer of the skin. Ceramides make up about 50% of the goopy stuff that's between our skin cells and play a super important role in having a healthy skin barrier and keeping the skin hydrated. It works even better when combined with its pal, Ceramide 1.
