Hydrogel mask with 70% heartleaf water (Houttuynia cordata) and soluble collagen that soothes sensitive skin and provides long-lasting hydration. The formula contains 70% heartleaf water along with aloe vera extract, hyaluronic acid, and low-molecular soluble collagen (60 ppm), which helps achieve a smoother, more supple complexion. The hydrogel texture conforms well to the face, while the essence gradually absorbs for a pleasant, refreshing feel. Particularly suitable for sensitive, dehydrated, or irritated skin needing calming and balancing. The mask offers a cooling effect and is also ideal for overnight use. The color-changing film (approx. 1 mm) transitions from light green to transparent as the active ingredients are absorbed, indicating the essence has been fully taken in. Stays securely on the face without leaving any sticky residue.
