Emyu Beaute Moisture Rich Cream 50g Used only twice. The outer box has traces of tape removal and some writing. Please comment if you don't need the box. The main ingredient of this beauty cream is "proteoglycan." This was once a rare ingredient, so difficult to extract that a pinch of it cost 30 million yen. It has the ability to hold water like a sponge, and its water retention capacity surpasses that of hyaluronic acid. Since it is originally a component found in the body, it is also absorbed smoothly. It is said to also support collagen and hyaluronic acid. Purchased in early December 2025 and opened about a week and a half ago. Thank you. Product number 1.557
