Hyaluronic acid is also known as hyaluronic acid. Hyaluronic acid has very good water absorption and has a very strong moisturizing function. It can be said to be the strongest moisturizing factor in maintenance ingredients. One molecule of hyaluronic acid can absorb about 1000 times of water. The moisturizing effect of the original acid solution and the sleeping mask is not to be mentioned!
Method: After cleansing, pat with toner until semi-absorbed, drop 2-3 drops of hyaluronic acid solution on the face evenly, and finally put on the sleeping mask. It is recommended to use 2-3 times a week.
