What about Yingshu hyaluronic acid? How should it be used?

I think it has a very good hydrating effect, and there are many ways to use it. You can apply it directly on your face as an essence, or you can mix it with skin care products. I usually use it as a water mask. The specific method is to dissolve 1ml of hyaluronic acid in 15ml of purified water, then dip the mask paper into the mixture, and finally apply it to the face for 5-10 minutes. After using it for a period of time, I obviously feel that my skin is much more delicate and moisturized, and my acne has become less common. I feel comfortable even when I touch it, hehe~
