Hyaluronic acid can be replenished by injection. After injection, the skin will be tender and moist, rebuild the water-fat protective film, and make the skin healthy and shiny. After injecting hyaluronic acid, it is still necessary to strengthen moisturizing and let water be absorbed by hyaluronic acid. It's best to make more hydrating masks and rub more thermal cream to make the skin reach the best state of lasting hydration. The effect of injecting hyaluronic acid as a deep hydrating and skin care for the face is worthy of recognition. Friends might as well have a try.
