Hyaluronic acid, nano-hyaluronic acid and small molecular hyaluronic acid are different in molecular weight and function. Hyaluronic acid, a small molecule, can replenish water through the stratum corneum, which is more easily absorbed by the skin and has excellent moisturizing effect. Nano-hyaluronic acid has smaller molecular weight, which can penetrate deep into the bottom of skin to replenish water, with higher value and better effect. Traditional hyaluronic acid is mainly used for filling molding, and hyaluronic acid with different molecular weights has different uses.

In addition, the extraction process of nano hyaluronic acid is more complicated than that of small molecular hyaluronic acid, which also leads to their price difference. Therefore, when choosing to use hyaluronic acid products, you need to make comprehensive consideration according to your own needs and budget, and choose the products that suit you. At the same time, we should also pay attention to the selection of regular medical institutions and professional doctors for injection operation to ensure the effect and safety.
