In the case of thin lips, it is suggested that subjects can consider injection filling to make their lips fuller. At present, the injection fillers recommended by medical and aesthetic units generally include hyaluronic acid, collagen and autologous fat. Different fillers have different injection effects. It is necessary to analyze the individual's specific situation before finalizing the plan.

Hyaluronic acid naturally exists in our skin tissue, which will not cause rejection of human skin tissue after injection, but will be slowly metabolized and absorbed by human body after injection, and will not cause adverse effects on the body. At the same time, hyaluronic acid has strong water adhesion, which can make lips more moist and full, healthy and natural after injection.

Collagen itself is a kind of polymer protein, as a kind of skin protein, which accounts for one third of the total protein of our body skin. Lip augmentation can promote blood circulation, improve skin vitality and make lips rosy and beautiful.

Autologous fat is a small amount of fat particles extracted from the body fat accumulation area of beauty seekers, which is used to fill lips after special treatment. Because fat particles belong to the autologous tissue of beauty seekers, they will not induce human rejection. While filling the lips, you can also slightly adjust the curves of other parts of the body, killing two birds with one stone.
