Principle: Take out the fat in the eye bags with a needle, which has the advantage of low price. Disadvantages: Because the size and position of each person's eye bags are different, the depth of the doctor's insertion into the hour tube is not easy to grasp, and the fat in the eye bags can't be cleaned, which is very easy to hurt the eyes. Moreover, a large number of anesthetics must be injected, and the surgical site is obviously swollen and the recovery is slow, which can only last for about half a year.

2. Principle: Using a scalpel to cut the skin and orbicularis oculi muscle where the eye bags are located to remove fat has the advantage of low price. Disadvantages: Because there are too many capillaries in the eye, a lot of bleeding during the operation will inevitably block the doctor's sight, and the amount of skin removed is not easy to master, which is easy to form eyelid ectropion. It may leave scars, the fat in the deep bags under the eyes can not be completely removed, and it is easy to recur, and the swelling of the operation department is obviously easy to recur.

3. Laser method

Principle: Burn off the fat under the eyes with a laser. The advantage is no bleeding. Disadvantages: strong light stimulates eye surgery, which requires opening a small hole in the eye first and then cauterizing it with laser. The pain obviously has a strong burning smell, and anesthetic must be used. Because the laser can't bend, it can only burn the surface, not the root, so it can only change the big bag into a small bag, which is easy to recur.

4. Radiofrequency ablation

Principle: Using radio frequency ablation instrument, the orbital septum fat in eye bags will be melted and removed evenly at one time, which will make you feel hot and bloated. Its advantages are no bleeding and cleaner than laser method.
