(1) Although the effect seems to be similar, their surgical positions are completely different in terms of surgical principles and procedures.

(2) The key position of the smiling lip is to raise the corners of the mouth, mainly in the corners of the lower lip, so as to keep the smiling effect after operation;

(3) DuDu lips start from the lips, which makes the lips, especially lip bead, more prominent, and the lips look full, moist and sexy.

2, different ways of action.

(1) Smiling lips mainly make an incision in the corners of the mouth, and pull up the corners of the mouth through surgery to correct the drooping corners of the mouth or keep the corners of the mouth in a natural state. After all, drooping corners of the mouth will make the whole person look depressed, such as Huanbi in Zhen Xuan's biography and actress Zhang Ting.

(2) DuDu lip is a method of lip augmentation by injection of hyaluronic acid, which belongs to a kind of lip augmentation operation by injection. Hand-shaped after injection molding, so that the lips are full and stylish, and the lip bead lip line is obviously three-dimensional. The specific effect can be seen in Korean dramas. Most female hosts look pouty, cute and sweet with a little awkwardness.

3. The maintenance time is different.

(1) Smiling lips were surgically lifted at both corners of the mouth. One-off surgery can achieve very lasting results. Generally choose a regular plastic surgery hospital, and there are basically no side effects.

(2) Hyaluronic acid was injected into DuDu lip, which was absorbed in the middle, so it didn't last long. If it is as short as 6 months, it will need to be injected again in 2 years, and the lips will collapse prematurely because they are absorbed too quickly. This is also the reason why actresses photographed by the media are suspected of frequent cosmetic surgery, which has a lot to do with the absorption of hyaluronic acid.

4. The effect presented is different.

(1) Smiling lips have an upward lip angle and an M-shaped lip shape. Because the middle of the lips is not moving, neither thin nor thick, so just smiling lips can only make the whole person look smiling all the time, but can't change the temperament of the whole person.

(2) DuDu lips are full, which will look sexy and have some petite and lovely feelings.

5, the suitable lip shape is different

(1) smiling lips are generally not suitable for plastic surgery for people with big mouths, which will make their mouths bigger. Please refer to the baby's for details. When you laugh, your mouth will look big.

(2) Doodle lips are not suitable for thick lips. After all, thick lips are already very thick, and if you inject lip augmentation, it is estimated that it will become a sausage mouth. The ratio of the upper lip to the lower lip of DuDu lip is preferably 1: 1.2, which looks better.
