Some people think cherry mouth looks good, while others think plump red lips are more attractive. So, what kind of lip shape is the best? The beauty of lips lies in the shape of lips. The structure of lips is divided into upper and lower lips and cleft lip between upper and lower lips, and the shape of lips is closely related to the thickness, width and size of each part. The perfect lip shape should be moderate in size, symmetrical in width and moderate in thickness. First, from the size. Cherry small mouth is generally the representative of beauty, so how small is it? In fact, it must also match the face. The general standard can be based on the vertical line of the pupil when the eyes look up, which is too wide and too narrow. Only if the mouth crack is of moderate size is the most beautiful. Second, from the thickness. The importance of lip thickness to lip shape can not be ignored. If the lips are too thick, the operation of thinning the thick lips can achieve the ideal effect, and the scars are not easily exposed to the inside of the mouth. If the lips are too thin, you can also perform lip thinning surgery, usually injecting autologous fat or collagen to increase the thickness of the lips. Third, from the appearance. Lips are often described as shapeless. Careful analysis of the shape of this lip shows that there is an arcuate line under the upper lip, which is called "lip bead" in medicine, and it is an extremely sexy point of the lip. Many beauty lovers specialize in lip bead plastic surgery to increase their charm index, and the postoperative effect is good. It is not difficult to see that the beauty and ugliness of the lip shape are determined by many factors such as the size, thickness and shape of the lip, and the lip shape is not beautiful enough. We can achieve the purpose of lip beauty by painting thick makeup, injecting lip augmentation and surgical correction.
