A nice lip shape and a nice mouth will definitely add points to your facial features. Therefore, many girls have not ignored this point and have ideas about adjusting and improving their lips, such as making thin lips thicker, thick lips thinner, improving lip shape, etc. Beautiful lips can not only increase the overall beauty of the face, but also increase the sexiness index of women.
Introduction
The highest point of the lip arch on both sides is called the lip peak. The shallow groove running vertically from the columella to the edge of the lip vermilion in the middle of the upper lip is called the philtrum. The lip vermilion in the middle of the upper lip protrudes slightly forward and downward, forming a lip bead. The cleft of the mouth divides the lip into the upper lip and the lower lip. There is a slightly raised skin ridge on both sides, which is the philtrum. The upper and lower lips intersect at the corner of the mouth, and the free edge is the transition zone between the skin and the mucous membrane, which is called the lip red. The junction of the lip vermilion and the skin is called the vermilion edge. The vermilion edge of the upper lip is a graceful arch shape, called the lip bow. Western artists also call it the “Bow of Cupid”. ○ Thin lips generally refer to thin upper and lower lips, which become thinner when smiling. Thin lips make you look older and less friendly, and it is difficult for most people to control them. ○ Poor lip shape refers to the failure to achieve the so-called “ideal lip shape”. Front view: The ideal upper and lower lips will form three graceful contour lines at rest, similar to the letters M, M’ and w (or u). These three contour lines outline the five lip tubercles of the upper and lower lips. The position of the corner of the mouth is equivalent to the vertical line extending downward from the midpoint of the pupil when the eyes are looking straight ahead. When the lips are naturally relaxed, the maxillary incisors are exposed about 2mm, and the crown part can be exposed when smiling but not more than 2/3. The ideal upper and lower lip thickness ratio is 1:1.6 (or 1:1.5). Side view: The upper lip is slightly looser and thinner than the lower lip, lightly covering the lower lip, slightly raised and protruding; the edge of the lower lip should be close to the line between the tip of the nose and the chin. 
Lip anatomy
Various lip shapes
M-shaped lips is a broad concept, mainly including several characteristics: 1. Double M: The upper edge and lower edge of the upper lip are M-shaped, with an arc like a seagull spreading its wings. 2. There are “three beads”: there is one lip bead on the upper lip and two lip beads on the lower lip. There is a slight depression in the middle of the two lip beads. There is a protruding lip bead in the middle of the upper lip. There is a concept called “Korean three beads”, which refers to the three lip beads in the shape of the Chinese character “品”. 
What is an M-shaped lip?
Although M lips are almost universally recognized as a beautiful lip shape, there are also examples of other non-M lip shapes that are very popular.
The first is smiling lips, which means that the lips are moderately thick, the lip beads are full, the lip contours are clear, the lip peaks are sharp, and the corners of the mouth are slightly upturned even when not smiling. It makes people feel very friendly and contagious.
The second is the beaded lips. The biggest feature of this lip shape is that the lip bead is relatively prominent and can be seen from any angle. With this lip shape, the lower lips are not very thick and do not look aggressive, giving people a pitiful or pure feeling.
The third is thick lips. The characteristic of thick lips is that the upper and lower lips are relatively thick, which is a bit close to what we often call sausage lips, but it looks more beautiful than sausage lips. Although at first glance, the lips are more prominent in the facial proportions, and the facial features do not look very delicate and coordinated, it is precisely because of this that thick lips give people a very confident and full impression. Whether in daily life or among female stars in the entertainment industry, thick lips are very unique and distinctive. 
Affected population
The ideal lip shape should have clear lip contours, a size that is appropriate to the nose, eyes, and face shape, with obvious lip tubercles, full lips, rosy color, slightly upturned corners, and a three-dimensional feel. However, solving the problem of ugly lip shape and wrinkled lips with age is a difficult problem that all women need to overcome.
Treatment options
Hyaluronic acid filler
Introduction:
Hyaluronic acid, also known as uronic acid and hyaluronic acid, is one of the components of human dermis. In medical aesthetics, hyaluronic acid is injected as a filler into the dermis wrinkles, depressions or areas that need to be plumped up, such as lips, cheeks, nose bridge, chin, etc., to achieve the effect of removing wrinkles and filling the face naturally. Hyaluronic acid can be metabolized naturally and will not remain in the body, so there are no side effects. If you want to maintain it for a long time, you can inject it again.
Working principle:
By injecting hyaluronic acid, the volume of subcutaneous tissue is increased to support sunken lips, instantly achieving a natural shaping effect. It can also make fine adjustments to the lips to enhance the sense of refinement.

1. Face-to-face consultation: Determine the injection range and dosage based on personal situation and needs.
2. Preoperative preparation: Clean and disinfect the injection site. Make sure the medicine is brand new and unopened before injection.
