How to draw lips, learn

Lips are one of the most distinctive facial features of the human body, and are a part of the body that everyone who studies painting must master. However, different people have different mouth shapes, and the painting methods are also different. I believe that many beginners in painting find this very distressing. Next, let’s learn how to draw beautiful lips.

Mouth structure:

The mouth is attached to a semi-cylinder formed by the upper and lower jaws and teeth, and its shape is arc-shaped. The mouth is composed of upper and lower lips, mouth line, philtrum and chin-labial groove. The upper and lower lips are two opposite W-shapes. The upper lip is longer, with a distinct lip line that protrudes from the lower lip. There is an upper lip tubercle lip line in the center that divides the upper lip into two.

The philtrum is located above the tuberosity line of the upper lip and is the groove between the nose and mouth. The structure of this part changes from concave to convex, making its contrast change more prominent. The changes in the lower lip are relatively smooth, with two tiny protrusions formed by the left and right lip tubercles. The chin-lip groove is located in the lower center of the lower lip. It is the arc-shaped turning line formed by the protruding bottom of the lip and the front of the chin bone. The dark part of this part is the reason why the lips are lifted.

The mouth line is a wavy line formed when the upper and lower lips are closed, with the two ends being the corners of the mouth where the lips terminate. The changes in the mouth line are very complex, consisting of several factors such as the lip gap, the projection formed by the upper lip, and the structural turning point. The expression muscles of the mouth are very developed. They make the mouth lines and corners of the mouth produce rich changes, and are the main part of depicting character expressions.

Perspective changes of the mouth:

Studying the perspective changes of the mouth at different angles requires a long period of research and contemplation, and with the help of sketching techniques, we can draw the mouth very accurately.

Finally, when we practice drawing the mouth, we should pay attention to the relationship between the mouth and the surrounding muscles. The expression of the mouth will cause changes in the facial expression. When drawing the lips, because the lips are red, beginners often paint the lips too dark or too dark to show the red feeling. In fact, this is not harmonious in the picture.
