Strawberry marks are made by kissing. The formation principle is similar to cupping. Use your upper and lower teeth to gently bite a small piece of skin, inhale deeply, and suck the other person's flesh into your mouth like eating jelly. Depending on the intensity, the color of the hickey will range from pink to dark purple. This leaves a hickey on the neck, which is the technique for growing strawberries.

Generally, the common places to plant strawberries are on the chest, neck, shoulders, back, and the face and forehead. However, it is best not to plant strawberries in this way, which will affect the appearance.

The reason why strawberry prints appear:

It is mainly because the pressure outside the human body has decreased, but the pressure inside the human body remains the same as before. At this time, the blood in the capillaries It will flow outward from the capillaries, forming some small blood clots similar to congestion on the surface of the human skin. Generally, kissing does not produce hickeys. Hickeys are subcutaneous congestion.

Hickeys are produced for two reasons; 1. They are caused by the mechanical behavior of teeth; 2. They are caused by the negative pressure of suction. The reason for the formation of hickeys is that when kissing too hard, the skin becomes congested, especially in areas with very delicate skin like the neck. It is easy to form hickeys due to hard kissing. However, don't worry, it will recover automatically after a few days. .
