What is the boundary of the vermilion?

The boundary of the vermilion is a line along the outer side of the lips, where they connect to the skin of the face. It can be a distinctive line, especially in Caucasians and people with light skin. The definition of vermilion is "brilliant scarlet or red". While the vermilion boundaries of the lips differ from man to person, it is not normally scarlet or red, but it can be a little darker than the rest of the lips. The red lip color is caused by the fact that in this particular area it is thinner than in the rest of the face and the area is well supplied with blood vessels.

Unlike the skin that surrounds them, lips, including the boundary of vermillion, have no sebaceous glands, sweat glands or hair follicles. This can explain why the lips tend to dry out, especially during the winter season, much easier than the rest of the face, although everything is exposed to exactly the same environmental factors. The sebaceous glands on the rest of the body exclude a pet, slightly waxance, which is assumed that it is involved in the prevention of skin dehydration.

There may be a number of diseases, the most famous herpes simplex, a highly contagious, recurrent disease commonly known as sores. Small blisters develop on the lip, usually along the outer edges that can slowly treat themselves or require topical or systemic treatment. Another condition that occurs at the outer edges of the lips is angular cheilitis. It is drying or hood in the outer corners of the mouth, which in severe cases can cause the lip distribution.

The

Vermilion boundary is involved in a number of cosmetic procedures. Lip tattoo is one. It is a process that includes lips tattoo to allow permanent deepening of their color. Some people decide to tattoo only on the edge of the vermilion, giving the effect of a permanent line insert. In some cases, people may tattoos around the outer edge of the vermillion border to expand their lips. All these procedures should dot only a trained professional and under sterile conditions.
