What is white roll of lip?

White roll of lip, also known as vermillion border, is the border between the skin of the face and the vermilion zone (the reddish portion) of the lips. It is a well-defined border that helps to give shape and definition to the lips. The white roll of lip is more prominent in some people than it is in others, and it can vary in size and shape from person to person.

The white roll of lip contains specialized cells that produce a substance called keratin, which helps to provide a protective barrier for the lips. This gives the white roll of lip a slightly rougher texture than the smooth surface of the lips themselves.

There are a number of cosmetic treatments available that can enhance the appearance of the white roll of lip, including dermal fillers, lip augmentation, and lip lifts. Some people choose to have these procedures done to give their lips a fuller, more defined look.

Overall, the white roll of lip plays an important role in the aesthetics of the lips, and is an important factor in many cosmetic procedures aimed at improving the appearance of the mouth area.
