The vermilion border (sometimes vermillion border) is the normally sharp demarcation between the lip (red colored) and the adjacent normal skin. It represents the change in the epidermis from highly keratinized external skin to less keratinized internal skin. It has no sebaceous glands, sweat glands, or hair.
---reasons for vermilion border being red--- there are three reasons-----1.the epithelium is thin,2.this epithelium contains eleidin which is transparent and the blood vessels are near the surface of the papillary layer,revealing the 'red blood cell' color.... at the angles of mouth sebaceous glands,without hair folicles.....are called fordyce's spotThe vermilion border is important in dentistry and oral pathology as a marker to detect disease, such as in actinic cheilitis.
[edit] Vermilionectomy
A vermilionectomy (or sometimes vermillionectomy with two Ls)[1] is the surgical removal of the vermilion border. It is sometimes performed to treat carcinoma of the lip.
