Lip Care
1.3 Varies with device
One of the most frequent changes of the lips is a blue coloring due to cyanosis; the blood contains less oxygen, and thus has a dark red to blue color, which shows through the thin skin. Cyanosis is the reason why corpses sometimes have blue lips. In cold weather cyanosis can appear, so especially in the winter, blue lips may not be an uncommon sight.
Inflammation of the lips is termed cheilitis. This can be in several forms such as chapped lips (dry, peeling lips), angular cheilitis (inflammation of the corners of the mouth), herpes labialis (cold sore, a form of herpes simplex) and actinic cheilitis (chronically sun damaged lips).
Cleft lip
Carcinoma (a malignant cancer that arises from epithelial cells) at the lips, is caused predominantly by using tobacco and overexposure of sunlight. Alcohol appears to increase the carcinoma risk associated with tobacco use. It is most often a diffuse and often hyperkeratinised lesion, occasionally has the form of nodules and grows infiltratively, and can also be a combination of the two types. It more often occurs at the lower lip, where it is also much more malign. The lower lip carcinoma is exclusively planocellular carcinoma, whereas at the upper lip, it can also be basocellular carcinoma
