AC is caused by chronic and excessive exposure to ultraviolet radiation in sunlight. Risk factors include: * Outdoor lifestyle: e.g. farmers, sailors, fishermen, windsurfers, mountaineers, golfers, etc. This has given rise to synonyms for this condition such as "sailor's lip" and "farmer's lip". The prevalence in agricultural workers in a semi-arid region of Brazil is reported to be 16.7%. * Light skin complexion: the condition typically affects individuals with lighter skin tones, particularly Caucasians living in tropical regions. In one report, 96% of persons with AC had phenotype II according to the Fitzpatrick scale. * Age: AC typically affects older individuals, and rarely those under the age of 45. * Gender: the condition affects males more commonly than females. Sometimes this ratio is reported as high as 10:1. Additional factors may also play a role, including tobacco use, lip irritation, poor oral hygiene, and ill-fitting dentures.
