The cause of<unk>  is unclear. The use of topical steroids and cosmetics have the most important role. Although light exposure has been discounted as a causal factor, some reports of<unk>  have been made by some patients receiving Psoralen and ultraviolet A therapy. Corticosteroids<unk>  often happens after the use of topical steroids on the face, and is more likely to occur the greater the strength of topical steroid used. Discontinuing the steroids often initially worsens the dermatitis, and dependency on the steroids can occur as people believe the steroids were initially controlling the condition. Inhaled corticosteroids may also trigger<unk> .<unk>  has a tendency to occur on the drier parts of the face and can be aggravated by drying agents including topical benzoyl peroxide, tretinoin and lotions with an alcohol base. Immunosuppressants Reports of<unk>  in renal transplant recipients treated with oral corticosteroids and azathioprine have been documented. Cosmetics Cosmetics play an important role as causal factors for<unk> . Regular generous applications of moisturising creams cause persistent hydration of the layer causing impairment and occlusion of the barrier function, irritation of the hair follicle, and proliferation of skin flora. Combining this with night cream and foundation significantly increases risk of<unk>  13-fold. Micro-organisms Topical corticosteroids may lead to increase micro-organism density in the hair follicle. The role of infectious agents such as Candida species, Demodex folliculorum, and fusiform bacteria has not been confirmed. Psychosocial As a cosmetic impairment,<unk>  is increasingly documented to have psychosocial aspects to its cause and clinical findings. Specific personality structures, professions and social habits have been implicated in the type of person the condition occurs in. Other potential causes The condition may be potentially worsened by fluoridated toothpaste and inhaled corticosteroids. A high prevalence of atopy has been found in those with<unk> . The possibility of an association with the wearing of the veil in Arab women has been documented.
