Prophylactic warming of acral areas, achieved by heat and appropriate clothing, best prevents pernio.
Ultraviolet light, given at the beginning of the cold, damp season, has been touted as preventing outbreaks of pernio in prone individuals. Pathogenesis was loosely based on damaging the minute vessels and minimizing their ability to vasoconstrict with subsequent cold exposure. However, in at least one double-blind study, ultraviolet therapy was of no value in prophylaxis of pernio.
Avoidance of nicotine may help alleviate pernio.
Consult a dermatologist for diagnosis and evaluation of associated disease.
Thin body habitus may be associated with heightened cutaneous vasoreactivity; the healthcare provider needs to be aware of this population at risk and its possible need for nutritional intervention.
Prophylactic warming of acral areas with minimization of cold exposure may prevent disease recurrence.
