Medical Care

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. [15]

Avoidance of nicotine may help alleviate pernio. [4]
