Cold weather may also trigger Raynaud's disease in some individuals, which causes blood vessels to constrict and spasm, slowing down circulation, according to Forbes. When the constricted blood vessels compromise oxygen, the skin warms, and fingers may turn a deep purple blue. The skin may also feel tingly, swollen and have a deep red appearance. In extreme cases, people with Raynaud's disease may need to carry an epinephrine pen to treat instances of anaphylactic shock.

Rosacea on the face, cheeks and nose may develop with exposure to cold weather, according to Forbes. With this condition, the face reddens and flushes, and spidery blood vessels may become visible on the face. In some cases, people develop pustules and bumps on the skin as well as a reddish, bulbous nose. Rosacea is typically treated with antibiotics, such as tetracycline, and patients are advised to avoid exposure to extreme weather conditions. When living in an area with cold temperatures, physicians recommend dressing in layers and protecting the face and head with hats and scarves to avoid skin exposure to cold weather.
