Facial capillaries can be damaged by cold weather, dryness, aging and certain medical conditions, according to Dr. Bailey, dermatologist. Once these capillaries have been damaged, they show up as blotchy red spots on the skin.
Diode laser treatment can remove the spots caused by damaged facial capillaries, but steps can be taken to minimize or prevent the damage from occurring in the first place. Protecting the face from sudden and extreme temperature changes and letting the skin adjust to those changes gradually can help to prevent damage. Preventing facial skin from picking up germs from hands and fingers can be aided by frequent hand washing. Using sunscreen and moisturizers and limiting the consumption of caffeine and alcohol will also help to prevent damage to facial capillaries.
