Definition: Rosacea is a dermatological condition that only affects the face - usually the sides of the nose, cheeks, forehead and chin. It tends to come hand in hand with spotty outbreaks. Rosacea affects more women than men, with fair or sensitive-skinned people getting the worst deal. It's a visible condition that can affect us psychologically - the fact that it's often linked to alcoholism plus our desire to have a clear complexion can harm our self-confidence. Causes: Genetic or environmental factors (UV rays, changes in temperature), lifestyle (spicy food, too much booze), circulation problems, parasites... The causes are many and your best bet is to see a dermatologist. Prevention: First of all you'll need to weed out the triggers to figure out the best treatment plan and then do your best to avoid them like the plague. Avoid exposing yourself to the sun, cut out any drinks or foods that dilate veins, avoid extreme temperatures, saunas and long, hot baths (sorry!). Treatment: Treat any spots with topical anti-inflammatories or, if necessary, antibiotics. As rosacea comes in bouts, you may need renew any treatments. Laser treatments can be used to banish spider veins and red patches. If your visible veins are too much to bear, you can try electrocoagulation. Using a needle, a dermatologist will apply an electrical current to affected veins. It works a treat, but be warned that it's a painful process!
