Davie, FL dermatologist Marianna Blyumin-Karasik, MD says it’s estimated that 50 to 90 percent of people have been exposed to the herpes simplex virus (HSV), which can lead to the common viral skin infection of cold sores. About 30 percent of people will develop recurring visible symptoms. Most of the symptoms manifest around the mouth as painful sores that can scab and occasionally scar, says Dr. Blyumin-Karasik.
Not only are cold sores uncomfortable to deal with in the moment, but Dr. Blumyin-Karasik says the condition can also “lead to disfigurement and impact psychosocial wellbeing and quality of life.” HSV lays dormant in nerve endings and can reappear periodically, causing these symptoms to pop up, says Campbell, CA dermatologist Amelia K. Hausauer, MD.
Cold sores may seem impossible to prevent, but experts have some advice. They can be triggered by a host of factors, including “compromised immune status, hormonal fluctuations, exposures of the body to drastic temperature changes and ultraviolet radiation,” says Dr. Blyumin-Karasik. However, experts say there are a handful of things you can do to alleviate and prevent cold sores. For starters, Dr. Bluyimin-Karasik says it’s important to get regular sleep, reduce stress and keep your immune system strong.
