Shingles typically causes a painful rash with blisters that may itch or tingle, which appears on one half of your body and scabs over in 7 to 10 days. The scabs usually clear up within 2 to 4 weeks of the infection, but permanent scarring or skin discoloration can occur.

In about half of shingles cases, the condition may cause permanent scarring at the site of the original rash, as well as skin discoloration due to a loss of pigment.

More severe or widely spread infections are more likely to cause scarring. According to a small 2023 study, other risk factors for scarring include:

  • age above 60
  • severe skin injury combines with diabetes
  • suppressed immune system
  • history of scarring
  • picking at the rash

The scarring is usually mild and consists of lighter mark on the skin. Raised scarring may rarely occur.

The most important thing you can do is to see a healthcare professional as soon as you notice the symptoms of shingles. The American Academy of Dermatology recommends visiting a healthcare professional within 3 days of symptom onset for effective treatment and to prevent longer-lasting complications

Avoid touching your rash and wash your hands often. Once your shingles rash begins to scab over, avoid touching or picking at it, as this can increase the chance of scarring.

A doctor can recommend over-the-counter and prescription medication to deal with itching, pain, and discomfort that you experience.

Once the scabs have fallen off—but not before—you can use fragrance-free moisturizer on the affected skin, which may help prevent scarring. Keep the affected area out of the sun to help prevent discoloration.

It’s possible for shingles to cause permanent scarring and skin discoloration, though this is often minor. If you develop shingles, it’s important to visit a doctor for diagnosis and treatment as soon as possible. Timely treatment can limit the discomfort and pain you experience and may prevent longer-lasting complications like scarring.

If you have not had shingles and are 50 and older, or 18 and older with a weakened immune system, the Centers for Disease Control recommend you get vaccinated against the virus.
