What Is Pityriasis Rosea?
Pityriasis rosea is a mild skin rash with a pink, scaly and inflamed appearance. The condition is quite common, and it is not serious. It is most common in children and young adults but can occur at any age.
The rash usually lasts between 1 to 3 months and leaves no permanent marks. People with dark skin may notice lasting brown spots after the rash has healed.
Once it is gone, pityriasis rosea usually does not come back.
