Pityriasis Alba is a common skin condition that primarily affects children and young adults. It appears as light-colored patches on the skin, often on the face, arms, and upper body. These patches are usually dry and may be slightly scaly, but they are not itchy or painful. The exact cause is not well understood, but it is thought to be related to sun exposure and skin dryness. The condition is generally harmless and often resolves on its own over time. Treatment is usually not necessary, but moisturizing creams can help improve the appearance of the skin. Pityriasis Alba is not contagious and does not indicate any underlying health issues.
