Reliable guideline for children's health
Recently, I noticed that the skin around my child’s eyes was noticeably lighter than other areas. Although my child didn't experience any discomfort, I was still concerned and worried that it might be vitiligo. After a visit to the hospital, my initial suspicion was confirmed; the diagnosis was "pityriasis alba.”
Characteristics of Pityriasis Alba
Pityriasis alba typically presents as mildly depigmented patches on the skin with indistinct borders, often accompanied by fine, flaky scales, which is why it is referred to as pityriasis alba. It commonly affects children aged 3 to 16 years, primarily appearing on the cheeks and around the mouth, though it can sometimes be found on the neck, shoulders, and, in rare cases, the trunk and limbs.
Causes of Pityriasis Alba
Pityriasis alba is quite common among preschool and school-aged children, especially those with dry skin or darker skin tones. It can occur on its own or may be a manifestation of atopic dermatitis. Additionally, several factors contribute to the development of pityriasis alba:
Difference Between Pityriasis Alba and Vitiligo
Pityriasis alba and vitiligo are two distinctly different skin conditions. Vitiligo can appear anywhere on the body, with well-defined white patches that have smooth, scaleless surfaces. It generally doesn't cause itching or pain.
However, pityriasis alba can sometimes be mistaken for vitiligo, particularly in children. Parents are advised to monitor the condition, adjust the child’s diet, and maintain proper skin moisturization. If the symptoms don't improve after 2 to 3 months, or if the patches become whiter or spread, it's important to consult a dermatologist for a professional diagnosis.
Prevention and Care for Pityriasis Alba
Pityriasis alba usually doesn’t require medical treatment and often resolves on its own. To prevent it, parents can take the following measures:
After applying vitamin E cream for some time, along with proper sun protection and moisturization, and taking multivitamin supplements, my child’s pityriasis alba showed significant improvement.
