Pityriasis Alba is one type of skin condition which affects mostly children and adolescents. Its cause remains unknown, but is commonly found in those with dry skin and atopic dermatitis.
Pityriasis, as defined, is type of skin disease associated with shedding of fine flaky scales; while alba means ‘white’ in Latin. Pityriasis alba is hence presented in the appearance of white/pale-coloured spots on the skin, with fine scales. Affected areas normally include cheeks, neck, shoulders and arms, while other areas are rare. The spots might be scaly, with round/oval or uneven shape and edges. The person might feel minimal itch or no itch at all.
The spots would normally go off with time, even without treatment. However, for those concerned parents, treatment using moisturizing cream, topical steroid cream or cream containing immunomodulators such as tacrolimus might be considered to hasten recovery of the skin colour or to reduce the itching.
Here are a few tips to those affected with pityriasis alba.
First, avoid exposure to sunlight and always apply sunblock. Secondly, practice good skincare and hygiene. And lastly, avoid over cleansing of face as it will cause dryness of the skin. Practicing the points mentioned above would not eradicate incidence of pityriasis alba totally, but it will reduce the recurrence of it. Nevertheless, please consult your physician if you have any doubt.
