Hello,
Without examination,confirmation of a diagnosis is tough but it can be pityriasis versicolor or pityriasis alba. Pityriasis versicolor is caused by an overgrowth of a yeast fungus and are found mainly on sun exposed areas. Pityriasis alba is a common hypopigmented dermatitis. Pityriasis alba is a common skin condition mostly occurring in children and usually seen as dry, fine-scaled, pale patches on the face.

No treatment is required and the patches in time will settle in due course of time. The redness, scale and itch if present may be managed with simple emollients and sometimes hydrocortisone, a weak steroid, is also used.Severe cases may require PUVA therapy.

Hope it helps.Take care and pls do keep me posted on how your son is doing or if you have any additional doubts.Kind regards.
