Aww, I understand your concern! May kaibigan ko din na nag-worry about this sa anak niya, sometimes it's just a harmless skin condition like tinea versicolor or pityriasis alba na common sa kids, lalo na kapag humid ang weather, pero honestly best na i-check ng doctor agad para ma-rule out and ma-confirm kung ano talaga yan at what treatment ang kailangan. Kung excited ka ma-address agad habang nag-aantay ng appointment, make sure the area is always clean and dry lang muna!
