When my son goes out to play in sun, several times he end up with a white spot on face. I keep applying one skin ointment Gentelene Plus which reduces the problem but it comes back with exposure to sun. Please suggest

A. Hello ma’am I could be due to some allergy which is turning black with sun rays that means and these are reacting to it so I am going to advise you to please consult a doctor immediately for a check up and go for a course of medication to deal with it and do not self medicate because you know something that can worsen the situation also
