Suggest Remedy For White Spots On Face

Hi,sir. My name is Ravi Teja,18 yrs old. I got some white spots spreading over my face. Dermatologist recommended me diprovate RD and advised me not to stay in sunlight. Some parts of face spots faded much and some a little. I used this cream for about 2 months. Now the dermatologist has changed the cream. I applied it but it resulted in serious spreading over my face again with severe itch after washing face.iam very much worried about it.Any help would very much appreciated. Thanking you.
