I used biluma cream morning, trauma cream evening and oberlite cream at night as per the doctor recommendation. Doc said only 2 month course. After that I couldn't able to go to doctor because of good result I continued around 4 months. Now I went to doctor for consultation. Now he said to me to stop everything. Just continue sunscreen. My doubt is if suddenly stop everything causes any pigmentation. I am afraid my face become black or what. So shall I continue oberlite and biluma cream to maintain my face color. Oberlite and biluma causes any problem if I apply long term. Please answer me. How to maintain without any side affects.
