Hi am 24 years married girl. For past 2 months I got my pigmentation around my mouth. This has happened last year that time I was suggested by my dermatologist she gave me aziderm 20%, that time it vanished with in 10 days. But when now I started using it for past two months. It goes very slowly. This time when I saw another dermatologist she gave me lozee cream. I google it. But it had no connection with pigmentation. So am in doubt whether to use it or not. Currently I came across biluma cream. Whether I can use it or not without the knowledge of dermatology and currently am using vitamin c serum and aha serum alternative days.
