2 weeks back when i woke in the morning, i found a reddish area on my cheek. it was burning in the sun. i consulted a doctor and was told that it s due to a acid bug. he prescribed me with fusidic acid with steroids. It got healed with all scab fallen. Now there is a pale line. how many days will it take for the skin to look normal? Please advice me for any measures to heal it faster.
