While working in the lab, a few drops of concentrated sulphuric felt on my arms. I washed it off almost immediately with water and also applied sodium bicarbonate paste on it to neutralize the acid. After about an hour, I applied Burnheal cream (Silver nitrate and chlorhexidine gluconate cream). The acid has left reddish brown marks on my skin after a few hours. Please tell me what can I do next to minimize scar formation. Thank you.
