Sir I had a fall and developed a very slight scrape in my face not even a little blood came. But it turned black and then scalp was formed. Once scalp went my doctor asked me me to use silver nitrate gel and I applied. The the scrpae turned to white slowly towards skin color. But all of a sudden it again started to turn black. I believe this was due to exposing to sunlight. Now my doctor gave novalate n cream to be applied with few drops of oil. It's been one month from my fall. I am worried will it cause black scar in my face. Is the cream which I am using is ok or should I use some other ointment to avoid the scar. Please help me.
