Hello doctor! I met with an accident on about 12 days back and got a deep cut on my cheek, there was also a glass piece which was removed after approximately 9 hours, a plastic surgeon gave internal dissolvable stitches and advised to use cold cream sunscreen and silicon gel thrice a day. Is that the best I can do for my skin because I read somewhere that it should be left to heal naturally. Which products should I use, I read about petroleum jelly and silicon pads is that the best?
