Is it possible for a burn scar to heal completely?

Ok the left side of my boyfriend's face was burnt and the skin looks pretty bad, he walks around covering his face, he has become ant-social, he hardly goes out and I want him to socialize with friends and go to football games and all that. he's afraid of looking for a job because he is uncomfortable and he thinks everyone is looking at him, I feel really bad, I love him so much, I was wondering if I could buy anything that will repair his skin, I heard of celltone, its made with snail jail but I want to hear your suggestions, I love him so much and it hurts me to see him suffer . I've not yet told him I want to do that
