Nose Discolouration and Spots Refuse to Go Even After 3 Years?

I'm a man. 3 years ago I went for a facial massage and this trainee by mistake used some chemical and a machine on my face that left one bad scar on my cheek and discoloration and brown spots all over my nose. Using creams I have been able to treat my cheek scar 60 % but my nose problem remains as it is. Today I bought a Mederma Advncd gel for both my cheek and nose and I hope it helps. In case it does not, what cream should I use for my nose problem ? I want my spotless original nose skin back.
