Radiofrequency Treatment is Safe?

I had many pimples on my nose when I was 17. They eventually cleared up but they left many skin coloured bumps. Now I am 21 yr old female and they still r present on my nose . I spoke to my dermatologist and he suggested one session of radiofrequency injections for them and later I would have to over it with a plastic coating for day and they would leave pigmentation which could be reduced by using creams.Is this treatment is safe? Are there any side effects? What other treatment would you suggest?
