I have heard great things about derma rolling to help re pigment skin is it safe to do on the penis? (Photo)

A year ago I received treatment for genital warts with TCA the treatment left me with a hypo pigmented scar. I have read about derma rolling and was curious if it is safe to try on the penis. If it is what length is recommended and would it do more damage or is it worth a try? Are there any other treatments that would help blend my skin back to normal? Or would simply tanning do the trick? I am a college student and have limited funds but constantly stress about this scar thanks in advance.
