Unhealthy skin on shaft linked with hpv and laser

hi, so since february i was takin condyline on hpv warts, after 5 weeks it destroyed my skin so much i went to dermatolog and he deleted in 3 weeks all of them. now i dont have new but the skin is really darker in some places, that is normal? please help me with opinion because i spent tousends in private clinics already and since february i have only this on mind. i take gel called zinofalt that derm said to take . shall i go directly to estetic clinic?
