IMO there is no global answer to this,all of us heal and react differently to many different methods.The only way to heal well is to find out which method works best for each individual ,and the only way to find that answer IMO is through trial and error.There is no blanket rule/method that works for everyone.
in the many years that I have been getting tattooed,I have heard dozens of opinions,and methods seem to trend and change.
I think you'll find many people here advocate a dry heal. I've been dry healing for years - never bothered with creams and ointments. The body has an amazing ability to heal itself, so I try to leave it alone to heal. That's just me though. Each to their own.
