Has there been much talk about rejuvenation treatments in previous stories? (I've got a huge gap in my JD collection between 2002-2014 so I'm not sure if it's a newish concept for MC1).
I think Dredd previously had a 'rejuv' after Necropolis. It was kind of mentioned in passing as an explanation of why his face wasn't all scarred anymore but nothing specific about it was seen.
I realise this interests nobody
else, but the treatment to which Dredd submitted following Necropolis 
was a cosmetic procedure, intended to repair damage
rather than restore youth
The machine is clearly labelled DERMAGRAF, as in skin graft, and the technician makes it clear he's repairing damage for cosmetic
reasons. An Ennis character later referred to this as a rejuve 
, but Ennis's entire stint on Dredd can be summed up as misunderstanding what Wagner had written and getting it just slightly
wrong when he tried it himself.
I'm not sure rejuve
means what we assume it does. It might only be a cosmetic procedure - why else would people pay so much for Stookie, which restores youthful vigour
as well as looks - and only temporarily
, at that?
I would have preferred that Dredd kept the scars from his brush with the Sisters. I'd gotten used to him walking around looking like a pepperami, and that felt like it was in keeping with the way stuff that happened to 2000ad characters was permanent and had repercussions.
