I've seen the same claimed for various celebrities also, including Nicholas Cage for that matter.
Same can be said about Gioconda transitioning fx montages via software.
I realise this is a topic in jest more than anything, but anyway, we have pictures of Putin from a young age, and the hypothesis of his timetravel would also entail "God stopping or slowing down his ageing process", since he looks young for his age already. If he were to have spent considerable time in the past (years) he would be much older than his reported age.
