Here in Northern Italy almost everyone uses Bepanthenol, which is a cream made up by 5% Panthenol ( https://en.wikipedia.org/wiki/Panthenol )
I don't know, I've been lurking on forums and such for years but I think I very rarely read about Panthenol.. to me, it's the perfect one! Of course we are all different, I use it for exactly 14 days regardless on the spot, colors or size.. has always worked perfectly!
I read the article above on inkluded.co.uk, which actually refers to the UK market (the Bepanthenol product sold in Italy is made in Italy and probably is different, it contains only 5% Panthenol).. I really don't know what to say, my tattoo artists use that cream, I have always been using it and my tattoos are all perfect, even those 10 or 12 years old but I'm not a doctor so I can say anything more..
For soap, I have always been using Neutro Robert's antibacterial soap, sold in every supermarket. It's a brand from Florence and I learned right now this thing, I thought it was English ahah but ok, we have Dove soaps everywhere too..
