Stefan,
Saponificio Varesino gave me a mild burn, but that's not why I stopped using it. The fragrances were intoxicating, but I found the soap had weak cushion. I still have a new puck left somewhere in my soap and cream cabinet.
I have not used Pannacrema Nuavia. This is an expensive soap, loaded with fragrances, and I fear spending the money and having my face fried — I read in several places of people experience burns with the soap.
A heavy beard and ultra sensitive skin, that's me.
