What is the most frightening face Voldemort was described having? (in the book Half - Blood Prince)

I personally think it's the one from Dumbledore's memory, when he asks him for a job. The soon - to - be Voldemort J.K. described was so frightening. I mean, آپ have there a human being, who no longer looks human. The eyes are already then temporarily bloody, his skin looks like wax, and he's no longer the beautiful Tom Riddle, but now on of the darkest wizards rising...Wasn't that scary? I mean, sure, he was scary with his wax - like face and red eyes after the transformation was over, but I knew he wasn't human, I knew there was no way back for him then...And to be honest, he was hot when he was a teenager!! As a kid...well, he was just a kid. Dunno, wasn't frightening at all...
