[General] Vampires seem to often have a natural charisma. How does this come about?

I heard it mentioned in the Monogatari series and I realized it's hard to think of a vampire (at least higher vampire) in fiction that doesn't have a high charisma level so to speak.

Is there a "magical" element to this, or is it purely them having nice skin from drinking blood?

Depends on the universe it's taking place in. If vampirism is caused by a virus, then it usually just makes you skinny and gives your face sharper features which is usually considered attractive. There's also some Darwinism to consider as vampires that are unattractive, despite having the virus, won't be as successful without going for the brute monster route.

If it's not so much a virus, but a curse, then it is indeed magical. Vampires are social predators that lure their prey into a false sense of comfort in order to more easily get them isolated so they can drink their blood or whatever. They're kinda like Djinni in that sense, as they promise to grant your every wish when they actually just suck out your life essence while giving you good dreams.
