I think there should be a tiny, tiny chance (on all injury types) for the injury to cause a +1 to charisma. In addition to whatever other effect the injury has.

This would be for those rare but really cool scars.

Would you also lose it with a greater restoration potion?

Yes.

Charisma covers a lot of fields. A -1 or +1 does not necessarily involve an ugly or intimidating scar. A negative CHA injury can as well mean a drop in self confidence or a person turning more inward, being cynical and less relying on others. How that works for the plus side is open to interpretation. Just saying there are a lot of options when it comes to roleplaying CHA.

Not only that, but "injury" is open to interpretation in DnD as well. Losing hitpoints does not always means being hit/struck. It can mean a loss of stamina or vigor. Or being "lucky" and avoiding actual injury, by a grazing blow, and losing hitpoints is luck running out.

And then there are people who wear fullplate and helmets, how would they get scars when struck with a slashing weapon? And bludgeoning weapons, or other weapon types may not even leave scars, they would break bones etc.

Charisma is a mental stat, it is very similar to wisdom and intelligence in ways. It iss more logical to lose physical stats when suffering injuries but... how does one suffer an injury and how is that defined in DnD? The system is not build around losing stats easily, just under drastic/special circumstances. In most cases this is temporary with the rare exception of it being permament (And in those cases the resotration spells can help fix it, so "permanent" more in the sense of it not going away on its own)

Funny suggestion, but it would not be very fair towards characters that have another attribute as their main stat.
It would also reduce the impact of losing a stat point in Charisma, which is already minimal for a lot of characters.

Perhaps it would be more fair and accurate as a rare chance to gain +1 to the Intimidate or Bluff skill instead?

That would fall in the same category as what I mentioned above. Where would this +1 intimidate/bluff come from? Why would they get better at it? Scars is a relative thing.

Aside from that, these are social skills, based on charisma/social know-how, not appearance. A scar can look intimidating, sure. But it can also take the bark out of someone, or make them look a worse warrior ("Why else would they get so scarred?").

The DnD system is not really build around this, this would be trtying to re-invent the wheel in my opinion. I think scars and how injuries are taken should be left to interpretation and based on the character and how they RP it, that way there will be a lot more creative RP than being forced into a corner/box with it. If people feel any scars they may give their characters would make them more intimidating, that is what skillpoints as for, really.

It may still be a bad idea, just trying to be constructive. This feature would probably not add anything to the server or RP.
In the end you don't really need a stat bonus to RP out being scarred, whether it is a badass scar or a hideous burn mark.
