Fairytale-esque book with female protagonist who loses her memory and is disfigured

I read it about ten years ago, I think it’s a trilogy.

The girl has no memory but is also disfigured from falling into some thorns or something? She’s healed at some point- I think when some fae prince kisses her.

There’s lots of creatures throughout, with an Irish folklore type feel to them. I think some of the story takes place in mans world and some in a realm.

That’s pretty much all I can remember…
