What Penny actually has is a piece of Pietro's soul, not just his Aura. I don't know why, but for some strange reason, the writers decided to refer to both the soul and the energy that comes from the soul as Aura, which just makes things hella confusing.

So when the characters say that Pietro gave part of his Aura to Penny, they're actually saying he gave part of his soul to Penny. That's why it has had such a damaging effect on him. Aura (the actual energy) regenerates, so if it was literally just Aura itself, he would be fine. However, he's ripping pieces off his soul, and the soul itself does not regenerate.
