Will Hanna age faster now?

So Hanna is actually 200 years old but this eel serum has been making her age very slowly so she's only a teenager now. The sanitorium burns down and her mad scientist father is killed so there can not be any more youth serum produced. Now that she stops taking the serum, will she start aging at a normal rate or will all her age catch up with her and she'd age very quickly?
