Fable 2 - Becoming Young Again

There are a lot of way you will find on different websites to get young again in Fable 2, however these are the results I've had.

When you complete the main storyline your scars will be removed.
To actually look young again, you can purchase Brightwood Tower (around 250,000 gold) and complete the quest associated with it. You will be a kid during the quest and will wake up looking 20 years old again (approximately).
