I seriously doubt that Dumbledore or Lupin's aging is Time Travel
related. I think Lupin's aging is related to the tremendous level of
stress he endures in his daily life and in his werewolf transformations.

To deviate slightly, let's look at how time-turners cause additional
aging. Let's say Hermione takes three classes at once using a
time-turner. While the rest of the world experiences one linear hour
of time, Hermione experiences Three consecutive hours of time. That
is, she goes to one class, time-turns back an hour, goes to the second
class, time turns back an hour, and goes to the third class. To
Herione that represents three consecutive hours, to everyone else,
that represents a single hour. To the world, Hermione is in three
places at once; to Hermione however, one Hermione goes to three
consecutive classes.

Now Herione is already two hours older that everyone else. Everyone
else lives a 24 hour day, but Hermione lives a 24+2 or 26 hour day.

Let's assume she time-times three hours for class and three hours for
homework. To her that is 6 hours, to everyone else it's 2 hours.
Expand that to three times a week across 10 months and Hermione is
(very roughly) an extra month older than every one else.

So, to age years, one would have to do an astronomical amount of
time-turning. To age one extra year over the course of three normal
years, one would have to engage in 8,760 hours of time travel, or
2,920 hours per year. For reference the average 40 hour work week is
only 2080 hours per year.

Based on this, I think it is unlikely that anyone is doing any kind of
substantial long term time travel. 

However, the books frequently points out Lupin's aging and ragged
appearance; perhaps a little too often. I'm willing to bet there will
be some significance to it, but I can imagine what it will be.

Just a few thoughts.
