The hair colour and freckles are easily explained away; something that is common with children and freckles is that as they grow older the freckles fade and blend with the rest of the skin (or, it's a common thing here in Australia, as I know plenty of people who have done that), and hair turns grey with age.

However, the 'reversing age' thing in regards to 'using the time and speeding it up' makes no sense, and unless old Ozpin wears contacts, he's not gonna be able to change his eye colour. I guess a fake tan could change his skin colour though?
