2 yrs ago I had hair that was totally white and grey streaks on the sides. Today, it is lighter brown that it was in my adult life and has blond streaks from childhood color.
My bluegreen eyes had developed catgreen circles around the pupils, probably 1/16 - 1/8 thich. That has all but disappeared ... you'd probably never notice it.
My complexion has gone from hundreds of the kinds of blackheads that are embedded under the skin across my nose and cheek bones to clear.
