Even if someone looks younger than they actualy are, they are still growing and maturing, so the comparison to Mavis is incorrect. Mavis apparent age and her biological age is the same. Whether you consider Mavis 119 (her chronological age) or 23 (the age she likes to pretend she is) it doesn't change the fact that she stoped aging at 13.
