Baba Yaga is usually shown as an ugly old woman and quite unclean. Baba Yaga is often represented as little, ugly, with a huge and distorted nose and long teeth. This can be explained by the lady's place of residence. Far from the civilized world, her hut doesn't have any modern facilities like hot running water or shower. And she has been enduring these unbearable conditions for an untold number of years, as nobody else knows the age of this lady.

However, Baba Yaga knows something that women of all times and ages have been desperately trying to learn: the secret of turning from old into young in a blink of an eye. Baba Yaga knows a recipe of a special potion that helps her when needed to turn young. Unfortunately she has been known to use this her skill not to arrange her single private life, but to misguide and deceit strangers. She is also rumoured to have only one leg, which is sometimes explained by her relation to a snake.
