At what age does puberty stop?
It can take up to 20 years of age for all the changes that happen during puberty to take place.
Puberty doesn’t happen all at once — it happens in stages. So a girl or guy may show some signs of puberty at an early age (like breasts beginning to grow or a voice that’s starting to crack), but may not show other signs of puberty until she or he is much older (like getting a period or growing facial hair).
