During puberty, the first facial hair to appear tends to grow at the corners of the upper lip (age 11–15).

It then spreads to form a moustache over the entire upper lip (age 16–17).

This is followed by the appearance of hair on the upper part of the cheeks and the area under the lower lip (age 16–18).

It eventually spreads to the sides and lower border of the chin and the rest of the lower face to form a full beard (age 17–21).

pls like and rate the ans

thanks
