Answer
Puberty is the period when the reproductive tissues mature as general growth slows; new body hair and oily skin occur in both sexes.
Puberty: the period during adolescence when, as the rate of general body growth begins to slow down, the reproductive tissues begin to mature.
Any two changes common to both boys and girls: (1) Thick hair grows in new parts of the body, such as the armpits and the genital area between the thighs, and it can become darker; thinner hair can also appear on the legs, arms and face. (2) The skin frequently becomes oily and pimples may appear. (Also acceptable: they become conscious and aware of their own bodies and those of others in new ways.)
