Which type of skin glands are most affected by the hormonal changes that occur during puberty?
Anna [14]

Apocrine sweat glands  are most affected by the hormonal changes that occur during puberty.

What is puberty ?

Between childhood and adulthood, puberty is a time of rapid growth, the emergence of secondary sexual traits, the attainment of fertility, and significant psychological changes. Although the order in which pubertal changes occur is fairly predictable, their exact time varies greatly.
