1. Acne
The oil glands on your face and body produce more oil. You get pimples when the glands become clogged with dead skin cells and bacteria.
2. Voice box
Your voice box becomes bigger, and your vocal cords become thicker, making your voice sound deeper. This happens to everyone, but it is often more apparent in boys.
3. Sweat
You’ll start sweating more from your scalp and face as well as your armpits, groin, and feet.
4. Hair
The hair on your head becomes thicker, longer, and coarser. It may also grow on many other parts of your face and body.
5. Growth
You could grow up to several inches taller. If this happens very quickly, you might experience growing pains, especially at night. You also might develop muscles or gain weight. This sudden growth may cause stretch marks to appear on your body.
