Teenagers are most prone to a type of acne called called acne vulgaris. It happens when skin pores that contain oil glands, which normally lubricate the skin and hair, become clogged with excess oil and bacteria.

When a pore gets clogged, closes and then bulges out, the result is a whitehead.. Pores which get clogged but stay open become blackheads.

Pimples are the result of dead skin and bacteria getting under the surface skin, instead of beling sloughed off.

But it’s not all genetics. You can reduce acne by regular cleansing, a healthy diet and moderate exercise.

The bacteria that causes acne can be transferred via wet washcloths, so machine wash them every day or two.

Stress and sunburn encourage acne.

Makeup encourages acne; try to use less makeup, use it only on special occasions and clean if off very thoroughly.
