Teenagers get acne because of their raging hormonal changes that come with puberty, and unfortunately if your parents had acne as teenagers it's possible you will be more prone to developing acne as well. The good news is that, for many people acne disappears almost completely by time they hit their twenties.

The type of acne most teenagers get is called acne vulgaris, and it usually shows up on face, neck, shoulders, upper back, and chest.

Even "good" stress can trigger internal chemical responses that result in acne, so plan ahead to deal with extra stress when planning a wedding, graduation, move, new job, job transfer, new baby, etc. Get help around house, take time off, exercise have fun or whatever you need to do. But be proactive.

When you control stress, you help control stress hormone cortisol - reducing its release as you reduce stress, reduces effects of acne. Activity and exercise help improve blood flow and circulation and are natural healing aids for your skin enabling improved waste management, via your skin pores.

Both blackheads and whiteheads are filled with trapped sebum and bacteria. So prevention and treatment advice for how to handle them is important.

Drink plenty of water daily. A recommendation is three to four tall glasses of mineral or filtered water. If you don't drink enough, it can lead to dehydration, which leads to dead skin cells not naturally falling off or sloughing properly. This results in blocked pores which ultimately turns into acne.
