Globally, acne affects approximately 650 million people, or about 9.4% of the population, as of 2010.[158] It affects nearly 90% of people in Western societies during their teenage years, but can occur before adolescence and may persist into adulthood.[19][20][23] While acne that first develops between the ages of 21 and 25 is uncommon, it affects 54% of women and 40% of men older than 25 years of age,[47][159] and has a lifetime prevalence of 85%.[47] About 20% of those affected have moderate or severe cases.[2] It is slightly more common in females than males (9.8% versus 9.0%).[158] In those over 40 years old, 1% of males and 5% of females still have problems.[20]
How to Handle It: Think of these as bigger, pissed-off whiteheads. Your best bet, says Zeichner, is to stock up on benzoyl peroxide, which kills the bacteria. A spot treatment like Murad Acne Spot Fast Fix ($22) should do the trick. Also, try not to pop them — as tempting as that may be. Since they're inflamed, they're more likely to scar if you go the DIY route.

If your acne is severe, painful, or refusing to get lost, you may just be beyond what an over-the-counter treatment can do. Not only can a professional set you up with the really powerful stuff, but also Fitz Patrick explains that “working closely with an aesthetician or dermatologist means you can keep tweaking a routine to make it work best for you.”
Kathyrn Bowling’s son Gus was only two weeks old when she first noticed red bumps spreading on his face: newborn acne. At the time, the Atlanta mom wasn’t concerned about something so common (and harmless) as baby acne. I was worried about so many other things, like how much he was eating and whether I would get enough sleep,” she says. “In the grand scheme of things, a few bumps on his face didn’t seem too bad.”
Combined oral contraceptives. Four combined oral contraceptives are approved by the FDA for acne therapy in women who also wish to use them for contraception. They are products that combine estrogen and progestin (Ortho Tri-Cyclen, Yaz, others). You may not see the benefit of this treatment for a few months, so using other acne medications with it the first few weeks may help.
We suggest avoiding spot treatments. “Benzoyl peroxide, when placed on red spots, can actually cause more irritation and inflammation to the area. It’s best used to prevent red bumps and pustules, and applied all over the area you want to treat,” said Townsend, who was also quick to naysay a spot-treat-only approach: “Acne affects all of the pores. If someone is going to spot treat against my advice, I still suggest they spot treat one day and treat the whole face the next.”

Washing your face with regular soap isn't enough to make acne better. The best face wash for acne is effective at removing oil and dirt, but still gentle enough to use regularly without overdrying your skin. Look for topical acne medication ingredients salicylic acid and/or benzoyl peroxide in your face wash and use gentle, nonabrasive cleansing techniques.
Pimples are raised red spots with a white center that develop when blocked hair follicles become inflamed or infected with bacteria. Blockages and inflammation that develop deep inside hair follicles produce cystlike lumps beneath the surface of your skin. Other pores in your skin, which are the openings of the sweat glands, aren't usually involved in acne.
