As mentioned above, genetics are thought to play a major role in your susceptibility to acne. However, using the best acne products and taking good care of your skin can help you prevent worsening acne and scars later in life. Check out these other known acne causes and aggravators and see how to prevent acne by cutting some of these out of your life:
16. Know this quick fix. If you wake up the day before school starts with a big honking zit, your doc may be able to help. If you can swing it, your best bet is to head to the dermatologist. "There is an almost immediate fix, and that's an injection with a dilute strength of cortisone done by your dermatologist," says Dr. Robin Evans, a dermatologist at SoCo Dermatology in Connecticut. "It's quick and easy, with minimal discomfort, and it usually goes down within a day." This isn't an easy or cheap option, obvi, but when it's an emergency — like, you have a huge whitehead on the tip of your nose the day before senior portraits — it might be worth it.
15. Try the 3-step solution. If you have acne, dermatologists recommend fighting it with a three-step regimen: a salicylic acid cleanser, a benzoyl peroxide spot treatment, and a daily moisturizer. Benzoyl peroxide works by fighting the bacteria that causes acne. It causes an exfoliating effect that might cause some slight peeling and can dry out your skin. It's great for mild cases of acne, and you can get it without a prescription — many drugstore acne washes, creams and gels contain benzoyl peroxide. Prescriptions creams that contain higher doses of benzoyl peroxides such can also be prescribed by a doctor for more severe cases. Salicylic acid dries out the skin and helps exfoliate it to make dead skin cells fall away faster. It's good for mild cases of acne, and is available without a prescription. Many drugstore acne creams, washes, and gels contain salicylic acid, but stronger versions are also available in prescription form. It can dry up your skin and cause redness and peeling.
The spots that linger after a pimple has healed are caused by inflammation that has disrupted the skin's natural healing process. "When your skin is opened up (like when you pop a pimple) and then closes back together, you can get abnormal pigmentation, texture, and tone that looks different from the rest of your skin. Sometimes the broken blood vessels that remain after an acne lesion fades can result in a mark," says Dr. Bowe. For a number of people who are able to refrain from picking, inflamed pimples or blemishes can still leave a dark brown or red mark — but these naturally fade over the course of a few months, notes dermatologist Heather C. Woolery-Lloyd, MD.
A BHA product often cited includes salicylic acid, it must be between a pH between 3 and 4 to work. A BHA works to slough (to get rid of) off dead skin cells and encourage new skin growth. As a result, you may experience dry skin and scaliness around your acne, but this will dissipate over time as your skin begins to regenerate faster. Use this in a cleanser or spot treatment daily on the acne-affected areas of your skin.
Avoid touching or rubbing your face, since that can make acne worse. Try to keep your cell phone from touching your face, too. Use earbuds instead of having the phone against your skin. Also, don't lean your face on your hands, which may carry oils and germs that can irritate blemishes. Sweat can also make acne worse. Sweaty after exercise? Wash up.
Hypo-pigmentation is characterized by the light spots that result from a lack of melanin. With this type of skin damage, melanocytes are depleted from the injured area or lose their ability to produce melanin. This occurs when healthy skin has been replaced with scar tissue. Because scar tissue has a light pink color, it’s more noticeable on people with darker skin tones.
All three dermatologists suggested that the best solution for boxcar or rolling scars are in-office procedures. Dr. Day, for instance, suggestedEndyMed Intensif, which uses microneedle radio frequency to remodel the skin by delivering heat into the skin to stimulate collagen and elastin production. For at-home treatments, however, Dr. Day turns to Olay's DIY microdermabrasion kit. It comes with both a foam head and crystal polisher, which claims to exfoliate 7 times better than a typical scrub and thoroughly cleanses the face to prevent future breakouts.
Use gentle skincare products. A lot of the time, people are so desperate to get rid of acne scars and skin discolorations that they will use all manner of abrasive products and methods which can irritate the skin and make the situation worse. Try to listen to your skin -- if it's reacting badly to a particular product, you should stop using that product immediately. Stick to gentle facial cleansers, make-up removers, moisturizers and scrubs that soothe your skin rather than inflame it.
Facials can be an effective way to get rid of non-inflammatory or comedonal acne (whiteheads and blackheads). Comedones occur when pores get clogged with oil and dead skin cells. Facial exfoliation takes off the top layer of skin, which unclogs pores and helps oil flow naturally through the follicles, thus avoiding future breakouts. Extractions remove the existing comedones, which both helps your appearance and also lessens the likelihood developing a pimple (which occurs when a comedone becomes inflamed).
Avoid picking at spots and scars. Though it may be tempting, picking at your scars interrupts the process by which your skin naturally heals and can worsen their appearance. Picking at existing pimples, meanwhile, can cause your skin to scar in the first place, as bacteria from your hands may be transferred onto your face, causing it to become inflamed and infected. Therefore, picking should be avoided at all costs.
Apply fresh lemon juice. Lemon juice has natural skin bleaching properties, and can help to effectively lighten your acne scars. Simply combine equal parts lemon juice and water and apply this liquid directly onto your scars, avoiding the surrounding skin. Wash off the lemon juice after 15 to 25 minutes or you could put the lemon juice on overnight as a mask.
Doxycycline is another of the tetracyclines that is equally effective in treating acne. It comes in generic versions and also as the branded Doryx and Acticlate which are easier on the stomach. Originally FDA approved for the treatment of rosacea, Oracea is a non antibiotic dose of doxycycline that is often used as an acne treatment, as well. Taken orally, it can be used as solo therapy or in combination with a topical acne treatment regimen. More severe cases of acne might need higher doses of doxycycline, but since Oracea is not an antibiotic, many patients can be “down-graded" to Oracea after improvement and it is suitable for longterm use as it does not cause antibiotic resistance.
48. Clean your makeup brushes every two weeks or so. The amount of product and bacteria build up that happens within two weeks is frightening, and the longer you wait to clean the brushes the longer you’re putting the bacteria right on your skin, causing breakouts. Use warm water and a mild anti-bacterial soap to clean your brushes, laying flat to dry to avoid any warping that can happen.
Can’t use the good stuff: The best medications for clearing acne include topical retinoids like Differin and Retin-A. The strong chemicals that are used in exfoliants can cause severe inflammation and sun irritation when combined with these medications. This means that you will have to choose between facials or proper medications. The choice is yours.
This powerful pink acne treatment is formulated with 10 percent Sulfurthe highest level allowed to effectively fight acneto help clear skin of blemishes and acne-causing bacteria. It also contains AHAs to reduce the appearance of enlarged pores and help control sebum production. This acne treatment also prevents future breakouts, resulting in a clearer complexion.
Consider exfoliating with baking soda. Baking soda can be used to exfoliate the skin and minimize the appearance of acne scars. All you need to do is mix one teaspoon of baking soda with two teaspoons of water to form a liquid paste. Apply this paste all over your face and use gentle circular motions to rub the baking soda into the skin, concentrating on the scarred areas, for about two minutes. Rinse off with warm water and pat the skin dry. 
With a blend of potent antioxidants, this serum is loved by beauty editors and dermatologists alike. Vitamin C plays a leading role: "The powerful ingredient has been shown to brighten dull skin and lighten brown spots. It may also be helpful in lightening a dark scar," says Joshua Zeichner, the director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. The formula also includes vitamin E. "Vitamin E is a fatty vitamin that has both antioxidant and skin-protecting properties. It helps seal cracks in the outer skin layer and may help repair a damaged skin barrier and improve the appearance of scars after the initial wound has healed," Zeichner says.
Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
13. You're still a sun-worshipper. You're probably already aware that lying out in the sun and going to tanning beds cause skin cancer, but if that still hasn't stopped you from hitting the beach without sunscreen or the proper protective gear (aka that chic sun hat), perhaps this will. Contrary to popular belief, the sun isn't healing your acne, it's actually making it worse. What happens is, as your face gets red from the sun, it makes any breakouts you might already have blend in, creating the appearance of clearer skin. But what's really going on is the sun causing your skin to dry out and triggering more oil production, which can lead to more zits.
Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all teenagers during puberty -- the only exception being members of a few primitive Neolithic tribes living in isolation. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.
