The one food Dr. Schultz does recommend to avoid is iodine. "Iodine causes acne in everyone if you eat enough," he says. You can find it in shellfish, like lobster, shrimp, crab, and some greens like kelp and spinach. The different between iodine and those other "acne-causing foods" is that iodine builds up over weeks and months before it starts to affect skin.
Lin says he recommends applying egg whites directly to a pimple to shrink a breakout. “The protein in the egg will help dry out the pimple,” he says. “You can also apply honey to a breakout to calm redness. Honey is a naturally soothing ingredient with anti-inflammatory properties that helps heal the skin. Leave it on for five to 10 minutes, then wipe away with a damp cloth.”

When you think about it, consistently reaching for your go-to face towel every day is like reusing a dinner napkin over and over again. Using dirty towels can harbor bacteria, and they can even introduce new bacteria to your skin, which may lead to more pimples. Thankfully, this doesn't mean you need to reach for a new towel every single time you wash your face, according to Dr. Melissa Kanchanapoomi Levin, board-certified NYC dermatologist and clinical instructor at NYU Langone and Mount Sinai Hospital. As long as you're truly washing off all of your makeup, you can stick to switching out your towels on a weekly basis.
This article was medically reviewed by Hilary Baldwin, MD. Baldwin, medical director of the Acne Treatment Research Center, is a board-certified dermatologist with nearly 25 years of experience. Her area of expertise and interest are acne, rosacea and keloid scars. Baldwin received her BA and MA in biology from Boston University. She became a research assistant at Harvard University before attending Boston University School of Medicine. She then completed a medical internship at Yale New Haven Hospital before becoming a resident and chief resident in dermatology at New York University Medical Center.

Unwashed sheets and pillowcases lead to cross contamination which leads to pimples. Aim to wash your bedding once or twice a week to prevent bacteria from building up and affecting your complexion, suggests Dr. Papantoniou. If that seems overboard, at least aim to wash your pillowcase once a week since that's where your face rests while you snooze (and dream of flawless skin).
This treatment is performed by dermatologists and combines two different technologies — microneedling and radio frequency — for big results in eliminating acne scars. First, a topical numbing gel is applied. Then the doctor uses the microneedling device to penetrate the skin and, simultaneously, radiofrequency is delivered right to the dermis. Downtime is usually around 24 hours and then you can resume wearing makeup to cover any lasting redness.
Ablative lasers deliver an intense wavelength of light to the skin, removing thin outer layers of the skin (epidermis). In addition, collagen production is stimulated in the underlying layer (the dermis). Patients are typically numbed with local anesthetic and the ablation is done as an outpatient procedure. CO2 and erbium are the ablative lasers most often used for acne scar treatment.
Photodynamic therapy is a new acne treatment. It begins with light microdermabrasion. This is used to remove dead skin cells on the face's surface. Then, an acid is put on the skin for 30 to 60 minutes. After this period, the acid is taken off. Lastly, the skin is treated with a laser. This treatment is still being researched, but seems to give positive long-term results.

We've all heard the foods that allegedly cause acne—chocolate, fried foods, pizza, caffeine, nuts. But Dr. Schultz reminds us that in large, statistically significant studies, these have not been proven to cause zits, but there are always exceptions. "If you break out when you eat chocolate, don't eat chocolate." Same with dairy, which again, has been shown in some cases to have an effect but no concrete cause-and-effect relationship exists.


Acne is usually a temporary problem, but acne scars can be permanent. However unwelcome they may be, scars are part of the skin's normal healing process after it has been damaged by a wound or injury. Most superficial wounds heal without scarring. It's when the dermis is damaged that scars form on the skin. Learn what causes acne scars and how you can prevent them.
Acne can be a painful and embarrassing skin condition, and the scars it leaves behind are an unwelcome reminder of that. A dermatologist can help remove raised or pitted scars. While hyper-pigmented blemishes may fade after several months, you can help speed up the process. Realistically, you will not be able to make acne scars disappear in a single night, but the remedies, products, treatments, and skincare tips outlined below will certainly produce a noticeable difference over time. You just need to find the right method for your individual skin type.
Drugs: Some medications may cause or worsen acne, such as those containing iodides, bromides, or oral or injected steroids (either the medically prescribed prednisone [Deltasone, Orasone, Prednicen-M, Liquid Pred] or the steroids that bodybuilders or athletes sometimes take). Other drugs that can cause or aggravate acne are anticonvulsant medications and lithium (Eskalith, Lithobid). Most cases of acne, however, are not drug related.
