What are The Scientific Causes of Adult Acne?
â€œAdult acne is often hormonal and tends to be cystic â€” so itâ€™s the hard red bumps,â€ says Rebecca Baxt, MD, a dermatologist at Baxt CosMedical in New York City and Paramus, New Jersey, and a member of the American Academy of Dermatology (AAD). â€œItâ€™s very frustrating, especially for women who didnâ€™t have acne as a teenager or just had a little and wonder, Why am I getting pimples now?â€
Why Do We Get Adult Acne, Even if We Didnâ€™t Get It as a Teen?
From genetics to lifestyle habits, a number of factors can trigger a breakout.
â€œFor both teenage acne and adult acne, there is strong evidence that the tendency for acne has been encrypted in our genes,â€ says Yoram Harth, MD, a board-certified dermatologist and the medical director of MDacne in San Francisco.
Still, the type of acne you get as an adolescent is different from adult acne. â€œWhile adolescent acne will usually appear on the forehead and cheeks, the typical areas for adult acne are the lower jaws around the mouth and on the chin,â€ Dr. Harth says.
If you have frequent acne breakouts as an adult, youâ€™re not alone. According to the AAD, as many as 50 million Americans are dealing with acne at any given time. Here are some of the most common culprits:
Hormones Fluctuating hormones around the time of your menstrual period or during pregnancy â€” or even during menopause â€” can lead to zits, according to the AAD.
Androgens in men and women may contribute to acne breakouts. The AAD notes that these hormones send the oil glands into overdrive, changing those skin cells that surround your hair follicles.
Family History If one of your parents or siblings has acne, you may have a genetic predisposition for it. â€œSevere acne with scarring definitely runs in families,â€ Baxt says.
Diet and Lifestyle An unhealthy diet with a lot of sugar and alcohol may make your acne worse, Baxt says. â€œI'm not going to say that they cause it 100 percent, but I do see a lot of people who improve their diet and their acne gets better,â€ she says.
The American Heart Association (AHA) recommends a maximum daily intake of 6 teaspoons (tsp) of added sugars a day for women and 9 tsp per day for men. Keep in mind that sugar can be sneaky in food labels. Be on the lookout for these other names for sugar:
- Corn syrup
- Fruit juice concentrate
- Malt sugar
- Sugar molecules, such as glucose, sucrose, maltose, and lactose
Yet another dietary consideration is your daily sodium intake. â€œSome doctors suspect that sodium has consequences for skin because of iodine,â€ says Harth. The Advances in Dermatology and Allergology article notes there may be a link, though more research is needed. Still, limiting your sodium intake is part of a following a healthy diet and can help reduce your risk for high blood pressure, notes the AHA, which recommends no more than 2,300 milligrams (mg) of sodium per day and ideally a maximum of 1,500 mg of sodium per day. â€œTo reduce iodine-rich salt, it is best to stick to low-sodium versions of packaged foods,â€ says Harth.
Whatâ€™s the Best Way to Treat Adult Acne?
It goes without saying that managing stress, along with following a healthy diet and lifestyle, are among the controllable factors that can trigger acne. Trading in processed, high-carb, and high-sugar foods for whole plant-based ones can help get your skin on the right track.
Aside from diet, itâ€™s important to keep your stress level under control. Meditation, reading, and other relaxing activities can help.
The AAD also recommends the following:
- Wash your face twice a day. Also, be sure to use a cleanser after working out or after any activity where youâ€™re working up a sweat.
- Avoid skin-care products that contain alcohol. These can be too trying for the skin and end up doing more harm than good.
- Shampoo regularly. If you have oily skin and hair, do so daily.
- Avoid direct sunlight and tanning beds. Too much sun can have a drying effect on the skin.
- Limit touching your face during the day. This action can spread oil from your hands to your face.
A dermatologist may recommend birth control pills or prescribe spironolactone, a blood pressure medication also prescribed for acne, to help reduce breakouts, according to the AADâ€™s 2016 guidelines for treating acne. Or you may be a candidate for isotretinoin, a prescription medication for severe acne. There are also other options, like injections, oral or topical antibiotic treatments, laser and light treatments, and chemical peels, Baxt says.
If you want to try over-the-counter acne medication options first, Baxt recommends this regimen: Use a 5 to 10 percent benzoyl peroxide wash once a day and a 2 percent salicylic acid wash once a day. Then alternate applying a benzoyl peroxide gel or adapalene gel â€” a prescription-strength retinoid treatment thatâ€™s now available over the counter â€” every other night. Keep in mind that benzoyl peroxide can bleach your pillowcase, and adapalene may make your skin sensitive to waxing and the sun, so sunscreen is a must, Baxt says. It may take two to three months of following any acne treatment program to see the full effects, she adds, so be patient.
Oral contraceptives may also offer more long-term solutions to regular acne breakouts, thanks to the added hormones estrogen and progestin, which may help tame hormonal fluctuations that could contribute to your acne, according to the AAD. Be aware, however, that oral contraceptives can cause side effects, such as nausea and bloating, especially when you first start taking them, per the Mayo Clinic. Women over age 35 who smoke should also ask their doctors about the risk of blood clots when taking birth control pills, notes the AHA.
More severe acne breakouts that donâ€™t respond to the aforementioned methods may require a prescription from your dermatologist. The AAD notes that your dermatologist may prescribe prednisone to treat acne fulminans, a severe type of acne. For stubborn cysts or nodules, your derm may inject a corticosteroid into the affected area. For blackhead or whiteheads that arenâ€™t responding to medication, your derm can use acne extraction to clear the blemishes.
The Key Takeaways on Preventing and Treating Adult Acne
While you canâ€™t control your genes, you can control the diet and lifestyle habits that may contribute to adult acne breakouts. If youâ€™re not seeing results, though, it may be time to see a dermatologist. â€œTreatment for adult acne should start with a medical-grade topical skin-care routine that is personalized for the skin type and acne severity,â€ says Harth.
