Does chocolate cause acne? Skin care myths and facts

Skin-care misconceptions, fallacies, and flat-out wishful thinking are as plentiful as cleansers in a drugstore. Some are long-held beliefs passed down for generations, such as the notion that squeaky-clean is a virtue. Others are convincing for their grounding in “modern technology.” But with help from doctors (and years of research), the truth has at last been separated from the…eh, not so much.

Rumor: Squeaky-Clean Skin Is, Well, Squeaky-Clean
Reality: Overzealous face washing, whether more than twice a day or with products that leave your skin as tight as a drum, can actually cause damage, said Dr. Cheryl Karcher, a dermatologist in New York City. 

“The water-cleanser combo can strip skin of its natural oils and compromise its barrier, which can set you up for irritation and dehydration,” she said.

Therefore you should avoid cleansers that contain harsh surfactants, which rid skin of too much oil and leave it so dry that it feels taut—and might just squeak if you dragged a finger across it. Some common surfactants include sodium lauryl sulfate (SLS), sodium lauryl ether sulfate (SLES), and ammonium lauryl sulfate (ALS). 

Instead of these, look for gentler cleaning agents, which may be glucose-based or derived from coconut oil. They can take off makeup but still maintain skin’s suppleness. These include coco betaine, cocamidopropyl betaine, coco glucoside, decyl glucoside, and sucrose laurate. And if you use cleanser at night, a quick splash of cool water alone will suffice in the morning. (However, if you’re a morning gym-goer, you’ll need to cleanse again, since sweat can clog pores.) For midday greasiness, try oil-blotting papers or waterless cleansing wipes.

Rumor: Botox Can Prevent Wrinkles
Reality: Theoretically, yes. But no long-term studies support this claim. 

“If you relax the muscles that continually contract, you’ll be less apt to see creases over time,” said Dr. Fredric Brandt, a cosmetic dermatologist with practices in New York City and Coral Gables, Florida. “But other strategies, like using sunscreen and keeping up proper skin care, are more reliable and certainly less expensive options for fending off wrinkles.”

If you still feel compelled to go under the needle, Los Angeles and New York City dermatologist Karyn Grossman advises beginning Botox treatments no earlier than when fine lines first appear, generally in your 30s.

Rumor: Oily Skin Doesn’t Wrinkle as Much as Dry Skin
Reality: The research isn’t definitive, but this supposition seems to make sense. 

“Oily skin may fend off wrinkles more easily because it tends to be thicker, which affords more natural protection against sun damage,” Brandt said. 

Dr. Ruthie Harper, an internist in Austin, Texas, ties the phenomenon to hormones. 

“Women with oily skin may have higher testosterone levels,” she said, “which can help protect against diminished collagen levels and, in turn, wrinkles.”

But this is not to say that oil-prone skin doesn’t ever look old. And factors such as sun exposure and smoking speed up the aging process and cause wrinkles, regardless of skin type.

Rumor: Junk Food Causes Acne
Reality:
“So far, no studies have shown a direct correlation between junk food and breakouts or acne,” said David Bank, a dermatologist in Mount Kisco, New York. 

And most of the other dermatologists interviewed for this story agree with Bank. However, associations have recently been made between the consumption of high-glycemic foods (typically foods that contain refined carbohydrates) and breakouts among people who are acne-prone. 

Why? Inflammation is known to aggravate acne, and high-glycemic foods (such as white rice, sweets, and sugary drinks) can raise blood sugar and insulin levels quickly, leading to inflammation. And though dark chocolate may in fact offer multiple health benefits, milk chocolate is being called into question as a possible cause of acne. 

In a recent study published in the Journal of the American Academy of Dermatology, Italian researchers found that drinking more than three glasses of full-fat or skim milk a week could increase the risk of moderate to severe acne in those who are predisposed to flare-ups. 

The key, says Harper, is to limit these possible triggers and balance them out with foods and beverages that contain anti-inflammatory benefits, such as green tea, broccoli, and fish rich in omega-3 fatty acids, which have been linked with a 32 percent decreased risk of acne when eaten at least once a week.

Rumor: For Best Results, Use Skin-Care Products From the Same Line
Reality: You don’t need to, said Bank: “Generally this is just clever marketing.” 

There are, however, certain ingredients that companies pepper throughout a certain line that are especially efficacious when used together. For example, you may find a blemish kit that contains an anti-acne cleanser with salicylic acid to help unclog pores and a gel treatment with glycolic acid to prevent future pimples. 

“If you’re trying to address a specific problem, like acne-prone skin or dark spots, this prepackaged approach may make it easier,” Grossman said.

Rumor: You Can Get Rid of Cellulite
Reality: “No cellulite fix is permanent,” Dr. Howard Sobel, a dermatologist in New York City, said. 

Some treatments might minimize the look of cellulite, such as creams that contain aminophylline (which helps break down fat cells) and massaging devices that iron out fat cells somewhat so that they don’t appear as pronounced. But these remedies last, at best, a few months. 

“Even liposuction, which removes excess deep-fat deposits, doesn’t necessarily improve the surface of the skin to the degree where the dimpled effect is invisible,” Sobel said. 

There is, however, a ray of hope: Cellulaze, a laser treatment that cuts the little vertical bands under the skin that are attributed to the dimpling effect and smooths them out. The treatment recently received clearance from the U.S. Food and Drug Administration (FDA) for treating cellulite long-term, says Barry DiBernardo, a plastic surgeon in Montclair, New Jersey, and the lead clinical investigator of the FDA trials of Cellulaze. 

But it doesn’t come cheap. The cost can run from $3,000 to $8,000 for the one session that you’ll need.

Rumor: The Higher the SPF, the Longer You Can Stay in the Sun
Reality: No, no, no. SPF isn’t an indication of how long a product protects you from the sun’s blistering, cancer-causing UVB rays but how well it does so. What’s more, SPF doesn’t refer to the product’s ability to shield you from UVA rays, which, in addition to causing skin cancer, have been linked to causing wrinkles. 

Your best bet: sunscreen labeled “broad-spectrum” (which means it covers both UVA and UVB rays) with an SPF of 30. Why? While an SPF of 15 screens out only about 93 percent of UVB light, an SPF of 30 filters out 97 percent—and those any higher don’t offer much more benefit. Remember: Any sunscreen will be effective only if it’s reapplied at least every two hours; use at least a teaspoon of it on your face and a shot-glass–size amount on your body.
