For all that Pinterest gives us in the way of beauty inspiration, healthy recipes, et al., occasionally I come across a face-palm-worthy post that makes me want to scream, "DON'T DO IT" at my computer screen. #PinterestFails are practically a rite of passage, but when it comes to, say, rubbing hand sanitizer on your face because a user said it helped them get rid of a zit, we cross into a gray area of skin safety.
I'll admit to dabbing toothpaste on a pimple in the hopes of shrinking it (haven't we all?), but when do we say when? Or perhaps the real question is this: Which of these so-called acne hacks actually work, and which ones are actually causing more damage?
To find out, we ran some of the most popular DIY pimple tips by New York City dermatologist Julie Russak, MD. Below, find her verdict on everything from good old toothpaste to crushed-up aspirin, and please—please—DIY away your blemishes accordingly.
The Hack: Toothpaste
Yes, a dab of Colgate can dry out a zit in a pinch, since it has antibacterial and oil-absorbing properties. But it can be overly drying if you overdo it, says Russak. (Plus, most run-of-the-mill toothpastes contain other chemicals and ingredients that have no business being on your skin.)
The verdict: While it's not the worst one out there, you're better off saving this tip for emergency situations.
The Hack: Crushed Pepto-Bismol
"Applying this as a mask mixed with a little bit of water could help reduce acne marks and inflammation," says Russak. Still, as with toothpaste, it's best to be wary about products that weren't intended for your complexion.
The verdict: "I would suggest visiting a dermatologist instead to address concerns," says Russak.
The Hack: VapoRub
"This will help reduce the size of a pimple overnight—as long as there is no broken skin—but long-term use is not suggested, as one of the main ingredients is petrolatum (petroleum jelly) which will cause more acne breakouts," explains Russak. Petrolatum is heavy and greasy, which can aggravate oily complexions.
The verdict: File this under Vaseline's many uses—just take care not to overdo it.
The Hack: Listerine
Do you really want to put something that burns so much in your mouth on your skin too?
The verdict: It's a tad too harsh. "While the ingredients found in Listerine (eucalyptus, alcohol, and thyme) can kill bacteria that causes acne, using too much could cause irritation, especially to sensitive skin," says Russak.
The Hack: The Gel From an Advil Liqui-Gel
This hack has been a runaway hit on Pinterest, and Russak says there might be good reason behind that. "In an emergency situation, this remedy will decrease redness and the size of a pimple," she says, due to its anti-inflammatory ingredients.
The verdict: It works, but save it for an emergency situation, and try to stick with topical acne treatments on the regular.
The Hack: Hand Sanitizer
Confirmation that hand sanitizer is officially the worst: "The alcohol in hand sanitizer is very drying and actually won’t even penetrate into the acne," Russak says. "It will just cause irritation."
The verdict: Don't do it.
The Hack: Hydrogen Peroxide
The chemical concentration is so strong that it might do even more damage. "It can dry out your skin, which can lead to premature aging and increase the likelihood of acne scarring," says Russak.
The verdict: Save it for cuts, scratches, and clothing-stain removal.
The Hack: Crushed Aspirin Mixed With Lemon Juice
Since Aspirin is salicylic acid—a common blemish-fighting ingredient—this hack has some credibility behind it. "Aspirin increases cellular exfoliation and is antibacterial," says Russak, who adds that the vitamin C in lemon juice can brighten sun damage and existing acne scars.
The verdict: It's a great tip, but Russak says you'll still get more reliable results with a derm-administered chemical peel.
