From time to time, you come across some pretty dodgy health advice on social media.
From fad diets to homemade treatments, you should take every piece of online wisdom with a grain of salt.
Which is why it's so surprising that a viral post by a mother-of-two from Texas gets the thumbs up from actual doctors.
Cindie Allen-Stewart says she can cure a sunburn fast using a product from your medicine cabinet, and dermatologists agree with her.
"The next day, it’s usually gone"
Allen-Stewart was just trying to share a helpful tip about dealing with sunburns with her Facebook friends.
"I recently told a friend about a sunburn treatment that works wonders," she explained.
"She told me she had never heard about it, so I figured I'd make a post because I was sunburned recently."
There's no "trick," and it just takes one product you probably have in your home already: foamy menthol shaving cream.
Allen-Stewart says spreading the foam on a burn usually cures it in just a few hours, much faster than other treatments like cold compresses.
And the crafty mom says her skin almost never peels after a burn.
"I burn, then do shaving cream, and the next day, it's usually gone," she explains.
"You don’t want to just put it straight on your back because it’s really cold. You want someone to put it on their hand and rub it on."
After letting the foam soak on the burn for 30 minutes or so, it can be washed off with lukewarm water.
It the burn sticks around for another day, Allen-Stewart recommends repeating the treatment.
"It’s really a great moisturizer"
For once, doctors say the viral treatment actually works pretty well.
While Allen-Stewart says she learned the shaving cream treatment decades ago, dermatologists agree that it's not such a bad idea.
"If you look at the ingredients of shaving cream, it’s really a great moisturizer," Dr. Ross Radusky told Inside Edition.
"It has a lot of coconut oil, coconut butter or derivatives of it. That’s actually what gives it some of its thickness and why you sort of lather it on."
That moisture, along with ingredients like glycerin, helps repair damaged skin.
Meanwhile, the "cool" menthol soothes the pain of a nasty burn.
Doctors do warn that the cream won't treat redness and inflammation as well as medicines like low-potency steroid creams.
Plus, if you have severe, blistering burns, you should see a doctor instead of treating them yourself.
And there are downsides to using the cream too: shaving creams are known to cause acne, especially if you leave it on for more than a few minutes.
So beware of breakouts if you try this homemade cure.
And what do experts recommend to cure a sunburn? They say the best treatment is still rest and re-hydration, and wearing sunblock to prevent burns in the first place.
