Getting rid of acne can be one of the toughest things to do. There are so many products out there that promise to clear your skin right up, but only a fraction of them actually get the job done. Spot treatments are typically the most affective, and who better than beauty pro Kylie Jenner to reveal which magical product she uses for almost instant results.

In a recent Snapchat story, the 18-year-old shared her shockingly inexpensive secret for getting rid of acne. As someone with nearly flawless skin who has a sold-out Lip Kit and is constantly sharing her tips and tricks on social media, it's obvious that this young star knows what she's talking about when it comes to beauty and skincare.

Jenner uses Mario Badescu's Drying Lotion, which only costs $17 a bottle. Compared to some of her usual go-to luxury products, this is very, very cheap. In the videos, she then explains exactly how to use the product, making sure to point out that whatever you do, do not shake the bottle. Instead, dip a Q-tip into the pink solution and apply directly onto pimples as you would any spot treatment.

"You take your little swab, and you DON'T shake it," she says in one of the demo videos. "And you get down deep in there and get your solution. And then you apply."

The product is a Mario Badescu Skincare best-seller and is "world-famous" because it heels and dries pimples out "virtually overnight." The lotion is made up of calamine, salicylic acid and "quick-acting acne-zapping ingredients."

Turns out, Jenner isn't the only fan of this miracle product. "Beauty editors and skin care junkies love this product because it works," Popsugar wrote. "It reduces the size of the blemish and the redness overnight and can even bring blemishes to the surface for easier extractions."

Since the Kardashian-Jenner sisters are known for being trendsetters, especially in the beauty world, Popsugar decided to reach out to one of Mario Badescu's PR managers to see if her snaps sparked any sales.

"After Kylie snapped we immediately started receiving phone calls and there was an instant uptick in sales," said Nicole Darmanin. "The Kylie buzz was instantaneous!"

The product is even front and center on the official Mario Badescu homepage now. "Our world famous drying lotion," the site reads. "Voted StyleCaster's go-to acne treatment!"
