Beauty Blogger Hacks: Should You ‘Bake’ With Cornstarch or Rub Onions on Your Brows?

Beauty bloggers seem to have all the answers, and they come up with lots of genius hacks for at-home treatments. But not everything they suggest is safe or effective. Scroll through to find out which ones actually work!

On March 16, YouTuber Miriam Marroquin posted a video explaining the process of “baking” with cornstarch. (This is the process in which you excessively apply translucent setting powder — in this case cornstarch — to the parts of your face that get shiny to make your foundation stay put.)

Marroquin used a beauty blender to layer the cooking staple beneath her eyes (to set her concealer), on her cheekbones, nose and chin, and between her eyebrows. When she finished, she dusted off the extra powder for an airbrushed look.

“I did some research, and I did find mostly good reviews on it, so I thought I’d give it a try,” the blogger states in her video, which has over 20,000 views. “I think this is a [win] because it doesn’t look too white on your face. I’m totally impressed with this.”

But some experts are saying the process could have unwanted side effects. “I would not recommend cornstarch on the face. It’s food for yeast that live on the skin,” New York City cosmetic dermatologist Doris Day, M.D., told Cosmopolitan on March 29.

Some pros disagree and mention that it is even a common product in a lot of makeup. “I have no problem with cornstarch,” Dr. Elizabeth Tanzi, founder and director of Capital Laser & Skincare, tells Us Weekly. “I’ve never heard of yeast forming on an environment that is not moist.”

One product that Tanzi doesn’t recommend for “baking”? Baby powder. “It’s unhealthy to inhale,” she explains, adding, “[It] can be irritating on the lungs.”

Another at-home technique making waves on the beauty blogger circuit is onion juice. Blogger Farah Dhukai (who has over 400,000 followers on Instagram) posted a video of herself rubbing red onions over her brows with the caption, “Grow eyebrows fast!” which was quickly shared by Huda Kattan — to her 12.7 million followers.

“Onion juice has sulphur which speeds up the growth of hair and makes it thicker,” Kattan captioned the clip. “Massage onion juice on brows for 5 mins, let it dry completely, wash off with cold water or a mild cleanser. Do this everyday, careful not to get this in ur eyes!”

Tanzi recommends traditional products for growing out your brows, and warns to steer clear of onions. “Don’t use it because it can cause red and itchy irritation,” the assistant clinical dermatology professor at George Washington University Medical Center tells Us Weekly.

Instead, Tanzi suggests using something like Latisse, which was originally on the market for eyelash growth. “Latisse on the eyebrows works well, but it can stain the skin,” Tanzi warns. “Some women like that because it adds color to the brow, but for others it may not exactly match. Not to worry, the staining goes away once the Latisse is stopped.”
