TikToker cuts into new makeup sponge, makes gruesome discovery

Can’t remember the last time you replaced your makeup sponge? This is your sign to buy a new one.

Kaitlyn Son, a lifestyle content creator, revealed that her Beautyblender had quickly become a breeding ground for mold — unbeknownst to her.

“Cutting open my new beauty blender to see if there’s mold,” she wrote on a now-viral December video with more than 18.8 million views.

She had noticed that her “new” pink sponge had sprouted dark splotches, making her wonder if fungi could be festering inside.

So, she took a pair of scissors and cut the cosmetic applicator in half — revealing clusters of black residue, presumably mold — prompting her to toss the Beautyblender in the trash.

The Post reached out to the makers of Beautyblender for comment.

In the comments, Son claimed to have only used the sponge one time and asked her viewers for recommendations for disposable sponges for future use.

Some viewers claimed their makeup applicators had never grown mold, while others swear by trusty brushes or their fingers to apply cosmetics out of fear of fungus.

“The mold adds to my base,” one viewer joked.

“There has got to be mold in mine bc i always forget to let it dry,” admitted someone else.

“Oh this is another thing to be afraid of thank you,” quipped another.

“I started using my hands for everything that I can cause I know my hands won’t grow mold,” one person wrote.

“How long till you should change your beauty blender?” another asked, to which Son said, “every month or two.”
