Picture this: a liquid tonic that promises to clearallof youracne.

The stuff of dermatologists' and cosmetic chemists' dreams, right?

“There are small trials that show benefits in treating acne.

While research is very limited, it is certainly promising,” Bhanusalipreviously toldAllure.

Not to worry, there’s no blood or menstrual cycles involved in this TikTok hack.

It went viral for one obvious reason: no one ever uses a tampon to remove theirnail polish.

It’s not really any different than using just a regular cotton ball or swab.

The stuff of sexy time aka lube has no place on your face.

I repeat: lube does not belong on your face!

You should never be giving yourself lip service or any kind of aesthetic rejuvenation at home.

Don’t try at this home.

We appreciate the creativity with thisfoundation blending hack, but is it really necessary?

Helpful for every day?

We’ve got another too-good-to-be-true acne cure, y’all: sea salt spray.

TikTok user@aubyrnjadeart’s acne-clearing success story follows the classic plotline of any fairytale.

First, we’ve got the problem: she “tried everything to cure [her acne].”

Don’t play cosmetic chemist at home, like.

Devgan says using this tool “also poses a risk of creating scars and pitting.”

Even more worrisome is that plasma pens aren’t even monitored by the FDA.

Let’s be real: we’ve all struggled to draw that perfect cat-eye.

Getting them to look identical is a whole other story, though.

Well, TikTok creator@meredithduxburysure thinks so.

The creator has made her mark on BeautyTok with her excessiveliquid foundation routine.

The real kicker is the final step of her technique: she blends it all in with her hands.

I think we’ll pass on calling this a life-changing hack, but it sure is entertaining to watch.
