We all know how to brush our teeth, right?
Well, according to one doctor, we could actually be giving ourselves spots and causing breakouts on our faces just by brushing our teeth at the wrong time.
The doctor, who regularly posts health and beauty videos on TikTok and is known online as Dr Mehss, claimed you should never brush your teeth after you've already washed your face, because you could end up transferring bacteria from your mouth onto your skin - which in turn could cause spots to grow.
Instead, the doctor said we should all be brushing our teeth first and then starting on our skincare routines, as this will kill any bacteria around your mouth when you wash your face.
Dr Mehss posted a video on her @dr.mehss TikTok account in which she shared a series of pictures of people with spots around their mouths, and said: "POV [point of view]: You don't brush your teeth before washing your face."
And she expanded on her claim in the caption of her video, where she explained: "Dermatologists and dentists agree - brushing your teeth should always come before washing your face.
"The bad bacteria from a tooth or gums can spread to your face while brushing and cause skin irritation and breakouts. So after brushing your teeth, when you wash your mouth, most of the bacteria spread from your mouth to your face will easily go away.
"Also, toothpaste residue can irritate the skin."
Dr Mehss' video has left people gobsmacked, as many had no idea that their tooth brushing routine was having such an impact on their skin.
One person said: "I literally have that on my face right now, I always forget to brush my teeth first."
While another wrote: "Oh my god, I've been getting a rash near my mouth and this is probably why!"
And a third said: "Wait what? I'm nearly 40 and no one told me this. I have always had the exact same spot pattern."
Others claimed they still get spots around their mouth even when they brush their teeth before washing their face, while some commenters offered alternative solutions - such as putting Vaseline around the mouth to create a protective barrier.
Someone suggested: "One thing that has helped me is to do a good barrier of Vaseline on/around my lips when brushing."
