A woman says a new trend called mewing - involving tongue exercises - has changed her face so she's no longer getting filler and implants.
Jessica Madrigal, 27, was disappointed she didn't have a very prominent jawline and jealous of her mum and sister's.
She would fall asleep with her mouth open which she believed "wasn't helping" in her quest for a more defined jawline.
But when she came across a video detailing a unique facial structure trick, called 'mewing' she knew she had to give it a go.
Mewing involves placing your tongue on the roof of your mouth, near the front teeth, and biting down naturally at the back of the jaw throughout the day, for as long as feels comfortable.
It took Jessica two months of mewing before she began to get used to it and it became natural to do.
Jessica combined this with sleep tape to keep her mouth closed at night and a small amount of physical exercise at the gym, and soon began to see results.
She kept her tongue in that position throughout the day for 15 minute periods and looking at her phone reminded her to do it.
Eventually she was also able to sleep with her mouth closed without the assistance of the tape.
Jessica claims her efforts have changed her face shape and given her a more defined jaw line.
Jessica, a teacher, from San Diego, California, US, said: "I've been doing it for two-and-a-half years now and I feel so much more confident.
"Before I wanted fillers, implants and a nose job and now I really like how I look.
"At that time before, it wasn't something I could just spend money on and now I don't even want to anymore.
"I started mewing in 2020 and a lot of people started to tell me that I looked different.
"I feel like it's helped changed my smile and side profile.
"I've always been smaller and petit, but my face wasn't defined - my mum and sister both have defined jawlines and I was confused why I didn't.
"Then in 2020 I found this video about mewing and this guy had before and after pictures and it was a video about good habits to get into.
"It was about making sure my tongue was in the proper position.
"At first it felt a little bit difficult with pressure at bridge of my nose and I wasn't used to breathing with my mouth closed.
"But I used a little technique where I said the start of the Spanish letter Ñ -pronounced 'enye' - and that helped it become more natural."
Jessica used to sleep with her mouth open due to sinus issues and decided to research sleep tape.
She also makes sure she is continuously working her jaw by chewing gum and eating food evenly on both sides of her mouth.
Jessica shares videos of her mewing journey on TikTok - where some people have said they don't see a difference in her.
But she claims friends and family soon noticed her changes - and say she looks "younger".
