Not everyone can naturally change the shape of their jaw. In some cases, it's genetic or a result of aging. However, the layers of fat appearing under the chin are also associated with weight gain. A healthy lifestyle involving a nutritious diet and exercise can make your jawline appear more defined without needing a cosmetic procedure.
It's no surprise a DIY solution for such a common aesthetic topic has gained so much attention. Seeing a video with deceptive mewing before and after photos can be convincing, but trying it on your own could be harmful.
If you have cosmetic or medical concerns about your jaw, seeking the advice of a trusted dental professional is the safest option. They can provide you with a recommendation backed by years of experience and evidence-based outcomes.
