How to advance lower lip without surgery? (Photo)

To add volume to the lower lip without surgery the easiest option is HA fillers. This would give you immediate results, but they would be temporary. The fillers in this area typically last 6 months to a year depending on the selected filler. One benefit of the HA fillers is that they can be dissolved if the result is not desirable.

The position of your lips is influenced by several factors including your skeletal structure, soft tissue thickness, muscle tone, and dental occlusion. If your lower lip is still recessed after a sliding genioplasty, it could be due to the underlying dental and skeletal structure.
While mandibular advancement surgery is a common procedure to address this, it sounds like you have concerns about the space available between your teeth. In such cases, it would be beneficial to consult with an orthodontist, who could evaluate your dental alignment and potentially suggest orthodontic treatments that could help.
In some cases, a non-surgical approach like the use of dermal fillers can be considered. Injectable fillers can provide volume to the lower lip, making it appear more projected. However, this is a temporary solution and needs to be repeated periodically.
Another option could be a lip lift or lip augmentation surgery, which can change the shape and position of the lips. However, the appropriateness of these procedures would need to be evaluated by a plastic surgeon.
Overall, it's important to consult with a team of specialists including a plastic surgeon, orthodontist, and possibly a maxillofacial surgeon to understand your options and choose the best treatment plan for your specific needs.
