摘要

Backgrounds and aims

Submental skin laxity (SSL), manifesting as sagging skin and double chin, can significantly affect patients’ self-perception and social interactions. While surgical treatments exist, non-invasive methods are increasingly sought for their minimal recovery time. This study assesses the safety and effectiveness of a novel microwave-based device for treating SSL, aiming to provide long-term improvements in skin tightness and appearance.

Materials and methods

Ten female patients with moderate to severe SSL underwent two treatments spaced 30 days apart using a 2.45 GHz non-invasive microwave device, with a specific handpiece. Treatment sessions lasted 10 min each, targeting the submental region. The Submental Skin Laxity Grade (SMSLG) was assessed before treatment and 12 weeks after the final session. Safety was monitored, and standardized photographs were taken for clinical evaluation.

Results

All patients showed a significant reduction in SSL, with SMSLG scores improving from a mean of 3.6 at baseline to 2.3 after 12 weeks. No adverse effects were reported, and patients experienced minimal discomfort during and after the treatment sessions. Photographs revealed visible improvements in skin tone and tightness across all cases.

Conclusions

The microwave-based treatment demonstrated significant efficacy in reducing SSL and improving skin tone with minimal side effects, offering a promising alternative to surgical interventions. This non-invasive approach provides effective outcomes in fewer sessions and may represent a new standard for non-surgical skin tightening in aesthetic dermatology.
