The aging of facial structures depends on genetic, anatomic, chronologic, and environmental factors that affect the skin and underlying tissues. Microfocused ultrasound with visualization (MFU-V) has emerged as a safe and effective treatment for skin laxity. As the nutritional status may contribute to skin aging, it would be interesting to evaluate whether different dietary patterns can also influence the response to MFU-V treatment for skin laxity.
The aim of this study is to compare the outcome of MFU-V therapy between omnivore and vegan patients.
Twenty-seven vegan and twenty-seven omnivorous women who underwent MFU-V treatment for laxity of lower face and neck were enrolled. The clinical outcome was evaluated using the FLR (Facial Laxity Rating) scale after 3 and 6 months from treatment.
At baseline, no significant differences were found in terms of FLR scale in both treated sites. After 3 months, reduction in FLR scale was significantly lower for vegans both on face (P = .04) and neck (P = .004). At 6 months, vegan patients had a worse clinical outcome on lower face (P = .001) and neck (P < .001).
The present study suggests that a vegan diet may negatively influence the outcome of a MFU-V treatment.
面部结构的老化取决于遗传、解剖、时间和环境因素，这些因素会影响皮肤和其下的组织。微聚焦超声可视化（MFU-V）已成为一种安全有效的皮肤松弛治疗方法。由于营养状况可能会影响皮肤老化，因此评估不同的饮食模式是否也会影响 MFU-V 治疗皮肤松弛的效果将是很有趣的。
本研究旨在比较杂食者和素食者患者接受 MFU-V 治疗后的效果。
招募了 27 名素食者和 27 名杂食者女性，她们接受了 MFU-V 治疗以改善下面部和颈部的皮肤松弛。治疗后 3 个月和 6 个月时，使用面部松弛评分（FLR）量表评估临床效果。
在基线时，两组治疗部位的 FLR 评分均无显著差异。治疗后 3 个月，素食者的面部（P =.04）和颈部（P =.004）的 FLR 评分降低幅度明显较低。治疗后 6 个月，素食者下面部（P =.001）和颈部（P <.001）的临床效果更差。
本研究表明，素食饮食可能会对 MFU-V 治疗的效果产生负面影响。
