BTL EXION 的身體治療頭多功能有效針對皮膚鬆弛及身體局部脂肪，專利組合技術單極射頻及聚焦超聲波技術可刺激自身透明質酸的產生，熱能和機械能刺激針對位於網狀真皮最活躍的纖維母細胞，纖維母細胞增加製造透明質酸以及膠原蛋白和彈性蛋白的生成，治療身體皮膚鬆弛；另外，治療頭內置ACTIVE COOLING保護皮膚表層，令熱力進入皮下脂肪組織深層而不影響皮膚，有效加熱至45°C，令到脂肪細胞凋亡和隨後的脂肪層減少。

The BTL EXION body treatment head effectively targets skin laxity and localized body fat with its multifunctional capabilities. The patented combination of monopolar radiofrequency and focused ultrasound technology stimulates the production of endogenous hyaluronic acid. Heat and mechanical energy specifically target the most active fibroblasts located in the reticular dermis. This increases the production of hyaluronic acid, collagen, and elastin, treating skin laxity. Additionally, the treatment head features ACTIVE COOLING to protect the skin's surface, allowing heat to penetrate deeply into the subcutaneous fat tissue without affecting the skin. This effectively heats the tissue to 45°C, promoting apoptosis of fat cells and subsequent reduction of the fat layer.
