Thermage FLX® uses the latest monopolar, capacitively coupled radiofrequency system using AccuREP™ technology performed over 3 million treatments worldwide. This patented technology is designed to deliver the radiofrequency energy precisely and evenly to the skin's deep layers. This technology ensures that the heat is delivered to the right depth and at the right temperature to stimulate collagen production without damaging the skin's surface. Thermage FLX® works by separating water molecules from collagen in the dermis, giving an instant tightening effect and reduction in skin laxity. The dermis is composed of about 80% collagen, with type I collagen being the most abundant which is responsible for providing support and elasticity to the skin. The heat from the focused radiofrequency energy causes a controlled injury to the skin's deep layers, triggering a natural healing response. This response involves the production of new collagen and elastin fibres, which help to rebuild the skin's structure and improve its elasticity over time

The heat generated by the radiofrequency energy also helps to stimulate the activity of fibroblasts, the cells responsible for producing collagen and other connective tissue fibres. The heat triggers the fibroblasts to produce more collagen and elastin fibres, and to release growth factors that stimulate the production of new cells. The production of new collagen and elastin fibres is a gradual process that takes several months to become visible. As the new collagen fibres start to form, they create a denser and more organised network of fibres that replace the old and damaged collagen fibres. This state-of-the-art treatment stimulates new collagen production to strengthen the tightening of the skin for up to 3 years, produces very minimal to almost zero patient downtime, and can be used to treat on most areas of the body such as arms, thighs, abdomen and buttock other than eyes, face and neck
