Hello,The most effective way to regain the lost contours of your face with age is through tightening your skin. With the advent of high-tech aesthetic devices, it's possible to give your skin this youthful touch as an alternative to surgery: Fast, easy, painless, and long-lasting!Considering collagen as the cornerstone for skin tightness, it's inevitable that sun exposure accelerates the skin's aging process. Without collagen, the skin sags and wrinkles. While escaping aging is impossible, there are practices to slow down the process: Today's skin tightening treatments, from ultrasound to radiofrequency and laser lights at various wavelengths, employ different energy sources and technologies, all aiming to increase collagen and elastin production in the skin. Like all other organs in the body, the skin ages. There isn't a single factor causing facial aging. The aging process manifests due to a combination of different factors like genetic inheritance and environmental influences. The loss of elasticity, fine lines, and wrinkles we observe in our skin over the years mostly occur due to sun exposure and atmospheric pollution. Sun rays trigger an enzyme that reduces the amount of collagen and elastin, the building blocks of the skin. Excessive sun exposure also damages our DNA, activating certain genes in the skin, leading to abnormal functioning. Thermage FLX is an otherworldly technology. No radiofrequency system, excluding operating room procedures, has been able to reach 80°C beneath the skin until now. We've used J-plasma under anesthesia in the operating room to reach high temperatures before Thermage FLX. However, Thermage FLX has achieved a miracle in terms of "non-surgical facelifts." Without anesthesia, solely with a cold-tip applicator and vibration technology, we effortlessly perform an extremely effective aesthetic procedure without disrupting daily life. Since Thermage CPT only reaches 56°C beneath the skin and its applicator is solely for cooling, it naturally falls behind in comfort and effectiveness compared to Thermage FLX, which can reach 80°C. Moreover, with its applicators only reaching 3mm, the scope of depth is naturally limited, resulting in a much more superficial effect. Smaller applicators naturally create smaller cones on the surface. In radiofrequency technology, it always spreads as an inverted cone, hence the size and depth of the applicator are crucial in terms of the strength and permanence of the effect. Skin irregularities, numbness, blisters, and other side effects you mentioned are not an issue with CPT or FLX. Depending on the radiofrequency power, there might be slight irritation at specific points such as shot marks, peeling, or redness within a few days. Regardless of CPT or FLX, a significant difference is observed after application, progressing with daily skin rejuvenation and continuing for 6 months, ultimately lasting for many years at the end of the 6-month period
