Hello, Thermage FLX has gained popularity in recent years and is the most effective device globally for jaw contouring. It is the only monopolar radiofrequency system capable of heating the skin to 80 degrees Celsius beneath the surface. It's the ideal choice for the first application in facial lifting and skin rejuvenation, creating a V-shaped appearance. Thermage FLX does not have the ability to break down fat in the chin or other body areas. Therefore, when such specific situations arise, complementing with Ulthera for that region is the most suitable option. Depending on the thickness of the fat tissue, Ulthera offers different ultrasound heads that penetrate deeper. When there's fluctuation in jaw contouring and sagging in the cheeks, fillers should not be preferred. Treatment methods that primarily tighten the skin should be applied first. This is because if the skin isn't tightened, the fillers will succumb to gravity, causing the face to appear rounder and the neck shorter than it actually is. Hence, the primary focus should be correcting the loss of elasticity in the skin. Thermage FLX features a cold tip and vibration system, ensuring no damage to the skin and no impact on social life. It rejuvenates and renews the skin, with effects lasting a considerable amount of time. Though the sensation varies from person to person, it generally feels like a rubber band snap—painless and mild. As it isn't a surgical facelift treatment, it doesn't involve surgical complications, making it highly reliable with natural-looking results. In the Thermage FLX treatment protocol, additional focused ultrasound methods like Ulthera for excess fat, additional lasers for skin spots or acne scars, and mesotherapeutic injections may be recommended. Thermage FLX is a recommended, reliable, and high-standard treatment protocol for anyone seeking to maintain facial expressions and prevent drastic changes in their appearance.
