06月16 When should 4D HIFU be used for skin tightening?
The visible outer layer on the skin surface called the epidermis acts as a protective barrier. Underneath that is the elastin and collagen-rich tissue called the dermis. The subcutaneous layer below that is the fat layer, with a web of collagen fibers running through it. Aging, weight fluctuations, and sun exposure contribute to the break down of the elastic tissue and collagen in these skin layers. This causes the skin to sag, and wrinkles, jowls and “bags” form.
Naturally, treatments that work on just the surface can’t do anything to restore the collagen or elastic tissue in the under-layer, or the deep dermis of your skin. Fortunately, there are noninvasive treatments that can help many patients postpone invasive surgical tightening of the skin.
Description of treatments
A microfocused ultrasound treatment breaks up fat by causing non-selective thermal injury underneath the skin, bypassing the surface. A radiofrequency treatment emits heat energy to stimulate collagen production and kill fat cells. These skin-bypassing technologies can be effective with a wide range of patients, including those with darker color skin that may experience discoloration with a laser.
For complete patient satisfaction, many of the device treatments are part of a total rejuvenation program, which typically includes hyaluronic acid and other fillers to lift the face and neuromodulators to help with dynamic wrinkles, those created by muscle movement. With the device treatments, the process of demolishing old collagen and reconstructing new collagen can take several months. Using these injectables in combination with the device treatment will provide a more satisfying and immediate result during the energy-based remodeling process. Volume restoration with fillers—an injectable gel formula—focus on treating fine lines and wrinkles by restoring hyaluronic acid to the face. Results can last up to two years, depending on the area of the body.
What outcome should patients expect?
