Have you heard of ultrasound knife facial contouring? When it comes to facial slimming, many first think of radiofrequency skin tightening or Botox. However, with the rise of minimally invasive procedures, new methods for facial contouring and wrinkle reduction have emerged—namely, the ultrasound knife. But is it truly a "knife"?Actually, no. The ultrasound knife is a medical device, formally known in Chinese as "High-Intensity Focused Ultrasound." It primarily utilizes the principle of high-energy focused sound waves to concentrate energy at a single point, rapidly penetrating the epidermis, fat layer, and fascia layer.
What is the Ultrasound Knife?
Is the Ultrasound Knife really a knife? Actually, no. The Ultrasound Knife is a device, formally known in Chinese as "High-Intensity Focused Ultrasound." It primarily utilizes the principle of high-energy focused sound waves to concentrate energy at a single point, rapidly penetrating the epidermis, fat layer, and fascia layer. Within the fascia layer, it creates a network of coagulation points.These coagulation points reach temperatures of 65-70 degrees Celsius. This high-temperature stimulation causes muscle tissue contraction and tightening, promoting the regeneration of collagen and elastic fibers. This helps address issues like skin laxity, aging, sagging, and dryness. For individuals with excess facial fat, the ultrasound knife can also achieve a slimming effect on the face.
So why is it called a "knife" if it isn't literally a knife?This is actually to emphasize the device's remarkable and rapid effects.
Is the Ultherapy effective?
Ultherapy can tighten skin laxity, addressing issues such as eye bags, nasolabial folds, marionette lines, double chin, drooping eyelids, and neck aging. It restores skin elasticity, firms contours, and progressively improves wrinkles, tightness, and cheek lifting in a comprehensive manner.The ultrasound knife causes no damage to the epidermis and does not compromise the skin barrier's function. It can be considered non-invasive, making it suitable even for sensitive skin.
However, the effects are not permanent. A single treatment typically lasts about two years, and with proper daily skincare, results can persist for 3-5 years.Since the treatment requires manual operation, results depend on the practitioner's skill. Seeking an experienced physician is recommended.
Are there many side effects?
Side effects are rare. The primary ones include redness and swelling. Some individuals may develop a rash due to sensitivity to the coupling agent, but this typically resolves as the skin heals naturally.A more serious complication is potential thermal damage to nerves, leading to nerve edema. However, once the edema subsides, the skin can gradually repair itself.
What precautions should be taken for ultrasound knife care?
1. Avoid using fruit acid products before and after treatment. If you have previously undergone procedures such as gold thread lifting, implant placement, or filler injections, inform your physician beforehand.
2. Ultrasound knife treatment is not recommended for pregnant women, individuals with open wounds, or those with severe acne.
3. Mild redness may appear on the skin for one to two hours after treatment. This is normal and temporary. Ensure timely hydration and moisturization, and minimize makeup application.
4. Avoid high-temperature environments and direct sun exposure after treatment.
