How Does Ultrasound Lifting Work?
Principle of Ultrasound Anti-aging
Principle of Ultrasound Anti-aging
-Focused Ultrasound Technology
Ultrasound anti-aging mainly uses high-intensity focused ultrasound (HIFU) technology. This technology can accurately focus ultrasound energy at a specific depth of the skin, generally in the dermis, fascia, etc. For example, in facial anti-aging, the focus point can act on the SMAS fascia layer (superficial musculoaponeurotic system), which is where the facial expression muscles are attached and is also a key structure for facial sag after aging.
When ultrasound energy is focused on these target areas, a thermal effect is produced. The local temperature rises rapidly, generally reaching around 60-70 degrees Celsius. This temperature is enough to cause the collagen in the area to shrink immediately, just like tightening an originally loose spring, so that the skin becomes firm in a short time, and the facial contour can be seen to have an immediate lifting effect.
-Stimulate collagen regeneration
In addition to the immediate contraction of collagen, the thermal effect also triggers the skin's wound healing response. For a period of time after thermal damage, the body will recognize that the skin tissue has been "stimulated" and, as a self-repair mechanism, it will cause fibroblasts to become active. Fibroblasts are key cells for synthesizing collagen, and they will begin to synthesize new collagen in large quantities.
These newly generated collagens will gradually replenish and replace the collagen lost due to aging, further improving the texture and elasticity of the skin. This process is not achieved overnight. Generally, within 1-3 months after treatment, as new collagen continues to be generated, the skin will continue to become tighter and smoother, and wrinkles will gradually decrease.
Precautions for ultrasound anti-aging
- Precautions before treatment
Choose a formal institution and a professional doctor
Ultrasound anti-aging is a medical beauty technology that needs to be operated by professionally trained doctors. Formal medical institutions will have qualified equipment and standardized operating procedures. When choosing, you can check the qualifications of the institution and the doctor's practice certificate to understand the doctor's experience, especially in the field of ultrasound anti-aging.
- Skin assessment
Before treatment, the doctor should conduct a comprehensive assessment of the patient's skin condition. Including skin thickness, elasticity, inflammation, allergies, etc. For example, if the skin is in an allergic period or is damaged, it is not suitable for ultrasound anti-aging treatment, and it is necessary to wait until the skin returns to normal before considering it.
- Tell the doctor about your own condition
The patient needs to tell the doctor about his or her health condition, such as whether he or she has chronic diseases such as high blood pressure, heart disease, diabetes, and whether he or she is taking certain medications (especially anticoagulants). Because these factors may affect the safety or effectiveness of the treatment. For example, patients who are taking anticoagulants may have an increased risk of bleeding during treatment.
Precautions after treatment
Skin care
The skin after treatment is more fragile and needs to be strengthened. Avoid using irritating skin care products, such as products containing alcohol, fragrances and other ingredients. You can use a mild moisturizer to keep the skin hydrated and promote skin repair. At the same time, pay attention to sun protection, because the skin after treatment is more sensitive to ultraviolet rays and is prone to pigmentation. It is recommended to use a combination of physical sunscreen (such as parasols, sun hats, etc.) and chemical sunscreen (such as sunscreen).
Avoid high temperature environment
Avoid exposing the skin to high temperature environments, such as saunas, hot springs, etc. for a period of time after treatment. Because high temperatures may aggravate skin swelling or affect collagen regeneration. It is generally recommended to avoid these activities within 1-2 weeks after treatment.
Observe skin reactions
After treatment, closely observe the skin's reactions. Mild redness, swelling, or tenderness may occur, which is normal and will generally subside naturally within a few hours to a few days. However, if blisters, severe bruising, severe pain, or signs of skin infection (such as fever, suppuration, etc.) occur, you need to contact your doctor in time for treatment.
