A non-invasive and painless alternative to facelifts, high-intensity focused ultrasound (HIFU) is a new type of cosmetic tightening therapy. Firmer skin results from a procedure that uses ultrasonic waves to encourage collagen formation.
The FDA approved brow lifts with HIFU in 2009. Decolletage lines and wrinkles were also authorized in 2014 for treatment by the FDA. The common question is, how many days after doing HIFU, face is swollen? (หลัง ทำ HIFU หน้า บวม กี่ วัน, which is the term in Thai).
Several modest clinical trials have shown that HIFU is safe and effective for elevating the face and reducing wrinkles. Within a few months of treatment, patients began seeing effects without surgery risks.
Aside from body sculpting and rejuvenation, HIFU can also be used to tighten skin and neck. However, these are “off-label” uses, meaning the FDA has not yet approved them.
Facial High-Intensity Focused Ultrasound.
Focused ultrasonic energy is utilized in HIFU to target the skin’s subsurface layers. Ultrasound energy rapidly raises the temperature of the tissue. Te targeted cells are heated to cause damage. This causes damage and leads to collagen production, a protein that gives skin its structural integrity and strength.
As collagen production rises, the skin becomes tighter, firmer, and less wrinkled. A specific tissue spot is targeted by high-frequency ultrasonic beams, avoiding damage to the upper layers of skin and neighboring tissues. Are you wondering how many days after doing HIFU, face is swollen? The best part is that the swelling goes away in a few hours.
It is not recommended for those over 50 who have severe skin laxity or excessively droopy neck skin.
These conditions, as well as those associated with metallic implants or open skin lesions in the treatment area, make HIFU contraindicated.
High-Intensity Focused Ultrasound: A Promising Technology
There has been a rise in the popularity of HIFU and other non-surgical facelift options. The aesthetic benefits of HIFU include:
- Eliminating wrinkles and tightening up sagging skin around the neck (sometimes called turkey neck)
- Cheeks, brows, and eyelids are raised
- Adding definition to the jawline
- The neck and décolletage skin is smoothed and strengthened.
HIFU dramatically improved skin elasticity in the cheeks, lower belly, and thighs after 12 weeks of treatment, according to a 2017 study that involved 32 Korean participants. To answer, how many days after doing HIFU, face is swollen? The swelling recedes in a few hours post-treatment. In a more extensive study of 93 patients, 66% reported an improvement in their facial and neck look after 90 days of HIFU treatment.
