HIFU （High-intensity focused ultrasound）is a relatively new cosmetic treatment for skin tightening that some consider a noninvasive and painless replacement for face lifts. It uses ultrasound energy to encourage the production of collagen, which results in firmer skin.
The ultrasonic energy will be focused on a subcutaneous 1cm2 central area with 12mm diameter after being sent out from the handpiece. The ultrasonic energy will selectively break adipose cell. Thus, big adipose tissue will be broken into small particles, and eventually being excreted to the outside of the body through metabolism. The focus ultrasonic technology has stronger energy, better effect than the traditional ultrasonic fat reduction methods. Besides, the therapeutic range is more targeted because the focused ultrasound can destroy the fat without damaging other tissue.
HIFU uses focused ultrasound energy to target the layers of skin just below the surface. The ultrasound energy causes the tissue to heat up rapidly.
Once the cells in the targeted area reach a certain temperature, they experience cellular damage. While this may seem counterintuitive, the damage actually stimulates the cells to produce more collagen — a protein that provides structure to the skin.
The increase in collagen results in tighter, firmer skin. Trusted source with fewer wrinkles. Since the high-frequency ultrasound beams are focused on a specific tissue site below the skin’s surface, there’s no damage to the upper layers of the skin and adjacent issue.
HIFU may not be appropriate for everyone. In general, the procedure works best on people older than 30 with mild-to-moderate skin laxity.
People with photo damaged skin or a high degree of loose skin may need several treatments before seeing results.
Older people with more extensive photo-aging, severe skin laxity, or very saggy skin on the neck aren’t good candidates and may need surgery.
HIFU isn’t recommended for people with infections and open skin lesions at the target area, severe or cystic acne, and metallic implants in the treatment area.
HIFU treatment for face side effects
HIFU is considered very safe if performed by a trained and qualified professional.
The best part about this treatment is that you’re able to resume your normal activities immediately after you leave the provider’s office. Some slight redness or swelling may occur, but it should subside quickly. A light tingling sensation of the treated area may persist for a few weeks.
Rarely, you may experience temporary numbness or bruising, but these side effects usually go away after a few days.
