Body Ulthera in Korea: Lifting Loose Skin on the Abdomen, Arms and Knees

Quick answer: Body Ulthera uses micro-focused ultrasound to heat deeper layers of body skin, stimulating collagen to firm loose areas such as the abdomen, upper arms, inner thighs and above the knees. Results develop over two to six months with little downtime, and it suits mild to moderate laxity rather than large amounts of excess skin.
Common treatment areas
- Lower abdomen after pregnancy or weight change
- Upper arms
- Above the knees and inner thighs
- Buttock crease and other localised areas
How it works
Ultrasound energy is focused at set depths under the skin, creating small heated points that trigger collagen renewal. A real-time image helps the operator place energy at the intended depth.
Who is a good candidate
- Mild to moderate skin laxity
- Stable weight
- People seeking non-surgical improvement
Significant excess skin is often better addressed surgically.
The experience and downtime
Sessions vary with area size. Discomfort is felt as deep heat, and pain relief or numbing is commonly offered. Mild redness, swelling or tenderness can last a few days, and occasional bruising may occur.
Results
Firmness improves gradually as collagen rebuilds, usually assessed around three to six months. Combining with muscle-toning or skin-quality treatments is common.
Frequently asked questions
Does it reduce fat?
Its main purpose is tightening, not significant fat reduction.
How often is it repeated?
Often once, with maintenance considered after about a year.
Key takeaways
- Targets mild to moderate body skin laxity.
- Results build over months.
- Not a substitute for surgery when excess skin is significant.
