Underarm Fat Reduction in Seoul

Underarm Fat Reduction explained

Underarm fat is a small pocket of fat between the upper arm and the side of the chest, often seen above a bra strap or in sleeveless tops. Non-surgical treatments reduce the number or size of fat cells in this area. Some bulges are actually extra breast tissue (accessory breast, 부유방), which does not respond to fat treatments and needs a doctor's check.

How Underarm Fat Reduction works

Fat-dissolving injections are placed into the fat layer to break down fat cell membranes, and the body clears the fat over weeks. Onda uses focused microwave energy to heat and damage fat cells, while cryolipolysis uses controlled cooling to trigger fat cell death. For larger amounts of fat or extra breast tissue, liposuction or surgery may be advised instead.
