What is a Fat Dissolving Injections?

Fat dissolving injections use a solution (such as deoxycholic acid, Aqualyx, or Lemon Bottle) to break down small, stubborn pockets of fat that resist diet and exercise. They are most common under the chin and along the jawline, and are also used on the abdomen, flanks, and other small areas.

A series of small injections is placed into the fat. Expect swelling and tenderness for several days to a week; the fat clears gradually over 6 to 8 weeks, and most areas need 2 to 4 sessions for a visible result.

Not every "fat dissolving" product is FDA-approved — Kybella (deoxycholic acid) is the FDA-approved option for the under-chin area, while others are used off-label. Ask exactly which product your provider uses, whether it is FDA-approved, and how many sessions your area will realistically need.

How much does a Fat Dissolving Injections cost?

Fat dissolving injections nationally typically run $600 to $1,200 per session, and most areas need 2 to 4 sessions. Your total depends on the product used, the size of the area, and how many sessions it takes — ask for the full-course estimate, not just the price of one visit.

What to ask your provider

Frequently asked questions

How much do fat dissolving injections cost?
Fat dissolving injections across the US typically cost $600 to $1,200 per session, and most areas need 2 to 4 sessions — so budget for the full course, not a single visit. The product and area size drive the price.
What is the difference between Kybella, Aqualyx, and Lemon Bottle?
Kybella (deoxycholic acid) is the FDA-approved injection for under-chin fat across the US. Aqualyx and Lemon Bottle are other fat-dissolving solutions used more widely abroad and sometimes off-label here. Ask your provider exactly which one they use and its approval status.
How many sessions do fat dissolving injections take?
Most areas need 2 to 4 sessions spaced about a month apart. The fat clears gradually over 6 to 8 weeks after each session, so results build over several months.
Are fat dissolving injections permanent?
The fat cells that are destroyed do not come back, but remaining fat cells can still enlarge with weight gain — so results last best with a stable weight. It works only on small, pinchable pockets, not overall weight loss.
Do fat dissolving injections work on loose skin?
No — they dissolve fat, not skin. If your concern is loose or sagging skin rather than a fat pocket, a tightening treatment is a better fit. A provider should confirm you are treating fat before recommending injections.
