Double chin fat is one of those stubborn areas where diet and exercise don't move the needle. The fat under the chin, technically called submental fat, sits in a layer that responds poorly to caloric deficit alone. People who are otherwise at a healthy weight often carry it for years without any change.
CoolSculpting® chin treatment targets that layer directly. It freezes the fat cells without surgery or downtime, and the body clears them over the weeks that follow. This article covers what the treatment involves, what before-and-after results look like, the swelling timeline, and what it costs at New Day Medspa in Jacksonville.

How CoolSculpting® chin treatment works
The CoolMini is the applicator designed specifically for the submental area. It's smaller than standard CoolSculpting® applicators and fits the contour under the chin. During treatment, it draws the chin tissue into the cup and holds it at a controlled cold temperature, targeting the fat cells underneath without affecting skin or surrounding tissue.
Fat cells are more vulnerable to cold than other cell types. At the target temperature, fat cells begin a natural cell-death process called cryoapoptosis. Over the following weeks, the body's lymphatic system gradually clears those cells. The skin above is not damaged. The area simply slims as the fat volume reduces.
One treatment cycle runs 35 to 45 minutes. Patients sit or recline during the session. You may feel a pulling, cold sensation in the first few minutes that fades as the area numbs. Most people read or use their phone for the duration.
CoolSculpting chin before and after: what results actually look like
Results from CoolSculpting® chin fat treatment don't appear immediately. The clearance process takes weeks, which surprises some patients who expect change quickly.
A 2016 pivotal study in Lasers in Surgery and Medicine enrolled 60 patients treated with the CoolMini applicator at -10°C for 60 minutes. Blinded physicians correctly identified pre-treatment photos 91% of the time at the 12-week follow-up, exceeding the 80% primary endpoint. 77% of patients reported visible fat reduction, and 83% were satisfied with the outcome.

What the timeline looks like week by week:
Results vary by starting volume. Patients with a moderate fat layer often see a clear improvement from a single session. Patients with more submental fat may benefit from two sessions for a complete result.
What the swelling looks like and how long it lasts
This is what most patients want to know before booking.
Swelling after CoolSculpting® chin treatment is normal. It's part of the inflammatory response triggered by cryoapoptosis, the same process that produces the fat reduction. The area under the chin will look fuller and feel firm for several days to a few weeks after treatment, which can look like the opposite of improvement in the short term.
Most swelling is visible in the first week, then reduces through week two. By week three, the area usually looks roughly back to its pre-treatment appearance before the actual slimming begins. Temporary numbness is common and can last a few weeks as sensation returns to the treated tissue.
Bruising is possible but less common in the chin area than in larger treatment zones. Tenderness when pressing on the area is typical and may last two to four weeks.
There's no medical downtime. Patients leave the same day and return to normal activity immediately. The restriction is avoiding anything that sharply increases circulation to the face (intense heat, vigorous cardio) in the first 24 hours.
Expert tip: Patients often book a consultation right after noticing their chin looks fuller from the post-treatment swelling and want to know if something went wrong. Nothing has. The swelling is the treatment working. The 8- to 12-week mark is when to evaluate whether a second session is needed. Comparing post-treatment photos to pre-treatment photos, rather than to the swollen interim, gives a clearer read on actual progress.

What does CoolSculpting® for the chin cost in Jacksonville?
At New Day Medspa, CoolSculpting® starts at $399 per treatment. The chin is typically a single-applicator area, so one session is one treatment cycle. Patients who need two sessions to reach their goal pay per session.
These are starting rates. A complimentary consultation at New Day Medspa maps the actual submental fat volume and determines whether one or two sessions fit the patient's goals.
Financing is available through Cherry, PatientFi, Afterpay, and Klarna. CoolSculpting® is also available at $99 per month with a payment plan, which covers the chin and any additional areas treated in the same program.
Who is a good candidate for CoolSculpting® chin fat treatment?
CoolSculpting® works on fat that can be drawn into the applicator cup. For the chin, that means patients with a visible, pinchable layer of submental fat that persists regardless of weight or exercise.
It's not a weight-loss treatment, and it's not suited for skin laxity. If the primary concern under the chin is loose skin rather than fat, CoolSculpting® does not fix that. A provider assessment at consultation determines which component, fat or skin, is responsible for the appearance, and whether CoolSculpting® is the right fit.
Good candidates are typically at or near a stable weight, bothered by submental fat that hasn't responded to lifestyle changes, and not expecting a surgical-level transformation from a single non-surgical session.
CoolSculpting® chin vs. Kybella: how they compare
Both are non-surgical options for submental fat. They differ in how they work and what the experience is like.
Neither option removes skin. Patients with notable skin laxity under the chin often find that both treatments expose the loose skin more visibly as the fat reduces, which is worth discussing at consultation.
New Day Medspa offers CoolSculpting® for the chin. Patients specifically asking about Kybella should ask about all available options at their consultation.
