I'm an 18 year old guy. I have a double chin, but my body is almost skinny. How can I lose my face fat?

Hello and thank-you for your question.We have some very exciting new technologies for non-invasive tightening of the Neck. Renuvion powered by J-Plasma (Cool Helium Plasma) along with liposuction can produce dramatic improvement in skin laxity and fat reduction.  This technology has produced beautiful results for correction of a turkey neck without the scar required with a traditional neck lift.  Ultherapy and other non invasive treatments for fat reduction A (Coolsculpting, Kybella) would also be an option.Price would depend on geographical location.I would recommend an in person consultation with a board-certified plastic surgeon well versed in all aspects of facial rejuvenation.Best, Andrew Lyos MD FACS

You have a lot of great options for getting rid of your genetic double chin. You can choose Kybella’s deoxycholic acid, which melts fat away; CoolMini, which freezes and destroys fat cells; and facial liposuction, a surgical procedure that uses tiny straws to vacuum away the fat. Liposuction is fastest, but has a few days of recovery. CoolMini has minimal downtime. Kybella may give you a little more swelling. It may take a few treatments and a few months before you see your results. Consulting a board-certified dermatologist who offers all these treatments will help you decide which technique to choose.

Patients with normal weight that has excess of adipose tissue underneath the chin ( double chin) usually could benefit from chin liposuction. 
Chin liposuction is a plastic surgery procedure that permanently removes the excess of fat under the chin that usually runs in the families and/ or is resistant to decrease in size with diet and exercise. In my practice I routinely perform chin lipo under local anesthesia. 

I find that VASER liposuction in combination with ThermiRF are best for contouring the chin in those who are candidates but Kybella can be used as an alternative and gets better results when combined with thermage/ultherapy/exilis or coolsculpting. I recommend getting a formal evaluation with an expert. Best, Dr. Emer

Neck liposuction is a great option for patients with good skin elasticity and excess fat in the neck and around the jawline. This will remove excess fat and stimulate the skin to contract over time which will improve angulation and definition along the jawline. I recommend seeing an expert for a consultation who can go over this procedure to determine if it will achieve your desired results and the cost of the procedure. I hope this helps!

Kybella would be an excellent option for you to focus solely on the area of concern; namely your submental area.  This is a simple office based treatment with permanent results.

Non-surgical options to improve fat under the chin would include Kybella injections and CoolSculpting.  An examination or photographs of you would be needed to determine if you might be a good candidate for treatment.
