A double chin, also known as submental fullness, is a common cosmetic concern that occurs when a buildup of fat under the chin causes the area to appear full and saggy. It can be caused by a variety of factors, including:

Genetics: some people may be more prone to developing a double chin due to their genetic makeup.

Weight gain: as weight increases, the fat deposits under the chin can become more prominent.

Aging: as we age, the skin and muscles in the chin and neck area can weaken and lose elasticity, causing a double chin to appear.

Posture: poor posture can cause the muscles in the chin and neck area to weaken, leading to a double chin.

Hormonal changes: hormonal changes during pregnancy or menopause can cause a double chin.

Modern treatment options for a double chin include:

Bella: Bella is a non-surgical injectable treatment that uses a synthetic form of a naturally occurring acid to dissolve fat cells under the chin.

Liposuction: liposuction is a surgical procedure that involves removing excess fat from the chin and neck area.

Coolsculpting: cool sculpting is a non-surgical procedure that uses controlled cooling to freeze and eliminate fat cells under the chin.

Radiofrequency (rf) energy: rf energy uses heat to tighten and contour the skin under the chin.

Ultrasound therapy: ultrasound therapy uses high-frequency sound waves to stimulate collagen production and improve skin elasticity.
