As you age, your skin loses its elasticity. This can result in sagging skin around the chin. The loose skin is unflattering and can affect your self-esteem. Many people associate extra fat under the chin with being overweight, but even skinny people can have a double chin. If the area between your neck and jaw doesn't have a sharp angle, you have an increased chance of getting a double chin. Instead of resorting to surgery to eliminate the extra skin, adjust your lifestyle to get rid of it.

Eat healthful foods. Avoid high-calorie, high-fat processed foods that add pounds to your frame. Include fresh fruit and vegetables, whole grains, lean meats, low-fat dairy and unsaturated fats in your diet.

Exercise to burn calories and lose weight. Perform at least 30 minutes of aerobic exercise five days of every week, as well as two days of strength training. Go swimming, jogging or bike riding, or exercise on an elliptical machine or stair climber. Use free weights, weightlifting machines or your body weight to perform strength training exercises.

Perform neck exercises daily to help firm the skin under your chin. Sit in a chair and tilt your head all the way back so you feel the stretch in your neck. Open and close your mouth 10 times before returning to your starting position. Work your way up to completing three sets of 10 repetitions.

Stick out your tongue to help eliminate excess skin under your chin. Sit upright and open your mouth as wide as you comfortably can. Stick out your tongue as far as possible so you feel it in your throat. Hold this position for 10 counts before returning to the starting position. Repeat the exercise. Work your way up to completing three sets of 10 repetitions daily.

Correct your posture. Hold your neck long and straight to naturally emphasize the angle between your jaw line and neckline. Avoid slouching or slumping, because this makes the excess skin more obvious and stimulates fat to settle in your neck area.

Massage your neck to hydrate it and to help firm the loose skin. Apply a skin-firming moisturizer or essential oil, such as lavender or jojoba oil, to your neck. Make upward strokes with your hands from the collarbone to the chin. Use your fingertips to massage your jaw line from the chin backward to your ears. Make this massage part of your nightly bedtime routine so you don't forget it.
