As you get older, the skin on your body can start to sag. One problem area is the neck. The natural aging process along with sun exposure and damage causes collagen to break down and cause wrinkles and drooping skin. Many people seek out natural remedies and vitamins to firm up neck skin and regain a more youthful appearance.

One way to combat sagging neck skin at home is to moisturize regularly. Having properly hydrated skin directly relates to your skin's elasticity, according to iFit and Healthy. You can apply a topical cream to your neck sweeping in an upward motion toward the chin after cleansing your face to maintain a firmer look. You should also make an effort to stay hydrated from within by drinking at least eight glasses of water a day.

Exercising is another natural way to reduce sagging skin along the neck. While getting plenty of cardiovascular exercise is essential for staying healthy, you also need to build muscle mass. Bulking up can fill in the gap between your muscles and the sagging skin, making it appear more taut and youthful, according to iFit and Healthy.

Vitamins are also essential for healthy skin. Vitamin C is vital for the production of collagen, states Oregon State University, and aids in protecting your skin from sun damage, another major cause of elasticity loss. Get vitamin C from citrus fruits and broccoli. Vitamin E is another essential vitamin for firm skin, according to Southwestern Medical Center. It plays a major role in collagen production, makes your skin softer and can aid in wound healing. Vitamin E is found in foods like avocados, vegetable oil and nuts.

One of the most important vitamins for the skin is vitamin A.

Opt for colorful fruits and veggies to get your vitamin A fill and consider a topical retinoid to firm up sagging neck skin directly.
