Loose skin can develop for many reasons. One of the most common causes is quick weight loss, which can cause your body mass to decrease and force the skin to play catch-up. Loose skin can also develop gradually as your body ages and the skin loses its nutrients, particularly collagen and elastin, which keep your skin pliable and able to tighten on its own. There are things you can do to your skin to tighten it up for a more healthy and fit look.
Drink Water
Skin can appear loose or sagging if it is dehydrated. The skin requires ample hydration to perform process key to its health, including the production of collagen. You may be able to see significant improvement in your skin's tightness just by drinking water--at least eight glasses a day is recommended. Even if you don't see improvements, you will still benefit from the water over time, as you employ other treatments to tighten your skin.
Moisturize the Skin
Moisturizing helps to lock moisture into the skin to keep it healthy and soft. It will diminish the appearance of some wrinkles in your skin and can help improve its elasticity, which can enable it to retract back to the desired tightness. You should moisturize your body at least twice daily, including right before going to bed.
Manage Your Weight Loss
If you are losing weight at a rapid pace, you may be doing more harm than good. When the body loses mass faster than the skin can keep up, it creates looseness because the skin runs out of muscle fibers to attach itself to and cannot retract itself fast enough. This looseness can become permanent, resulting in stretch marks if it is not treated. If you are developing loose skin due to a diet, curb your weight loss and maintain your current weight. This will allow your skin time to catch up. You can resume the diet later--at a slower rate--once the skin catches up.
Broad Spectrum Treatments
According to ScienceDaily.com, new developments in light technology have created ways for the skin to be tightened through a medical procedure. Similar to the way laser treatments are employed, broad spectrum light treatments use a broad band of infrared light to heat the middle layers of your skin, triggering collagen creation. This improves your skin's elasticity and allows itself to tighten around the structures of your body, effectively toning your skin without any work done on your part. The light treatments applied to small or large areas of skin.
