Collagen and elastin are two substances within your skin that help to keep its structure firm. However, skin on the face and/or body may start to loosen and sag, due to a number of possible causes.
- Age. With the passing years, our skin’s collagen and elastin production naturally declines. The skin loses its natural elasticity.
- Lifestyle. Smoking and sun exposure can ‘prematurely age’ your skin and cause sagging. Fine lines and wrinkles can appear in dry, sun damaged, dry skin. Over time, these can lead to sagginess.
- Weight Loss. Extreme or rapid weight loss may also give you saggy skin. Skin that sags as a result of weight loss may become firmer if you practice moisturizing and exfoliating regimens regularly over one to two years.
- Genetics. Your genetic heritage may predispose the skin to sag on certain parts of your body.
- Lack of muscle tone. The underlying muscles that support your skin gradually weaken as you age. As a result, fat may accumulate in ‘baggy’ areas. When people lose weight primarily by dieting, without exercising, their skin may sag.
- Fluid retention. This can puff up the tissues of the skin, stretching them and causing the formation of saggy skin.
Slower skin recycling. As we age, our skin gradually loses its ability to shed dead skin cells. This, too, can contribute to skin-sag.
