Connective tissues maintain our skin’s elasticity, resilience, and tone. However, with age, the production of collagen and elastin (connective tissues) reduces. This makes the skin loose and wrinkled as its elasticity and strength are reduced. In addition to this, the underlying muscles become weak, making the skin less taut (for example, facial muscles).
Sun exposure is one of the primary causes of loose skin, particularly premature skin sagging. While it’s fun to enjoy the sun and to get that perfect body tanning, the UV rays tend to penetrate your skin, causing damage to the connective tissue. With continued exposure to the sun, your skin becomes loose and wrinkled as the connective tissues continue to break down.
If you lose a lot of weight over a short period, either through exercise and dieting or through surgery, you may be left with excess skin that sags. This can be attributed to the fact that your skin grows/stretches as you gain weight, but when you lose weight, it remains too stretched out for the snapback effect to occur.
Smoking produces toxins that affect the skin in many ways. It’s one of the main factors attributed to premature aging of the skin. The toxins produced during smoking affect the delivery of oxygen and vital nutrients required to replenish the skin for a healthy, smooth, and well-toned skin. This causes the skin to lose its elasticity, become dry, and wrinkled.
