Introduction
Skin laxity commonly occurs due to the following reasons:
- Various forms of dieting, long-distance running, or excessive weight loss, all of which can lead to loss of skin elasticity and laxity. It is recommended to lose weight primarily through exercise combined with controlled caloric intake—emphasizing physical activity and aiming for gradual, sustainable weight loss.
- Prolonged exposure to ultraviolet (UV) radiation generates excessive free radicals within the skin. These free radicals oxidize skin components, accelerating skin aging, resulting in laxity and diminished elasticity.
Many people notice that, despite their best efforts to care for their skin, it still becomes loose and saggy. Why does this happen—and how can it be improved? The details are as follows:
① Natural Aging
After age 25, women experience a gradual decline in collagen production, reduced metabolic activity, and progressive degeneration of the fibrous structures between skin cells—leading to diminished skin elasticity and age-related laxity.
Solution: Consume more fresh fruits, vegetables, and foods rich in collagen to supply natural nutrients that help combat skin aging and laxity. Maintain a regular sleep schedule, avoid staying up late, and engage in consistent physical exercise; aerobic activities, in particular, enhance metabolism and facilitate toxin elimination.
② Excessive or Rapid Weight Loss
Weight loss should be a gradual, sustainable process. However, many individuals embark on crash diets or intense exercise regimens—such as extreme calorie restriction or prolonged running—in hopes of rapid weight loss. While body weight may decrease quickly, the skin often loses its elasticity and becomes loose.
Solution: Prioritize exercise over strict caloric restriction when losing weight. Aim for slow, steady weight loss—no more than 10 pounds (approximately 4.5 kg) per month—to allow the body time to adapt safely.
③ Ultraviolet (UV) Radiation Exposure
Prolonged UV exposure generates excessive free radicals within the skin. These free radicals oxidize skin components, accelerating aging and resulting in loss of elasticity and skin laxity. Chronic, excessive sun exposure can cause photoaging—a form of premature skin aging induced by UV damage.
Solution: Apply broad-spectrum, high-SPF sunscreen before going outdoors. Opt for antioxidant-enriched sunscreens to help neutralize free radicals and protect against oxidative damage.
