Introduction
This condition is commonly caused by the following factors:
- Excessive weight loss, various forms of restrictive dieting, or prolonged long-distance running—leading to loose, inelastic skin. It is recommended to lose weight through regular exercise and controlled caloric intake.
- Ultraviolet (UV) radiation: Prolonged UV exposure generates excessive free radicals within the skin, accelerating skin aging, laxity, and loss of elasticity. It is advisable to apply a high-SPF sunscreen before going outdoors.
Many people notice that, despite diligent skincare, their skin still becomes lax. Why does this happen—and how can it be improved? Details are outlined below:
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 cells—leading to diminished skin elasticity and the onset of sagging.
Solution: Consume more fresh fruits and vegetables, as well as foods rich in collagen, to supply natural nutrients that help combat skin aging and laxity. Maintain regular sleep patterns, avoid staying up late, and engage in consistent physical exercise—particularly aerobic activities—which enhance metabolism and facilitate toxin elimination.
② Excessive Weight Loss
Weight loss should be a gradual, sustainable process. However, many individuals embark on rapid weight-loss efforts—driven by impulsive motivation—hoping to shed pounds dramatically in a short time. Extreme dieting and prolonged running often result in significant weight reduction but also cause skin laxity and loss of elasticity.
Solution: Achieve weight loss primarily through exercise, supplemented by moderate caloric restriction. Aim for slow, steady progress—ideally no more than 5 kg (≈11 lbs) per month—to allow the body 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 causing laxity and loss of elasticity. Chronic, intense sun exposure can damage the skin and lead to photoaging.
Solution: Apply broad-spectrum, high-SPF sunscreen before going outdoors. Opt for antioxidant-enriched sunscreens to neutralize free radicals and mitigate oxidative damage.
