Skin laxity is a common concern that occurs as a result of various factors, both intrinsic and extrinsic. The natural aging process leads to a decrease in collagen and elastin production, which are essential proteins that support the skin's structure and elasticity. As these proteins diminish over time, the skin loses its firmness and begins to sag.

Exposure to environmental factors like UV radiation, pollution, and smoking can contribute to the breakdown of collagen and elastin fibres, accelerating the development of sagging skin. The harmful effects of free radicals generated by these external aggressors can damage the skin's supportive structures and lead to premature sagging.

Genetics also play a role in the predisposition to skin laxity, as some individuals may have a genetic tendency to lose skin elasticity more rapidly than others. Additionally, fluctuations in weight, poor nutrition, dehydration, and unhealthy lifestyle habits can further exacerbate the sagging of the skin.
