Skin laxity refers to skin that has lost its firmness and elasticity, resulting in a looser, less defined appearance. It most commonly affects the face, neck, jawline, upper arms and abdomen, and tends to become more noticeable from the mid-thirties onwards as collagen and elastin production naturally declines.

Collagen and elastin are the structural proteins that keep skin firm, bouncy and well-supported. As their levels decrease with age, the skin becomes thinner and less able to hold its shape. Sun damage, significant weight changes, genetics and lifestyle factors can all accelerate this process.

Non-surgical treatments that stimulate new collagen production can improve firmness and definition over time. Results are gradual but progressive, and the degree of improvement depends on the starting point, the treatment used and individual factors.
