Skin Laxity

Skin laxity describes how loose or firm the skin is, driven mainly by the balance between collagen and elastin production and breakdown, with gravity and sun exposure as contributing factors over time. As collagen density falls and elastin fibres lose their elasticity, skin becomes less able to spring back into place, which shows up as sagging, drooping, or a loss of sharp facial contours — most visibly around the jawline, neck, and under the eyes. HIFU is designed to improve laxity by stimulating the skin's own dermal repair mechanisms: focused ultrasound energy heats the targeted layer enough to trigger new collagen and elastin formation, gradually restoring some of the structural support that gives skin its firmness. The degree of improvement depends heavily on how advanced the laxity is — mild-to-moderate laxity generally responds better than severe, long-standing sagging, which may need more sessions and produce more modest results.
