Sagging Skin

Sagging skin is the visible loosening of facial or body skin that occurs when collagen and elastin break down faster than the body replaces them, often compounded by gravity over time. It’s one of the most common concerns HIFU is used to address, because the mechanism directly targets the underlying cause rather than just the symptom: focused ultrasound energy heats the dermis and connective tissue at a chosen depth, producing an initial, immediate tightening from collagen contraction, followed by a more gradual firming as new collagen forms over the following weeks and months. The neck and jawline are common areas of concern (sometimes referred to informally as “turkey neck”), along with the cheeks and under-eye area, though the degree of improvement depends on how advanced the laxity is — more significant, long-standing sagging generally needs more sessions and produces more modest results than mild-to-moderate cases.
