Results from cavitation and similar non-invasive body contouring treatments are gradual, not immediate. Some people notice a slight change after 1–3 sessions (temporary inch reduction or reduced bloating appearance) Visible, consistent results usually appear after 4–8 sessions Best results often show up over 2–6 weeks, especially when combined with: good hydration light exercise balanced diet Key point: Fat reduction happens gradually as your body naturally processes the broken-down fat cells, so results build over time not overnight.
