The number of High-Intensity Focused Ultrasound (HIFU) sessions you need will be determined based on several factors, including your specific skin concerns and treatment goals. Multiple sessions are recommended to achieve optimal results.   For most people, a series of 2 to 4 HIFU sessions spaced about 4 to 6 weeks apart is recommended. This allows for sufficient time for your skin to heal and for the collagen-building process to take effect. During each HIFU session, ultrasound energy stimulates collagen production deep within the skin, resulting in skin tightening and rejuvenation. Over time, the effects of HIFU continue to appear as the newly produced collagen gradually lifts and firms the skin.   To determine the ideal number of sessions for your specific needs, consult a qualified HIFU provider. Our team will assess your skin, discuss your goals, and develop a personalized treatment strategy to achieve your desired results.
