4D HIFU (High-Intensity Focused Ultrasound) is primarily designed to rejuvenate and tighten the skin, making it appear more youthful and refreshed. However, like any cosmetic procedure, the results of 4D HIFU can vary depending on several factors, including the individual’s unique skin characteristics, the skill of the practitioner, and the treatment plan. In general, when performed correctly by a qualified and experienced practitioner, 4D HIFU should not make you look older.
