HIFU (High-Intensity Focused Ultrasound) is a non-invasive treatment designed to lift, firm and tighten the skin without surgery. By delivering focused ultrasound energy deep into the skin, HIFU stimulates the body’s natural collagen production, helping to improve skin firmness, reduce the appearance of fine lines and create a more defined, youthful-looking appearance. It is a popular treatment for the face, jawline and neck, with results developing gradually over the weeks following treatment.
