HIFU uses focused ultrasonic waves to reach deeper layers of the skin, stimulating elastin production for firmer, smoother skin. The treatment encourages collagen regeneration, reducing wrinkles and improving texture. It’s ideal for individuals over 30 with mild to moderate skin sagging. However, it may not be suitable for those with severe skin issues or certain skin conditions. Multiple sessions may be needed for more noticeable results, especially for individuals with significant aging or skin damage.
