HIFU, or High-Intensity Focused Ultrasound, is a non-invasive treatment. It gently boosts collagen deep in your skin. It lifts, firms, and smooths the face without any cuts. This naturally and subtly helps to refine your facial shape.
The treatment works by creating tiny, controlled heat spots. These spots encourage new collagen to grow. Over 8–12 weeks, your skin will gradually tighten. This produces clear but natural-looking results.
A 2024 review in dermatology reported strong evidence. It showed that HIFU can increase collagen density by up to 25%. This makes it a reliable choice for skin that is mildly or moderately loose. (PMC)
