I had HIFU a few times and in different salons, I know the technique and technology so I knew what to expect. Unfortunately the treatment was far below the standards I've experienced so far, the machine was applied at random across the face, which defeats the purpose of the treatment. The gel was applied uneavenly and had to ask for more of it to minimise discomfort. The treatment focused on the lower face, and very little on the temples and side forehead. Overall it lasted less than 20 mi
