I've been using the HIFU FacialDefy 4.0 for a little over a month now, and I’m honestly impressed with the gradual yet visible improvements in my skin. I’m 48 years old, and my main concerns were sagging along the jawline and slight puffiness around my eyes. After 4 treatments (1 per week), I noticed that my skin feels firmer, my cheekbones appear slightly more lifted, and my jawline looks more defined—especially in photos.

What I appreciate most is that the device feels professional-grade, but it's easy enough for home use once you get used to the intensity settings. The instructions were clear, and I followed the recommended gel and time per area. No redness or discomfort afterward—just a warm feeling during use.

One thing to keep in mind: it’s not a miracle machine. The effects are subtle and build up over time, which is actually more natural-looking. I recommend taking before and after photos to really track your progress. Overall, I’m very satisfied and will continue using it as part of my skincare routine.
