4.0DJM AU-01 Ultra One

Quick tip if you're ordering: grab a bottle of ultrasound gel from the pharmacy before it arrives since it doesn't come with one! Once you fill the little well on the probe with gel, it glides super smoothly. I ended up getting the bundle with the extra probe for $62.50 so my mom could use her own head when she visits. I'm three sessions in and the little pouching along my jawline has definitely tightened up. Zero regrets.

I usually save my device routines for the evening because they leave my face flushed, but I can actually use this one in the morning. After a session, I applied my skincare and foundation and headed to work. My jawline looked great, and no one could tell I’d just used a device. For me, it’s been worth the investment.

The price tag made me a bit skeptical, especially since I dreaded the pain. I honestly kept checking if it was even working because there is literally zero sensation. But I did half my face first to test it, and the visible tightness along my jawline was undeniable. Very impressed so far.

I was a bit nervous about doing this at home, but the app makes it incredibly easy. No annoying "AI" gimmicks, just clear visual diagrams showing exactly where to move the device and what areas to avoid. I love that I can manually set the energy level so I'm always completely in control. My jawline is already looking sharper. Totally worth it.

I have zero pain tolerance, so the thought of thermal lifting terrified me. But this? It just feels like a warm, relaxing massage on my face. The app is what really sold me though—it walks you through exactly what to do step-by-step, so you don't have to guess. Finally, a beauty tech piece that doesn't feel like a chore.

I was so tired of dropping $2,000 at the dermatologist every year for lifting treatments. I hesitated to spend $695 on an at-home device, but this actually works. It doesn't just sit on the skin; you can feel it working deep down. After a month, my husband even asked if I lost weight because my jawline looks so much sharper. It’s an absolute staple in my routine now.

I own a drawer full of beauty devices that promised the world and delivered nothing. This is the first one that actually grips the deep tissue and lifts from within. I noticed the marionette lines around my mouth softening after just three weeks. It’s a serious piece of clinical technology, not a toy.

Yes, my facial contours are sharper, but what surprised me most is the overall vitality of my skin. It has this 'lit-from-within' glow that I haven't seen in years. It truly feels like it’s regenerating collagen from the deepest layer.

As I approached 45, I noticed my jawline softening. Creams did nothing. This device actually targets the deep layers. Four weeks in, my lower face is visibly sculpted and the puffiness under my chin is gone. Worth every penny.

I used to get professional HIFU twice a year. The DJM-AU01 paid for itself after my first week of using it. The deep lifting sensation is exactly the same, but without the pain or the $2,000 bill. An absolute game-changer for my jawline.
