Product Reviews

7-Day Delivery
I was searching for the most powerful 308nm device for my clinic, and Hey Med recommended the 5000C. The MED function is incredibly helpful in determining the right dose for each client. The Kernel’s built-in systems will also help us to manage their cases. The six shade tips are also a great addition—not just for large areas, but especially for small, delicate spots like the eyebrows, eyelids, and behind the ears. I’m very satisfied with this machine and would recommend it to other professionals.

I was skeptical at first, but I’m satisfied after a few days of using it
I was skeptical at first, but I’m satisfied after a few days of using it. Ming was incredibly patient and helpful, answering all my questions—even after I received the machine. One of the best features is that this 308nm Excimer Laser basically needs no rest time. This has been a game-changer for my clinic. It lets us treat more patients each day. Would recommend!

Good to treat stubborn, small spots.
I had been searching for a machine that could effectively treat my patients' psoriasis, vitiligo, and eczema on small areas like the eyelids and eyebrows. I’m so glad we came across the KN-5000C! The tips allow me to target specific spots without affecting the surrounding healthy skin, which is a huge advantage. Since 308nm light is stronger, we can provide shorter treatment sessions while achieving quicker results with minimal side effects. It also allows us to treat more patients each day. I also feel much more confident using this device on the children in our clinic.

The package arrived in 7 days, which was fine.
Quality machine. We are really satisfied with the dose and time treatment options. These features allow us to tailor treatments to the patients' different needs. Unlike other Kernel UVB lamps, this one lets you adjust the dosage directly without having to manually calculate treatment time in seconds—a huge convenience. While it's not a cure-all, our patients have been excited to see noticeable improvements after just a few sessions. Definitely a solid choice for those considering for a powerful UVB device to expand their practice.

The 6 laser tips are very helpful
As a dermatologist, I am always looking for devices to help my patients with psoriasis, vitiligo, and eczema. Excimer Laser stands out as a more powerful option compared to other home UVB lamps. Most of my patients have noticed improvements within a month. One of its best features is the six laser tips, which allow for targeting of affected areas without exposing healthy skin. I highly recommend this device for clinics looking to expand their treatment options.
