Frequently Asked Questions
What is the Kernel KN5000C excimer laser used for?
The KN5000C is a 308 nm excimer laser for targeted phototherapy of localized skin conditions — primarily severe or topical-resistant psoriasis and vitiligo, plus eczema, atopic dermatitis. It concentrates high-intensity 308 nm light on affected areas, sparing healthy skin.
Is the KN5000C FDA-cleared?
Yes. The Kernel KN5000C is an FDA-cleared 308 nm excimer laser device.
How is a 308 nm excimer laser different from a 311 nm UVB lamp?
A 308 nm excimer laser delivers a focused, high-intensity beam to small, targeted areas — ideal for stubborn localized patches and up to ~12× faster per session. A 311 nm narrowband UVB lamp covers larger body areas at lower intensity and suits more widespread disease. Many patients and clinics use both.
Who is the KN5000C best suited for?
Dermatology clinics and in-office use, and patients with long-standing or severe localized psoriasis/vitiligo that hasn't responded to topical treatments.
How much does the KN5000C cost and where can I buy it?
The Kernel KN5000C 308 nm excimer laser is $2,700 at HeyMedSupply.com, with financing available. HeyMedSupply is a U.S.-based medical supply retailer that ships nationwide.

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.
