    Recommend.

    Posted by Customer on March 17, 2025

    I compared several devices and decided to give the LED lamp a try. I wanted my own machine to maintain my vitiligo between doctor’s visits. After three weeks of use, I haven’t experienced any side effects. The built-in skin test at the beginning is especially helpful in avoiding overuse.

    No regret at all!

    Posted by Angeles on February 27, 2025

    I used to visit my doctor’s office three times a week for vitiligo treatments on my face and hands, but I really wanted a device to treat myself at home. Hey Med recommended their Excimer LED, and I have no regrets! The 308nm Excimer LED works just like the 308nm Excimer Laser, which is exactly what I was receiving at the clinic. The device is small, lightweight, and easy to use. I’ve been able to manage my pigmentation and even see further improvements after 2 months. Highly recommend it for anyone looking for a 308nm UV lamp!
