    Amazing product!!! For the past few months, I have been struggling with eczema which I had not experienced since i was a small child. I’ve been using this religiously for a month now and am seeing a definite difference. This product has soothed my itchy hands, dry and cracked fingers. It soothes and gives me immediate relief. Thank you so much

    I’ve had serorhea dermititis for 40 years and doctors couldn’t fix. I shed so much I only wore light colors because it looked like it was snowing. It took a month of daily treatment but I only have one spot on my eyebrows that flakes. I can wear all colors now, even black.

    I have only been using this product for a month but I see a difference in my psoriasis outbreak in my arms and one leg. I see slight improvement in my back. It is still early in the process. The product is easy to use and the timer insures that I do not burn my skin. I discussed with my doctor before buying.

    I held off on buying this for months because it is pricey (though much cheaper than other UVB lights). I wish I’d gotten it sooner! I am definitely saving money, and more importantly, time, being able to use this at my own convenience at home whenever I have a flare up. It’s very easy to use and very effective. I’m really happy with using this light to treat my psoriasis without medication.
