Has anyone tried one of the handheld n-UVB lamps for eczema/psoriasis and had good results? I really don’t want to keep using steroid creams and her skin is much better in the summer so I hoped it might help. But they’re £200 so it’s an expensive experiment, and it sounds a bit too good to be true. Would love to hear some feedback either way. Website reviews don’t give much away! Thanks.
