Hi there, I hope you don't mind but I have been using the Philips Blue Light control for around a year and am now selling the unit.
I posted a note on another thread but I suspect it sort of dropped out as the thread is quite old. Anyway, someone may find this useful so here goes?
I have been using the Philips BlueControl and it has settled down the Psoriasis on my hands after a major flare up about a year ago. So far it has not returned so I am selling the unit on EBay if anyone is interested.
It did work but took some time (several weeks) to see the effect and once they had settled down I got a bit lazy putting the thing on each night for 30 minutes, So far (touch wood) they have stayed ok... Anyway do take a look.
