Ive also got facial sauna thingy, and also a sun lamp ....Has anyone used them at all?
Well although I've not, I would imagine they could work, my skin improves 110% when I go on hols, which I put down to the sun and higher temps, cold dry weather (ie a long time in the UK) plays havoc with my skin, but in summer it improves somewhat...2 weeks in somewhere like spain and I'll come back without a single mark on my face, so if these things are dishing out 'sunlight' then I'd deffo give them a go! (although be careful blah blah with UV rays etc etc).
Good luck
