Who has tried blue light therapy ?

I just read the study about the effects of blue light on vitiligo and figured I could give it a try.

article is there > https://pubmed.ncbi.nlm.nih.gov/36575871/

i already use opzelura and have a uvb narrowband light panel and so far results are quite good but I would be curious to try the blue light and was wondering if you had recommandations about the lamp I should buy.

internet is not exactly helpful today.

i have kept these 2 but I am suspicious . The first one is strangely cheap and the second one looks like a scam
