Hi and thank you!
I change the cream on mine when it seems to either be disappearing, if I accidentally wipe it off when I check them or it when it seems to be looking like… how do I describe it… like it’s becoming clumpy? I’m not too sure how other people do it though. This is my first time doing UV treatment too
I’m not actually too sure how hot my bulb gets…
It does get pretty hot I think as I leave it on for quite a long time through the day.
It’s probably worth being extra careful with homemade UV chambers, especially since mine is literally a thin cardboard box beside my bed
