Does red dotted fluorescence on my skin visible under UV light represent a bacterial infection?

Hello doctor,

According to the doctor, I have red dotted fluorescence on my skin caused by certain bacteria. This fluorescence (visible under UV light) is mainly on parts of my face around my nose and chin, my scalp, and a little bit on the upper part of my chest. At first, I thought it was paint particles as my job exposes me to environmentally hazardous waste, but apparently, it is not. Regardless they have been present for several years now on my skin. The particles, mostly red (orange-red-pink), are stuck very hard. After much effort, I can scrape off one particle at a time (or scrape) with some sharp tool. I generally have dry skin on specific body parts, including my lower legs and hands (I wash my hands often at work). A dry or irritated scalp has been a problem for me for many years. Then, almost ten years ago, I suddenly developed rosacea on my face. My queries are what kind of bacteria do you think it could be (if it is bacteria and not paint particles)? Would it be worth paying to have a biopsy done? Could this provide any valuable information? Does these bacteria spread to the brain, and if so, how would I know, and should I be concerned as there seem to be links between certain bacterial infections (I assume this is an infection) and diseases related to the brain? According to doctors, nothing can be done about these bacteria that glow under UV light. Is it also your opinion that nothing can be done about them?

Hi doctor,

Thank you for your answer. According to one doctor, it is so-called porphyrins that cause fluorescence. At the same time, porphyrins seem to be a kind of disease. My follow-up question is whether my symptoms should be classified as suffering from some kind of porphyrin disease or not, and that it may, in fact, be the porphyrin that is the central issue and not the bacteria (perhaps difficult to determine). Kind regards.
