>I spent 400 dollars
I spent like $8 on a few red LED bulbs off Amazon instead of some "medical device" because I don't trust those puffy marketing claims that you somehow "need" some hella bougie laser to send your skin the same damn 650nm photons.

>every possible chemical and disease has been tested
No, even in 2025 new chemicals are getting discovered and new applications of existing chemicals are being found. If your post was 100% true then all the diseases would be cured already, and we're much closer with most of them than your average doctor has the brain power to actually research.
