Hi KorvenI am curious, did you guys take any aspirin when the lipofuscin appeared?
When I started experimenting with Peaty stuff in the summer of 2019 I took a lot of aspirin to prevent sunburn. During that time I developed lots of new yellow/brown'ish spots on my arms. There was another user here who reported the same thing happening from taking aspirin. Since I stopped taking it I haven't gotten any new ones and the old ones are fading away.
My theory is that aspirin chelates the iron in your body, and when this aspirin-iron chelate is exposed to UV radiation you get more lipid peroxidation. Maybe this is only a problem with excess iron levels.
There's also a connection between skin tags and insulin resistance. Some people don't do so well on OJ/milk protocol so that may be another factor.
To answer your question, no I didn't take aspirinYour theory makes me theorize....aspirin is high in salicylates. I did eat (unknowingly) lots of high salicylates foods.
This makes me wonder if salicylates are the actual chelators of your theory....?
