in korea and japan
there was serious skin problem which is chronic inflammation (cheilitis , pimple , dermatitis , atopic)
so many people had suffered for chronic inflammation.
doctor wanted to find cure or cause and they know chronic inflammation usually be caused by allergy
.then they found
a lot of people diagnosed with chronic inflammation now are cured
cause was various.
lip product , dentifrice , metal , cosmetic
but main cause is metal. if your water pipe is corroded, that thing can release metal
if you have artificial metal in your body (like dental metal or joint), that thing can release metal
the most terrifying is that metal circulate through blood and cause chronic inflammation.
there is many case.
maybe your dentist dosent understand (especially USA , Europe)
but a lot of japanese dentists and korean dentists, doctor warn of chronic inflammation by metal
if you want checkup. you can use heavy metals test and dental patch test.
then remove possible cause.
i think some of you can be cured because korean and japanese was cured
