how to fix skin redness / rosacea (full guide)

Skin redness and rosacea are caused by localized microinflammation rather than systemic inflammation, meaning normal systemic markers (DNF alpha, IL6, CRP) can be normal while localized skin inflammation persists. Effective treatments include 20% azelaic acid for anti-inflammatory benefits, mineral sunscreens (preferably Korean or Japanese) to prevent UV damage, low-dose isotretinoin (5mg daily) targeting the root cause, and PDL laser as the gold standard procedure that eliminates dilated blood vessels. Key triggers to avoid include UV damage, junk food, damaged skin barrier, and chronic stress.
