Telling states apart1
Slow recovery of blood vessel tone may explain redness after the skin barrier has recovered
Where this hypothesis actsPersistently reddened skin after scratching has been prevented
What is proposedDistinguish residual redness from active inflammation and ongoing barrier damage
With whatInstrument or assay
HowCombine colorimetry and blood-flow assessment with water loss, permeability, serial microdamage recording and responses to repeat loading
Possible resultExpected persistence of redness after barrier function and cellular inflammatory indicators have normalized
