Enhanced skin blood flow and sensitivity to noxious heat stimuli in papulopustular rosacea

[Guide]

"Heat pain thresholds of areas affected by rosacea were lower than those of nonaffected areas. In addition, subjective burning perception was increased in rosacea patients when compared with control subjects. Although PPR-affected skin had elevated skin blood flow when compared with nonaffected skin, this was not significant for ETR-affected skin."
