TLR4 and Erythema: Methods: The skin parameters were assessed: level of oiliness, hydration, pH, skin pigmentation (phototype, erythema) using a special diagnostic device (Scientific multi-probe system MPA 6, Courage + Khazaka) with simultaneous determination of monocyte subpopulations in peripheral blood expressing TLR2 and TLR4 using a CytoflexLX flow cytometer (Beckman Coulter).
