FIGURE 3 . Averaged skin LC-OCT intensity profilesR (z ) as a function of depth of one volunteer before (black
dashed line) and after (black solid line) OC with mixture of
Polyethylene glycol, Oleic acid and Propylene glycol with linear
regression fit lines of epidermal and dermal layers and correspondingµ s estimated values. Round insets display LC-OCT
horizontal sections of dermal layer at 200 µm depth before (t = 0 min)
and after OC (t = 11 min). The graphs next to the insets are the
corresponding pixel intensity distributions.
Relative changes (in % of intact skin value) of scattering coefficients\(µ_{s}^{\text{epi}}\) and \(µ_{s}^{\text{der}}\) (of epidermal and
dermal layers, respectively) for the nine OCA and a control condition as
a function of time are presented in Figure 4 . Similar results,
but for epidermal/dermal scattering anisotropy factorg epidermis and g dermisare presented in Figure 5 . SD bars that represent the variation
between three volunteers vere removed from the graphs for the sake of
clarity (due to strong overlapping between bars) and presented
separately in Table 2 (mean values over 10 timepoints) with
respect to optical property, layer and OCA used.
