“…D/L 2 is the first-order rate constant of the anthocyanin diffusivity (D) in the stratum corneum to the thickness (L) squared of the barrier [28]. To apply Equation (A1) to determine these constants, some assumptions are made about the system [28]. The assumptions are: an infinite dose is applied, that the stratum corneum is a homogenous barrier and contains no permeant at t = 0, and that the diffusivity of the drug within the stratum corneum is slow compared to uptake by the cutaneous microcirculation, or a "sink" condition occurs for the permeant at the interface between the stratum corneum and the viable epidermis [58].…”

“…Typically, when using tape-stripping to evaluate bioequivalence between topical formulations, SC thickness is determined at one skin site to normalise the DPK data obtained at adjacent sites [1]. This approach assumes, of course, that SC thickness is similar, on the whole, across the ventral forearm.…”
