The permeation of triamcinolone, hydrocortisone, prednisolone, corticosterone, triamcinolone acetonide, testosterone, and betamethasone-17-valerate through excised human stratum corneum was quantified. The time course of permeation could be adequately described by a simple diffusion model suggesting that shunt transport may not be
