The sebum flow dynamics at the skin surface results from a multistep p
rocess starting with sebocyte proliferation, intracellular lipid synth
esis, cell lysis in the sebaceous duct, storage of sebum in the follic
ular reservoir, discharge through the follicular opening and spreading
over the stratum corneum. A handful of topical products may decrease
the sebum output, most of them acting at the level of the follicular r
eservoir function. Among them, elubiol exhibits a clinically relevant
effect on oily skin.
