Filaggrin: from history of discovery to clinical usage (literature review)

Abstract

The article is of an overview nature and contains up-to-date information about one of the main factors in the violation of the skin barrier, filaggrin dysfunction, which is a component of the natural moisturizing factor. The data on the leading role of the filaggrin defect in the pathogenesis of a number of dermatoses make it an attractive target for the creation of topical dermatocosmetics in order to compensate for its deficiency. The first and only registered emollient with a modulator of filaggrin activity from unsaponifiable fractions of vegetable oils is filagrinol, which stimulates the maturation of profilaggrin by activating ATPases involved in dephosphorylation of profilaggrin and inducing the incorporation of histidine into the granular layer [30]. It is expected that thanks to plant lipids this formula enhances the skin’s ability to renew, significantly slowing down the aging process and restores the skin’s water-holding capacity, thereby normalizing the degree of hydration.
