The invention relates to the use of nanoscale sterols and/or sterol esters with particle diameters of 10 to 300 nm for producing cosmetic and/or pharmaceutical preparations. The particular fineness of the particles compared to known sterols and sterol esters ensures that they penetrate into the corneum quickly when applied topically.
