March 2019 in “Experimental Dermatology” This study analyzed the cornified envelope of epidermal proteins, finding keratins dominate, which may help explain the minimal impact of deleting genes for single envelope components in congenital ichthyosis.
January 2013 in “IRIS UNIMORE (University of Modena and Reggio Emilia)” This study found that silica nanoparticles penetrate the outer stratum corneum of human skin, with surface hydrophobization potentially enhancing this penetration.

May 1991 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that trichohyalin, a protein previously thought to be restricted to hair and tongue, is also present in isolated cells within the granular layer and stratum corneum of normal human epidermis.
