General skin proteins

General skin proteins is a collective term for the various structural and functional proteins that constitute the skin's layers, primarily the epidermis and dermis. Key members include keratins, which form the intermediate filaments of the cytoskeleton in epithelial cells, and collagen and elastin, which provide the extracellular matrix with tensile strength and recoil properties (StatPearls, "Physiology, Skin"). Other significant proteins include filaggrin, which is vital for the assembly of the skin barrier and the production of natural moisturizing factors (NCBI, "The Skin Barrier"). In a clinical context, these proteins are often the indirect or non-specific targets of topical agents designed to enhance barrier function, promote wound healing, or mitigate the effects of aging. For example, keratolytics like salicylic acid work by breaking down keratin aggregates to treat hyperkeratotic conditions. Because this term refers to a broad class rather than a single molecular entity, it is generally considered a descriptive category in pharmacology rather than a specific drug target. Therapeutic strategies involving these proteins often focus on replacing lost components, such as collagen fillers, or protecting existing structures from environmental degradation. Monitoring the integrity of these proteins is essential in managing chronic skin diseases like atopic dermatitis and psoriasis.
