Non-specific cellular components in skin

The term Non-specific cellular components in skin refers to the collective biological structures of the integumentary system, such as the stratum corneum, keratinocytes, and the lipid matrix, which are affected by drugs through non-molecular mechanisms (NCBI: Skin Barrier Function, 2022). These components primarily function as a protective barrier against environmental pathogens, UV radiation, and dehydration. In clinical pharmacology, this target is associated with topical agents that do not bind to specific receptors but instead alter the physical or chemical environment of the skin (StatPearls: Keratolytics, 2023). For example, keratolytics like salicylic acid work by dissolving the intercellular cement that holds keratinocytes together, while emollients like petrolatum create a physical barrier to prevent transepidermal water loss (DrugBank: Salicylic Acid, DB00906). This category is often used in pharmacological databases to describe the site of action for treatments of hyperkeratosis, xerosis, and various forms of dermatitis. Because it lacks a specific molecular identity, it is not considered a traditional therapeutic target for drug screening or precision medicine. Instead, it serves as a functional designation for drugs that provide symptomatic relief or structural modification to the skin surface.

Drugs targeting these components typically act through non-specific physical or chemical processes, such as keratolysis (dissolving the intercellular cement), occlusion (preventing transepidermal water loss), or caustic destruction of tissue (StatPearls: Keratolytics, 2023).
