    process by which substances pass through the outer skin layer

    Skin penetration refers to the process by which substances pass through the outermost layer of the skin, known as the stratum corneum, to reach deeper layers. This is a critical concept in dermatology and pharmacology, as it influences the effectiveness of topical medications and skincare products. Factors such as molecular size, solubility, and the condition of the skin can affect how well a substance penetrates.
