What skin layer is targeted by chemical exfoliants?

Chemical exfoliants are specifically formulated to target the stratum corneum, which is the outermost layer of the epidermis. This layer consists of dead skin cells that can accumulate and contribute to a dull complexion, clogged pores, and a variety of skin issues.

By utilizing chemical exfoliants, such as alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs), these products work to break down the bonds between these dead skin cells, helping to slough them off more easily. This process not only enhances the overall appearance of the skin by promoting cell turnover but also allows for improved absorption of other skincare products and treatments.

When discussing other layers, the dermis lies beneath the epidermis and is involved in deeper skin structure and function; targeting this layer would require different types of treatments. The subcutaneous layer provides cushioning and insulation and is not comprised of cells that are removed through exfoliation. Although the epidermis includes the stratum corneum, the primary focus of chemical exfoliants is the stratum corneum itself. Therefore, the correct answer emphasizes the specific action and intent of chemical exfoliation on the outermost skin layer.
