Which term describes the typical thickness of the stratum corneum, commonly around twenty layers?

The measurement of how thick the outermost epidermal layer is is described by the term Stratum Corneum Thickness. This directly names the physical dimension of the stratum corneum, which is commonly around twenty layers thick. It’s the best fit because it specifies thickness itself, whereas the other terms refer to what the layer is made of (keratinocytes), the broader cell types in the epidermis, or its barrier function (water passage control) rather than its thickness. Understanding this helps explain how the skin’s barrier and hydration are affected by how thick this outer layer is, since a thicker stratum corneum can influence product penetration and moisture retention.
