What is the correct order of the layers of the epidermis from superficial to deep?

The correct order of the layers of the epidermis from superficial to deep starts with the Stratum Corneum, as it is the outermost layer that provides a barrier to moisture loss and environmental damage. Following this layer is the Stratum Germinativum, also known as the Stratum Basale, which is the deepest layer responsible for the generation of new skin cells. This order places the Stratum Granulosum next, where keratinocytes begin to lose their nuclei and undergo keratinization, making it crucial for the skin's protective barrier. The Stratum Spinosum follows, which contributes to the strength and flexibility of the skin due to intercellular connections.

Understanding this specific order is critical in esthetics, as each layer plays a significant role in skin health, appearance, and function. It informs treatment decisions for various skin concerns, as different products and procedures target specific layers of the epidermis for effective results.
