What is the outermost layer of the skin?

Explanation:
The outermost layer of the skin is the epidermis. It sits at the surface and acts as the protective barrier, preventing pathogens and chemicals from entering and reducing water loss. The epidermis is made of keratinized, stratified squamous epithelium, with the outermost portion called the stratum corneum, which is tough and waterproof. Beneath it lies the dermis, which provides structural strength through connective tissue, and contains blood vessels, nerves, and skin glands. Deeper still is the subcutaneous tissue (also called the hypodermis), composed mainly of fat and connective tissue that cushion and insulate the body. So, the epidermis is the layer you’d identify as the outermost.
