The cuticle. It's usually not that thick, but with succulents, it's really thick and waxy to hold in as much water as possible.
A leaf is composed of many differing layers with specific purposes. The outermost layer is cuticle of the leaf. The cuticle is a protective film that covers the epidermis

Most chlorophylls are expected on the top side of the leaf where sunlight hits directly.
There is a waxy layer called the cuticle that reduces evaporation from the leaf. It is produced by the epidermal cells of the leaf.
Cortical bone, or compact bone, is one of two main types of osseous tissue. Cortical bone is dense and forms the surface of bones, contributing 80% of the weight of a human skeleton. It is extremely hard, formed of multiple stacked layers with few gaps. Its main function is to support the body, protect organs, provide levers for movement, and (shared with cancellous bone) store minerals. The other major type of bone is trabecular or cancellous bone; it is spongy and makes up the bulk of the interior of most bones, including the vertebrae.
On a leaf the palisade cells are located within the mesophyll layer. It is the layer that is closest to the upper epidermis of a leaf.
The outermost layer of a root is called the epidermis. It is a single layer of cells that protects and covers the root. In stems and leaves, the outermost layer is also called the epidermis, and it serves a similar protective function.

According to biologists, the protective outer layer of a leaf is called the cuticle. Normally, the cuticle contains a waxy substance which protects the leaf from moisture loss.
