The waxy layer that surrounds the leaf and helps prevent excessive water loss is called the cuticle. It acts as a barrier that reduces evaporation and protects the leaf from environmental stressors.

Typically, the waxy layer of a leaf, known as the cuticle, is thinner than the epidermis. The cuticle is a thin, waterproof layer that helps prevent water loss from the leaf, while the epidermis is a thicker layer of cells that provides protection and support to the leaf.
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.
The protective substance that restricts water loss from a leaf is called cuticle. It is a waxy layer on the outer surface of the leaf that helps to reduce water evaporation and protect the leaf from drying out.
The Cuticle
The outer layer of a leaf's skin is called the waxy cuticle, or just cuticle. You could also include the next layer, the epidermis layer. Mostly, though, the leaf's skin is called the 'Leaf surface'.
