Epidermis
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.

Both have a protective outer layer.
The outer skin of a leaf is called the epidermis. This layer serves as a protective barrier against physical damage, pathogens, and water loss. In many plants, the epidermis is covered by a waxy layer called the cuticle, which helps reduce water evaporation and protect against environmental stressors.

The cuticle - a waxy layer that protects a leaf's moisture.
The main parts of an Elodea leaf are the cuticle (protective outer layer), epidermis (outer layer of cells), palisade layer (primary site of photosynthesis), spongy mesophyll layer (site of gas exchange), and stomata (pores for gas exchange). The cuticle protects the leaf, the epidermis provides structure, the palisade layer helps in photosynthesis, the spongy mesophyll layer aids in gas exchange, and stomata regulate gas exchange.
