The waxy layer on the outside of leaves is called the cuticle. It helps reduce water loss and protects the leaf from pathogens and environmental stresses.

This is called the integumentary system.
The Cuticle
A layer of the leaf called the cuticle cuts down on water lost by evaporation. Also, the guard cells around the stomata which can close to prevent water loss.
The waxy cuticle on the surface of a leaf helps prevent water loss by acting as a barrier. Additionally, stomata, microscopic pores on the leaf surface, open and close to regulate the exchange of gases and reduce water loss through transpiration.
The outermost layer of the skin, called the epidermis, is responsible for protecting the body from bacterial infection and preventing water loss. The top layer of the epidermis, known as the stratum corneum, acts as a barrier against outside pathogens and helps to retain moisture within the skin.
They minimize water loss
