To aid in moisture retension.
A cactus breathes through its stomata. These are little holes on the flesh or skin of the cactus. Through it's thorns Cactii breathe through pores in their skin called stomates. These are generally closed during the heat of day to retain moisture and opened during the night to allow respiration to occur. Photosynthesis

A cactus' waxy skin helps it retain moisture in desert climates.
the cactus was so prickly, it actually punctured my skin.
Trehalose is a sugar which is found actually in cactus plants. It is this sugar which protects cactus from drying in deserts and retaining water as trehalose has a property of retaining water. This ingredient is used in cosmetics preparation for dry skin. Trehalose protects dry skin and retains moisture of the skin.
The cactus adapted to its harsh environment by developing thick skin to slow the evaporation of water. The leaves changed in order to reduce the surface area that water could evaporate from and over time became defensive spines to protect itself from animals trying to get inside its thick skin for the moisture. The cactus makes its food, by having chlorophyll throughout the rest of plant. That is why the entire cactus is green.

The skin of a cactus stem generally has a smooth papery feel. It is firm to the touch if healthy.

There are several answers, depending on the spikes. Answers include:To protect the plant from herbivoresTo provide a layer of still air, to protect the cactus skin from excessive heatTo provide shade to the cactus skinOverall, the purpose seems to be related in some way to the plant's survival strategies.
The outside of the cactus stem is covered with a thickened outer skin that may be glossy, leathery or waxy. The skin protects the cactus from excess water loss through evaporation. It also serves to deflect and disperse light, through its ribbing. The ribbing also allows the stem to contract or expand to accommodate more or less amounts of water. The skin is a source for growth, through its growth buds. From the buds grow the branches, modified leaves, fruits, flowers, and seeds.
i think the wax just helps it from getting harmed from the harmful rays of the heat it lives in
