Explanation:

Sebum is an oily secretion produced by sebaceous glands. It acts as a waterproofing agent for the skin and hair follicles. When produced in excess, it can make the skin oily. Sweat is mainly for thermoregulation and waste excretion. Cerumen (earwax) is in the ear. Collagen is a structural protein in the skin, not an oily secretion for waterproofing.

A. sebum
