Sebaceous glands release an oily secretion through the hair follicles called sebum that lubricates the skin and prevents drying.
Apocrine glands, mostly found in the armpits and groin area of humans, are sweat glands that secrete an oily fluid that usually carries an odor.
Eccrine glands are sweat glands that regulate body temperature by releasing a watery secretion that evaporates from the surface of the skin, which significantly lowers the body temperature. 
Ceruminous glands are sweat glands that combine their secretion with sebum and dead epidural cells to form ear wax (cerumen).
