More in the human body than the apocrine glands, eccrines are present in almost every part of the skin. Your skin has two types of sweat glands: eccrine and apocrine. The apocrine sweat is released around the hair follicle and is believed to moisturize the hair follicle like sebum as well as impart a specific scent. 1. associated with hair follicles of - axilla - areolae of breast - pubic region 2. secretory portion located in the deep dermis and hypodermis 3. duct empties into a hair follicle.
