Other answers:

sebaceous gland → acne, Cutibacterium acnes (formerly Propionibacterium acnes)

apocrine gland (aka sweat gland) → The substance secreted is thicker than eccrine sweat and provides nutrients for bacteria on the skin: the bacteria's decomposition of sweat is what creates the acrid odor.

eccrine gland → used to secrete stuff inside the body (ie salivary glands, pancreatic glands)

dermis → middle layer of skin.

melchior To tweak the above a little, eccrine glands are more commonly known as "sweat glands," although sweat glands that are apocrine do exist in the armpits and perineal area, though they do not contribute to cooling. +5

acidfastboi Per what @melchior said: "Eccrine glands are the major sweat glands of the human body, found in virtually all skin, with the highest density in palm and soles, then on the head, but much less on the trunk and the extremities" - Wiki +2
