Question

skin gland which when inflamed cause acne

Answer 1

Sebaceous glands in the skin release oil to keep the skin in proper condition...

Sometimes due to excess of release of the oils(sebum) in the hair follicles(mostly during puberty). This abnormal reaction affects the process in which dead skin cells are shed which causes them to block the secretion of oil from the sebaceous glands and a acne is formed in this place.
