Pores on the skin surface open into the <u>sebaceous glands.</u>
The mid-dermis is home to sebaceous glands, which almost always develop alongside hair follicles and have an outlet that empties into the follicular canal. The pilosebaceous unit is the name given to this grouping.
The follicle also houses an oil gland and a hair (sebaceous gland). The oil gland keeps the skin lubricated, helps remove dead skin cells, and keeps tissues from drying out. Meibomian glands, a small group of sebaceous glands that open directly onto the skin in the epithelium of the eyelid, help to improve the lubricating abilities of tears.
Function :
The sebaceous gland contributes the vast majority of skin surface lipids via its main product, sebum, which helps to seal in moisture and prevent desiccation of the skin. Because sebaceous glands empty into the hair canal, sebum mostly escapes onto the skin surface via a wicking action involving the hair shaft.
