What is the subaceous gland?

The sebaceous gland is a small gland in the skin that produces an oily substance called sebum. This oil helps to lubricate and protect the skin and hair, maintaining moisture and preventing dryness. Sebaceous glands are typically associated with hair follicles but can also be found in hairless areas of the skin. Overactivity of these glands can lead to oily skin and conditions like acne.
