    Glossary Follicular Infundibulum

    upper part of hair follicle where sebum exits

    The follicular infundibulum is the upper part of a hair follicle, extending from the skin's surface down to the point where the sebaceous (oil) gland opens into the follicle. This region is crucial for the passage of sebum and dead skin cells to the skin's surface, and its blockage can lead to conditions like acne.
