Rate and topography of follicular sebum excretion. 1987

Department of Dermatology, University of Liège, Belgium.

We have designed a combined method using a lipid-absorbent tape and skin surface stripping to evaluate the relationship between the follicular sebum excretion rate and the microanatomy of the follicular duct openings. Many sebaceous follicles appear quiescent in normals and with acne patients. Most of the large spots on the lipid-absorbent tape are due to the confluence of smaller ones. 'Open' comedones in acne are functionally closed.

D012627	Sebaceous Glands	Small, sacculated organs found within the DERMIS. Each gland has a single duct that emerges from a cluster of oval alveoli. Each alveolus consists of a transparent BASEMENT MEMBRANE enclosing epithelial cells. The ducts from most sebaceous glands open into a HAIR FOLLICLE, but some open on the general surface of the SKIN. Sebaceous glands secrete SEBUM.	Gland, Sebaceous,Glands, Sebaceous,Sebaceous Gland
