Sebaceous glands facts

The secretion of a sebum is performed by the sebaceous gland. This substance keeps the hair and skin moist and it will be the focus of this text. These glands are located on skin and they create waxy or oily matter that is named sebum and that is needed for the hair and skin lubrication. Cellular debris and fat mixture, which is comprised of cholesterol, squalene, wax esters and triglycerides, are two components of the sebum. They can also be found on some areas of skin, unlike soles and palms, but generally they are present in great quantities on the scalp and the face. Since they are associated with hair follicles, they are usually located in areas of the body with hair. Sebaceous gland, arrector pili muscle, hair follicle and hair are parts of this structure. There is another name for the sebaceous gland and it is pilosebaceous unit. There are units on the chest, upper neck, face and some other regions of the skin. Some hairless areas of the body, like nipples, labia minora, penis, nose and eyelids, also have pilosebaceous units. On these locations, the ducts located on the skin are terminated by the passing of the sebum.

Overactive Sebaceous Gland

Overactive and enlarged sebaceous gland are present during the adolescence period, and this lead to the increased secretion of the sebum due to the androgen production, which is a hormone. They are responsible for the enlargement and stimulation of the sebaceous gland. Girls between the 13 and 20 and young boys have increased androgen production. The problem of overactive sebaceous gland can lead to many problems, but the most common on is acne. This is a mild problem, but it is not always guilty of producing acne; it can cause much more serious problems, such as comedones, pimples and acne that can be created on shoulders, chest, neck, back and face. Also, furuncle, seborrheic dermatitis, asteatosis, steatoma, rosacea, seborrhea, acne, white heads may be experienced as well. These are some of the common problems found in adolescents, but adults can suffer from them as well. This condition can also cause scaly skin, pus filled lumps, skin redness and itchiness.


Many problems associated with the skin may be formed due to the grime, dirt and oil, which blocks the pores on the skin due to the overactive sebaceous gland. For treatment of this problem, you can use 2.5% benzoyl peroxide due to the reduction of fatty acids and bacteria. You can also use oral or topical antibiotics, like tetracycline or clindamycin, with trans-retinoic acid containing medications such as retin A or tretinoin. They will reduce the risk of new acne due to the reduced skin cell stickiness. Also, avoid injections, topical medications, lotions, creams, ointments, spicy food and oily food. Try to drink a proper amount of water, wear light clothes during the summer and use adequate soap for bathing and this can eliminate problems in the future.
