Sebaceous glands are current everywhere in the body besides on the palms, the soles and dorsal surfaces of the hand and foot. They are notably giant and quite a few on the scalp, the face, the back and the front of the chest. Every sebaceous gland is composed of a number of lobules of epithelial cells. The duct of every lobules converge in direction of the primary sebaceous duct which usually opens into hair follicle (pilosebaceous unit). Solely a small variety of sebaceous glands open immediately on the surface of the skin (the prepuce, labia minora, eyelids, nipples and lips).
The gland’s secretion, sebum, is fashioned by fatty degeneration of the epithelial cells of the gland. The entire sebaceous cells and its contents are then eradicated into the duct (Holocrine course of) and is excreted on to the pores and skin floor through the lumen of the hair follicle. Sebaceous gland exercise is below hormonal control. Androgens are essentially the most potent stimulants of seburn production while oestrogens suppress sebaceous gland activity. Seburn accommodates a fancy mixture of lipids i.e., triglycerides, wax esters, squalene, cholestrol ester and cholesterol. The sebum acts as a lubricant and controls moisture loss from the epidermis. Another advantage of sebum is protection of skin from fungal and bacterial infection.
ACNE VULGARIS
Zits vulgaris is a persistent inflammatory dysfunction of pilosebaceous unit characterised by the development of comedones, papules, nodules and cysts.
Aetio pathogenesis
Pimples predominantly impacts adolescents. The peak incidence is between ages 14 and sixteen years in girls and sixteen and 19 years in boys.
The basic reason behind pimples continues to be unknown. It appears to be a multifactorial disease through which interplay of a number of components play an vital half within the pathogenesis. The first occasion may be (a) obstruction of the sebaceous duct resulting from alteration within the pattern of keratinization inside the follicle, (b) abnormal sebum production with excess quantities or altered composition or (c) increased bacterial colonization (proprionibacterium acnes and staphylococcus epidermidis of pilosebaceous follicles which furnish the lipases liable for hydrolysis of sebum triglycerides into free fatty acids. All three mechanisms may be involved. Obstruction of duct leads to formation of a comedone, the preliminary lesion of acne. A comedone can be positioned both in a closed follicle as a ‘white head’ consisting of lipid and keratin, or in an open follicle as ‘black head’ consisting of keratin and lipid with melanin deposition. The continuous accumulation of keratin and lipid could result in rupture of the follicular wall and release of its contents into the encompassing dermis provoking an inflammatory tissue reaction.
Certain factors equivalent to genetic, climate, stress use of drugs and comedogenic chemical substances are identified to modify acne.
Scientific Options
The illness is characterised by a fantastic number of lesions which differ from patient to patient however most patients have a number of kinds of lesions. Various varieties of lesions are comedones (black or white), papules, pustules, nodules and cysts.

Topical Remedy
This is designed to produce peeling of the skin, restore normal keratinization and produce a bactericidal action. Common peeling agents are sulphur (three 5%), resorcin (3 5 %), benzyl peroxide (5 10%) and retinoic acid (0.025 0. 1%). Peeling agents ought to be utilized a few times a day, taking care to avoid extreme irritation.
Topical antibiotics embody erythromycin (1 2%) clindamycin (1 2%) and benzyl peroxide (5 10%). Benzyl peroxide has bacterio static properties in addition to its action as a peeling agent. Comedones could also be expressed with a comedo extractor and cyst should be drained and injected with corticosteroids.
Systemic Therapy
The antibiotics similar to tetracycline, erythromycin, clindarnycin and cotrirpoxazole are mostly used in the treatment of pimples vul¬garis. Tetracycline is the therapy of alternative for reasonable to extreme: acne and is given within the dosage of 250 mg three to 4 instances day by day with a gradual discount to a maintenance dose of 250 mg once a day for several months, Just lately, oral retinoid (isotretinoin) has been discovered to be very efficient drug in the administration of extreme type of acne, particularly nodulo cystic pimples and conglobata.
