چکیده
Sebum is secreted by sebaceous gland via holocrine secretion. It contains free fatty acid, wax and sterol esters, tr iglycerides and squalene. The sebaceous glands are distributed mainly at scalp, face, upper back and chest. The secretion of sebum is influenced by androgen and is increased at the time of puberty. There is also diurnal and seasonal variation. The sebum may increase in the morning and in summer time. Some postulate that increased glycaemic load may also increase the sebum secretion. The sebum production rate is around 1 mg/10 cm2/3 hours and increase in production is more commonly found in acne patients. The speaker has conducted a study involving 19 patients. A standard skin cleanser was applied twice daily. The sebum, skin hydration and Cardiff Acne Disability index were assessed before and 4 weeks after. There was a significant reduction in sebum level over the forehead and right cheek and the skin hydration was maintained. However, no significant difference in the acne related quality of life was noted before and after treatment. Learning points:
