Acne

(acne vulgaris) Skin condition common in young people at puberty, which usually clears up between the twentieth and twenty-fifth year, although in some people it can persist until the age of thirty. Acne results when the sebaceous glands in the skin produce more sebum (fat) as a result of stimulation by sex hormones. If a gland becomes blocked, sebum accumulates and the gland swells well beyond its normal size; the blockage shows on the skin as a black spot, or blackhead. The accumulated sebum contains various bacteria which turn it into fatty acids. If small cracks occur in the wall of the sebaceous gland, the fatty acids can leak deeper into the skin and cause inflammation. The blackhead becomes red, and a small abscess may form, which scars over when healed. Many try to cure acne by squeezing out the blackheads, but this should be done with great care. If the spot has a black core, this can be removed with clean fingers. A spot with a white core is so firmly sealed that there is great risk of cracks, leakage and inflammation, and it is therefore best to leave it alone. There are many commercial remedies available for which their manufacturers make great claims. Cleansing lotions for greasy skin have little effect. Remedies which may help are those that dissolve callous tissue, preventing blockage of the sebaceous glands. If such remedies do not produce the required result the doctor can prescribe medication partly to counter the effects of sex hormones; also bacteria in the sebum can be destroyed by antibiotics, but such medication has to be used for long periods.
