Symptoms: Acne is a skin disease affecting the sebaceous gland (glands
which produce an oily secretion). These glands are especially large
upon the nose where there openings from pits that are clearly visible.
There appears to be an individual predisposition to the disease and is
dependent on the development of the sebaceous glands which takes place
at the ages of fourteen and twenty. The condition is often associated
with dyspepsia, and lack of fresh air and exercise. In women it tends
to become worse during menstruation.
The eruption itself consists of little black spots which indicate the
mouth of small sebaceous ducts chocked with dust or dirt, from which a
long, wormy looking fatty mass can be squeezed; hard pimples generally
showing one of these blackheads on the top; little pustules surrounded
by a slight degree of inflammation, which gradually grow, burst and
then heal; and hard lumps, sometimes half in inch in diameter which
last for weeks or months, slowly suppurate and leave a permanent
scar....
