Acne is a skin problem that affects almost all teenagers. The condition results
from the action of hormones on the skin's oil glands (sebaceous glands). The sebaceous
glands make an oily substance called sebum that empties onto the skin surface through
the hair follicle opening (pore). The mixture of oil and cells allows bacteria that
normally live on the skin to grow in the follicle openings. When this happens, pores
become clogged and pimples develop.
In most cases, pimples occur on the face, neck, back, chest, and shoulders. Acne
does not present a serious health risk, but severe acne can result in permanent
scarring. In addition, acne can have significant physical and psychological consequences,
such as causing a poor self-image, social inhibition, and anxiety.
According to Ayurveda, acne are the papules resembling the sprout on the bark of
'Shalmali ' tree, appears on the face in adolescents known as yavan pidika.
