Best Acne Treatment To Get Rid Of Acne And Acne Scar:How Does Acne Develop?
Doctors describe acne as a disease of the pilosebaceous units
(PSUs). Found over most of the body, PSUs consist of a
sebaceous gland connected to a canal, called a follicle, that
contains a fine hair (see “Normal Pilosebaceous Unit”
diagram). These units are most numerous on the face,
upper back, and chest. To get the best acne treatment to get rid of this condition we have to understand some facts.
The sebaceous glands make an oily
substance called sebum that normally empties onto the skin
surface through the opening of the follicle, commonly called
a pore. Cells called keratinocytes line the follicle.
The hair, sebum, and keratinocytes that fill the narrow
follicle may produce a plug, which is an early sign of acne.
The plug prevents sebum from reaching the surface of the
skin through a pore. The mixture of oil and cells allows bacteria
Propionibacterium acnes (P. acnes) that normally live on
the skin to grow in the plugged follicles. These bacteria produce
chemicals and enzymes and attract white blood cells
that cause inflammation. (Inflammation is a characteristic
reaction of tissues to disease or injury and is marked by four
signs: swelling, redness, heat, and pain.) When the wall of
the plugged follicle breaks down, it spills everything into the
nearby skin – sebum, shed skin cells, and bacteria – leading
to lesions or pimples.
People with acne frequently have a variety of lesions, some
of which are shown in the diagrams below. The basic acne
lesion, called the comedo (KOM-e-do), is simply an enlarged
and plugged hair follicle. If the plugged follicle, or comedo,
stays beneath the skin, it is called a closed comedo and produces
a white bump called a whitehead. A comedo that
reaches the surface of the skin and opens up is called an open
comedo or blackhead because it looks black on the skin’s surface.
This black discoloration is due to changes in sebum as it
is exposed to air. It is not due to dirt. Both whiteheads and
blackheads may stay in the skin for a long time.

Other troublesome acne lesions can develop, including the
following:
• Papules – inflamed lesions that usually appear as
small, pink bumps on the skin and can be tender
to the touch
• Pustules (pimples) – papules topped by white or
yellow pus-filled lesions that may be red at the base
• Nodules – large, painful, solid lesions that are lodged
deep within the skin
• Cysts – deep, painful, pus-filled lesions that can
cause scarring.
