The term acne, in totality, does not mean JUST pimples.
Acne is a term for plugged pores (blackheads, whiteheads),
pimples and even deeper lumps (cysts or nodules), that occur on the face,
neck, chest, back, shoulders and even the upper arms.
There are several variations of
acne that skin experts coined.
Here are some.
Acne Vulgaris (common acne) includes several types of lesions,
usually called blackhead, whitehead, papules, pustules,
nodules and cyst.
Mild to moderate acne vulgaris is characterized by:
Blackheads- are caused by
partially blocked pores.
The black appearance is caused by melanin pigment
from dead skin cells. Blackheads
tend to be stable structures, and often take a long time
to clear.
Whiteheads- are caused by
completely blocked pores.
The white appearance is caused by the bacteria
inside turning the sebum into free fatty acid.
The whitehead differs in color from the blackhead
because the opening of the plugged sebaceous follicle to
the skin’s surface is closed or very narrow, in
contrast to the distended follicular opening of the
blackhead.
Neither blackheads nor
whiteheads should be squeezed or picked open, unless
extracted by a dermatologist under sterile conditions.
Tissue injured by squeezing or picking can become
infected by staphylococci, streptococci and other skin
bacteria.
Papules- are small, red, tender
bumps or spots. A
group of very small papules and microcomedones may be
almost invisible but have a "sandpaper" feel
to the touch. A papule is caused by localized cellular
reaction to the process of acne.
Pustules- are larger, red and
inflamed-pus filled spots.
On the other hand, severe
acne vulgaris is characterized by:
Nodules- are large and hard
bumps under the skin’s surface.
Unlike
a papule, a nodule is characterized by inflammation,
extends into deeper layers of the skin and may cause
tissue destruction that results in scarring. A nodule
may be very painful.
Cysts- are similar to nodules
but can be severely inflamed and infected.
Acne Rosacea is a
variant that typically causes a red nose and is more
common in older people than in young people, mostly
affecting those who are aged 30 and above.
It commonly appears as red rash, which are
normally confined, to
the cheeks, nose, forehead and chin. The redness is
often accompanied by bumps and pimples. Blood vessels
may also become more visible on the skin. People with this kind of acne rarely have pimples.
These flashes can be triggered by certain foods
like spicy foods and alcohol
