1. Acne Types and Symptoms
Acne is an infectious condition of the sebaceous glands and the hair
follicles. This condition can take several forms which can be identified as
follows: Pimples, black heads, infected abscesses, cysts and sometimes
scarring although it’s rare. Acne generally develops throughout teenage
years in both males and females. To be more specific, acne begins in the
course of adolescence and usually gets worse on individuals who naturally
have oily skin. Acne severely affects adolescent males and a bit less severely
females. It can also affect middle-aged women, but it’s rare and when it
does, it’s usually much less severe. Acne is usually seen most typically over
the face. The other areas where it can occur consist of the neck, chest, back,
shoulders, scalp, and upper arms and legs. Most varieties of acne are the
result of genetics and hormonal issues and has not a single thing to do with
harmful diets or poor hygiene.

Different types of acne
Acne starts in an identical way for every one but can take diverse forms and
can behave in a unique way and in accordance with specific individual
conditions. A basic lesion known as the comedo is the beginning of acne. A
comedo is a plugged hair follicle containing oil and bacteria that when
conditions are right, grows into a full fledged pimple. As the skin continues
producing oil, the bacteria grows. The adjoining skin becomes progressively
inflamed as the white blood cells fight against the intruders. Acne can be
non-inflammatory and inflammatory.
Non-inflammatory acne
Closed comedo:
When the plugged follicle remains under the skin’s surface, the infection is
known as a closed comedo. This typically appears on the skin as white head
pimples. These pimples are normally known as whiteheads.
Open comedo :

2. When the plugged follicle grows and raptures the surface of the skin, the
lesion is known as an open comedo. The dark look of the plug or pimple isn't
because of dirt, but it is because of the build-up of melanin, the pigmentation
element of the skin. This type of pimple is known as a blackhead.

Inflammatory acne
Papule:
A papule is a small pink bump that appears on the surface of the skin.
Papules are tender to the touch and are frequently considered to be an
intermediary phase between non-inflammatory and clearly inflammatory
lesions.
Pustule:
These are little round lesions which are inflamed and consist of visible pus,
which appear red at the base having a yellowish or whitish center. Pustules
don't have a significant amount of bacteria. The inflammation is caused by
chemical irritation from sebum components like fatty free acids.
Cyst:
Cysts are pus-filled lesions which typically grow deep within the skin. These
cysts are extremely painful due to being infected. Cysts form due to the
contents of a comedo spreading over the surrounding skin. The immune
system generates pus fighting the infection which expands and this creates a
cyst. This form of acne (cysts) frequently leave deep scars.
Acne conglobata:
Conglobata is a rare but serious form of acne. This is an inflammatory form
that develops mainly within the back, buttocks, and chest. In addition, due to
the presence of pustules and cysts, there might be severe bacterial infection.
Symptoms

3. The typical signs of acne consist of persistent, recurring swellings and red
spots on the skin referred to as pimples or zits. The pimples or zits become
inflamed and get filled with pus. The pimples typically occur on the neck,
chest, face, shoulders, or upper portion of the back. Some of the other
indications consist of dark spots with open pores at the center - these are
referred to as blackheads. The bulged spots without openings are called
whiteheads. Red lumps filled with pus are referred to as pustules. Pustules
can develop from either whiteheads or blackheads. Cysts are another form of
acne. These are pus-filled lumps that can grow quite large and generally
need to be removed surgically.
