Causes of Acne, Types of Acne, and Treatments of Acne
Types of Acne: When excess sebum is produced by the oil gland, the dead skin cells around the pore may become more “sticky” and partially block the pore, restricting the flow of oil onto the skin surface. This results in solidification of the sebum which fills the hair duct forming a blackhead ( open comedo ) . The dark color of the blackhead is not due to dirt, but is dried oil and from a pigment (melanin) of the shed skin cells in the openings of the hair follicles.
If the partial blockage becomes complete, excess sebum can’t escape. The bacteria “Propionibacterium acnes” (short form P. acnes) that are normally present on the skin are trapped in the pore as well. They make an enzyme that breaks down sebum into a substance called “free fatty acid.” Free fatty acid is very irritating stuff, and can cause swelling, redness and pus formation. This is called a whitehead ( closed comedo ) .
Similar but a bit more serious formations are called pustules (pus-filled yellowish bumps), and nodules (firm, larger inflamed swellings below the skin).
Acne: Causes
Causes By Mayo Clinic staff
Three factors contribute to the formation of acne:
- Overproduction of oil (sebum)
- Irregular shedding of dead skin cells resulting in irritation of the hair follicles of your skin
- Buildup of bacteria
Acne occurs when the hair follicles become plugged with oil and dead skin cells. Each follicle is connected to sebaceous glands. These glands secrete an oily substance known as sebum to lubricate your hair and skin. Sebum normally travels up along the hair shafts and then out through the opening of the hair follicle onto the surface of your skin. When your body produces an excess amount of sebum and dead skin cells, the two can build up in the hair follicle and form together as a soft plug.
Acne vulgaris
From Wikipedia, the free encyclopedia Acne vulgaris Classification and external resources 
Acne of a 14-year-old male during puberty ICD-10 L70.0 ICD-9 706.1 DiseasesDB 10765 MedlinePlus 000873 eMedicine derm/2 MeSH D000152
Acne vulgaris (commonly called acne) is a common human skin disease, characterized by areas of skin with multiple noninflammatory follicular papules or comedones and by inflammatory papules, pustules, and nodules in its more severe forms. Acne vulgaris mostly affects the areas of skin with the densest population of sebaceous follicles; these areas include the face, the upper part of the chest, and the back. Severe acne is inflammatory, but acne can also manifest in noninflammatory forms.[1] Acne lesions are commonly referred to as pimples, blemishes, spots, zits, or simply acne. Acne lesions are caused by changes in pilosebaceous units, skin structures consisting of a hair follicle and its associated sebaceous gland, changes which require androgen stimulation.
Acne occurs most commonly during adolescence, affecting more than 96% of teenagers, and often continues into adulthood. In adolescence, acne is usually caused by an increase in male sex hormones, which people of both genders accrue during puberty.[2] For most people, acne diminishes over time and tends to disappear—or at the very least decrease—after one reaches one’s early twenties. There is, however, no way to predict how long it will take to disappear entirely, and some individuals will carry this condition well into their thirties, forties and beyond.[3]

Acne Rosacea
Middle aged adults often suffer from acne rosacea .This is characterized by flushing of the face and red nose caused by inflamed bumps. This infection takes place on chin and forehead. Because of the flushing face, it gives rise to wrong perceptions of the person being drunk, although this type of acne has absolutely nothing to do with drinking. In the severe form, Acne rosacea causes red nose or bulbous nose (rhinofima), especially in men. To read more about what is Rosacea, click here.
Infantile acne takes place in newborn babies, although not frequently. Sometimes it’s even present at the time of birth. It’s a mild form of acne and settles down in a few months. The reason is supposed to be fetal hormones, but sometimes excessive testosterone and follicle stimulating hormones are also found to be cause of infantile acne.
Acne rosacea definition
Definition of Acne rosacea
Acne rosacea: This term is actually a misnomer! The appropriate term is simply rosacea which is a chronic skin disease that affects the middle third of the face with persistent redness over the areas of the face and nose that normally blush: mainly the forehead, the chin and the lower half of the nose. The tiny blood vessels in these areas enlarge (dilate) and become more visible through the skin, appearing like tiny red lines (called telangiectasias). Pimples can occur that look like teenage acne.
Unlike acne, rosacea is not primarily a plague of teenagers. It occurs most often in adults (ages 30 to 50), especially those with fair skin, and affects both sexes but tends to be more common in women but worse in men. Unlike acne, there are no blackheads or whiteheads in rosacea.
Acne Vulgaris
Sonya K. Brown, M.D., and Alan R. Shalita, M.D.
Acne vulgaris, folliculitis, and acne rosacea are common disorders of the pilosebaceous units, which consist of sebaceous glands and their associated hair follicles. The most common anatomic sites of involvement are those that have the largest and greatest density of sebaceous glands: the face, neck, upper chest and back, and upper arms.
Acne Vulgaris
Acne vulgaris is a common disorder that peaks in incidence around the time of puberty. The pathogenesis of acne vulgaris is multifactorial. Abnormal keratinization in the upper canal of the hair follicle causes formation of hyperkeratotic, adherent plugs that are derived from desquamated epithelial cells, resulting in comedones (appearing clinically as whiteheads and blackheads), the noninflammatory lesions of acne vulgaris. Androgens stimulate the secretion of lipid-rich sebum from the sebaceous glands; sebum, in turn, provides a growth substrate for the commensal Propionibacterium acnes, an anaerobic diphtheroid. Proliferation of P. acnes is particularly facilitated by the anaerobic environment of the follicles that are plugged by comedones. This results in the production of proinflammatory mediators that are largely responsible for the appearance of the inflammatory lesions of acne vulgaris: papules, pustules, and nodules (Figure 1 and Figure 2).

Acne is Extremely CommonAlmost everyone has at least a little of it at one point or another in their life. Though acne is supposed to go away after the teens, it can persist for many years. A few whiteheads or blackheads or an occasional small red pimple can usually be tolerated. However persistent or severe acne is much more troubling.

Acne – Topical Therapies
Knowing how and why acne forms and the role that so many effective oral medications play is indispensible in really understanding acne. That leaves topical therapy, appropriate skin care, the latest Sci-Fi treatments and exciting new developments for us to discuss.
Topical Therapies
A hot topic in acne therapy is how to best handle breakouts with topicals. Some don’t want to take pills, and others have extenuating circumstances and can’t take pills. Most simply want to get clear fast and understandably want to incorporate whatever measures they can to maximize treatment. Topicals are as varied in their actions as systemic therapy. They are an invaluable means for treating minor outbreaks and rounding out therapy.
ACNE TREATMENTS
TREATMENTS: As tempting as it can be to squeeze whiteheads and blackheads, DONT! It can do more harm than good. Squeezing whiteheads and blackheads can cause harm to the skin.
Dont touch blackheads. Dont attempt to squeeze, prod, puncture, or touch your them. The only thing this does is inflame them, and possibly pushes contents of the blackhead deeper into the tissue. This can result in tissue injury. The best thing to do is leave a blackhead alone. An untouched blackhead is an uninflamed blackhead.
Squeezing whiteheads is potentially MORE harmful that squeezing blackheads. This whitehead comedones are more likely to become inflamed lesions if touched. Any attempt to touch or squeeze these regions will result in further inflammation.
