Nobody completely sure what cause acne, experts believe the primary cause is a rise in androgen levels - androgen is a type of hormone, when androgen rise, human become an adolescent, rising androgen levels make the oil glands under your skin grow the enlarge gland produces more oil, excessive sebum can break down cellular walls in your pores, causing bacteria to grow,
some say that ance could also be genetic, medications which contain androgen and lithium may cause acne, greasy cosmetics/ Make-Up may cause acne in some people, hormone changes during pregnancy may cause acne too,
Ance happens when sebaceous (Oil) glands attached to the hair follicles are stimulated at the time of puberty by elevated levels of male hormones, sebum (oil) is a natural substance which stimulated at the time of puberty by elevated levels of male hormones. Sebum (oil) is a natural substance which lubricates and protects the skin. Associated with increased oil production is a change in the manner in which the skin cells mature so that they are predisposed to clog the follicular openings or pores. The clogged hair follicle gradually enlarges, producing a bump. As the follicle enlarges, the wall may rupture, allowing irritating substances and normal skin bacteria access into the deeper layers of the skin, ultimately producing inflammation.Inflammation near the skin's surface produces a pustule; deeper inflammation results in a papule (pimple); deeper still and it's a cyst. If the oil breaks though to the surface, the result is a "whitehead." If the oil accumulates melanin pigment or becomes oxidized, the oil changes from white to black, and the result is a "blackhead." Blackheads are therefore not dirt and do not reflect poor hygiene.
Factors that may worsen acne These factors can trigger or aggravate an existing case of acne:Hormones. Androgens are hormones that increase in boys and girls during puberty and cause the sebaceous glands to enlarge and make more sebum. Hormonal changes related to pregnancy and the use of oral contraceptives can also affect sebum production.Certain medications. Drugs containing corticosteroids, androgens or lithium are known to cause acne.Diet. Studies indicate that certain dietary factors, including dairy products and carbohydrate-rich foods — such as bread, bagels and chips, which increase blood sugar — may trigger acne.
Culprit #1: Hormones For the majority of acne sufferers, the trouble begins at puberty, when the body begins to produce hormones called androgens. These hormones cause your sebaceous glands to enlarge, which is a natural part of the body's development. However, as an acne sufferer your sebaceous glands are overstimulated by androgens, and this can continue for decades. Androgens are also responsible for acne flare-ups associated with the menstrual cycle and, on occasion, pregnancy.
Culprit #2: Extra Sebum When the sebaceous gland is stimulated by androgens, it produces extra sebum. In its journey up the follicle toward the surface, the sebum mixes with common skin bacteria and dead skin cells that have been shed from the lining of the follicle. While this process is normal, the presence of extra sebum in the follicle increases the chances of clogging – and can cause acne.
Culprit #3: Follicle Fallout Normally, dead cells within the follicle shed gradually and are expelled onto the skin's surface. But if you've got overactive sebaceous glands these cells shed more rapidly. Mixed with a surplus of sebum, the dead skin cells form a plug in the follicle, preventing your skin from finishing its natural process of renewal. While not acne itself, this plug encourages the growth of acne bacteria.
Culprit #4: Bacteria The bacterium Propionibacterium acnes (P. acnes for short) is a regular resident of all skin types. It's part of your skin's natural sebum maintenance system. Once a follicle is plugged, however, P. acnes bacteria multiply rapidly, creating the chemical reaction we know as inflammation in the follicle and surrounding skin.
Culprit #5: Inflammation When your body encounters unwanted bacteria, it sends an army of white blood cells to attack the intruders. This process is called chemotaxis or, simply put, the inflammatory response. This is what causes your pimples to become red, swollen and painful. The inflammatory response is different for everyone, but studies have shown that it is especially strong in adult women. That is why many women continue to suffer from acne well after their teen years. It's definitely not the chocolate.
Myths about acne There are several myths about what causes acne Food Many people say that eating chocolate or greasy food causes acne, but this isn't true. There isn't any evidence that acne is caused by what you eat. However, eating a balanced diet is good for your general health so aim to eat as healthily as you can.Bad hygiene Some people believe that acne is caused by bad personal hygiene, but this is not true. If you are going to get acne, you will get it no matter how much you clean your skin. Too much cleaning can make the condition worse by removing the protective oils in your skin.Make-up There is also a myth that wearing make-up can cause spots, but there is no evidence that this is the case. The less you touch your skin, the fewer bacteria will be spread to your skin. If you wear make-up, wash your hands before putting your make-up on and always remove it before going to bed.Treatments for acne Acne will usually go away on its own, but it can take many years.
