The causes of acne are not
yet fully known. The genetic factor is the only cause recognized by scientists so far. However, some scientists
believe thatstress, poor hygiene, hormones, environment
(pollution, sun exposure) and certain foods can encourage the development of acne.
Exposure – while a limited amount ofsun
exposure is good for the skin, excess aggravates acne, and causes
other damages to the skin includingskin cancer.
Hormones - hormonal factors are also suspected
in developing acne. This cause is more common among young men, with relative exacerbation in women during
Diet -The relationship between acne and foods
(meats, chocolate, etc.) is not fully proven, but some fatty foods may contain benzene and chlorine pollutants
that might induce or exacerbate acne.
risk of developing acne runs in families. It is shown in many studies that those who have family history of acne
tend to suffer from the disease more easily than those who do not.
Bacteria - The proliferation of bacteria such as
Propionibacterium acnes can provoke acne. Propionibacterium acnes is a bacterium that normally present on most people's skin and throughout the
gastrointestinal tract in humans and many other animals. It does not cause infection; however, it aggravates
inflammation of the follicle when there is an excess sebum production, or when the skin is exposed to certain
Pollution - Exposure to certain pollutants,
including chlorine, increases the risk of acne. Some pesticides, perhaps because of their character endocrine
disruptor (hormonally active agent), seem to be able to trigger episodes of acne called
Hyperseborrhea - An excessive sebum (oil) production,
origin hormonal, is also responsible for acne, some scientists believe. This natural oil of the skin serves to
protect it from external aggression, forming a thin film lipid at its surface. At puberty, the increase production
of certain hormones (testosterone in particular) causes an excess of pilosebaceous glands activity resulting
in skin disorders such as acne.
