Good question, actually.
Here’s a little known fact – Acne Vulgaris, or common Acne, is a condition which up to 85% of all people 21 and below go through at least once. That is an extremely high portion of the population which is affected by this skin disorder.
The cause of Acne is not fully known, but there are several factors which contribute to the development of this inflammatory skin disorder. Your genes play a role in this, meaning if your parents or grandparents suffered this skin condition, you will be prone to getting Acne yourself.
Most notably, there is a link to a change in hormonal activity, such as menstrual cycles and puberty. In the past the over production of sebum was considered to be the main cause of Acne. Sebum is an oily secretion of fats and the remains of fat producing cells, caused by hyperactive sebaceous glands in the skin.
Apparently, another main factor in the cause of common Acne would be the narrowing of the follicle channel, which is related to the hair being rooted in the epidermis. But this is not the only factor that could lead to a person suffering from such condition, as Stress, allergies to bacteria, anabolic steroids and a large build-up of dead skin cells could also play a role.
What has not been confirmed in any way, is the contribution a fatty diet, including chocolate, potato chips and French fries, may have on Acne. One would probably have to experiment by eating different foods until he or she is able to positively assess whether his/her Acne is adversely affected or not.
However, what probably has a tangible effect on Acne is if a person has a diet rich in refined sugar. That being said, this is due to the fact that in societies virtually unaffected by the Western way of life, acne is quite rare. These people have a low glycernic level in their diets. But it has yet to be indicated as proof positive whether minimizing high glycernic foods such as sweets, white bread and soft drinks has a positive effect on reducing the effects of Acne. But it goes without saying that keeping your consumption of these foods to a minimum could have a positive effect on your overall health.
One of the most notorious Acne myths is that it is influenced by our hygiene, or lack thereof. So if your level of personal hygiene is, to put it charitably, on the same level as a habitue of Haight Ashbury circa 1967, you need not worry about getting Acne just because of that. To make this clearer, Acne causes blockages to occur deep within the follicle or hair channel and as such cannot be washed away. So to avoid making your lesions even worse or causing new ones, you would have to use a gentle, mild skin cleanser.
