What causes acne?

The causes contributing to acne are internal and external.

INTERNAL:

Genetic, hormonal, stress (emotional), poor diet and certain drugs (cortisone).


EXTERNAL:

Lack of personal hygiene, topical pressure or friction through restrictive clothing, and comedogenic creams and cosmetics.
In most cases acne is the result of an internal malfunction manifesting as a symptom on the face, chest and back. This is often aggravated externally through improper management and the wrong kinds of products.



The pathogenic factors which causes acne are:

1. Increased production of free fatty acids due to bacterial activity.
2. Obstruction of follicular orifices (pores) with keratinized cells (dead skin), sebum and debris.
3. Increased production of keratin (dead skin)
