The basic cause of acne is still unknown. It seems to be a multifactorial disease in which interaction of several factors play an important part in the pathogenesis. The primary event may be (a) obstruction of the sebaceous duct due to alteration in the pattern of keratinization within the follicle, (b) abnormal sebum production with excess quantities or altered composition or (c) increased bacterial colonization (proprionibacterium acnes and staphylococcus epidermi¬dis of pilosebaceous follicles which furnish the lipases responsible for hydrolysis of sebum triglycerides into free fatty acids. All three mechanisms may be involved. Obstruction of duct leads to forma¬tion of a comedone, the initial lesion of acne. A comedone can be located either in a closed follicle as a 'white head' consisting of lipid and keratin, or in an open follicle as 'black head' consisting of keratin and lipid with melanin deposition. The continual accumula¬tion of keratin and lipid may lead to rupture of the follicular wall and release of its contents into the surrounding dermis provoking an inflammatory tissue reaction.
Acid indigestion on the other hand, is similar to 'general indigestion' above, however it involves an excess of hydrochloric acid in the stomach. if Acid indigestion is experienced frequently it can wear on the duodenum and the lining of the stomach, both which are aggravating and can lead to conditions such as ulcers, which can be life threatening. It is important to know that acid indigestion is different from heartburn, which is the aggravation more specifically of the esophagus.
Tea tree oil is without a doubt the most effective topical acne treatment. It is natural too. While being cheap enough for anyone to use, it is far better than most topical acne product out there. My recommendation? Throw away all those acne treatment products that don't work and stop buying the so called "next best thing" released by big companies. Tea tree oil is better in terms of effectiveness. Another great thing with tea tree oil is that it does not cause any irritation reactions. Good for people with sensitive skin.
