Acne vulgaris, commonly known as acne or pimples, is a common skin disorder that affects about 85% to 100% of people at some point in their lives. It affects people of any age, gender and race, although it is more evident in adolescents. Acne vulgaris is actually characterized by noninflammatory follicular papules or comedones and by inflammatory papules, pustules and nodules at its most acute. Acne Vulgaris occurs, as it affects areas of skin with the densest population of sebaceous follicles. Common areas affected are the face, neck, upper chest and back, although it may occur in different body parts like the head and genital area. Numerous studies have indicated that, in general, there are four main factors are responsible for the development of an acne lesion. The pathogenesis of acne vulgaris is considered multifactorial, due to this finding. These four factors that trigger the development of acne vulgaris include epidermal hyperproliferation and hyperkeratosis follicular excess sebum, Propionibacterium acnes and inflammation. The follicular hyperkeratosis and hyperproliferation of epidermal fact seems to be one of the main events in the formation and development of acne vulgaris. The results have indicated that increasing levels of androgen adrenally derivatives dehydropiandrosterone sulfate (DHEAS) correlated with the onset of microcomedones, which is actually the primary acne vulgaris lesion. This development may aggravate the follicular epidermal hyperproliferation, which may also be stimulated by an alteration in sebum and lipid levels in the lesions of acne vulgaris. Excess sebum is the second factor in the formation of acne vulgaris. It plays its role of hormonal changes largely trigger the formation of acne vulgaris. Then there is the P. acnes, which is a microaerophilic organism in many lesions of acne vulgaris. Basically, stimulates inflammation through the release of proinflammatory mediators that are scattered through the follicle wall. Some findings also suggest that hypersensitivity to P. acnes may explain why many people develop inflammatory acne vulgaris. Finally, recent studies have shown that inflammation may be a primary or secondary phenomenon in the development of acne vulgaris. Its secondary inflammatory response has been demonstrated in association with P. acnes. However, the proinflammatory cytokines IL-1? Expression has been recognized in the microcomedone, which play an important role in the formation of acne vulgaris. Acne Vulgaris, through recent discoveries that have been found to cause physical pain and psychological distress. It can even lead to scarring, which can last a lifetime, and certain diseases such as foot and arthritis may result from it.
