Acne is a common disorder of the pilosebaceous follicles with the multifactorial pathogenesis. It typically begins in adolescence when androgen hormones stimulate the production of sebum and proliferation of follicular epidermis. The openings of hair follicules become clogged with oil secretion and corneocytes. In consequence initially invisible lesions (microcomedones) and then clinically evident comedones develop. Microcomedones and comedones are further colonized by P. acnes bacteria which promote inflamed acne lesions (papules and pustules) through the production of proinflammatory mediators, free fatty acids and porphyrins.

The presence of porphyrines can be demonstrated by orange-red fluorescence in the follicle openings by examining the skin under appropriate UV-A light. The intensitiy of follicular fluorescence and the extent of facial involvement are proportional to the population densitiy of P. acnes and porphyrin content at the skin surface. Clinical improvement after therapy is accompagnied by significant reduction of the porphyrin concentration and the number of P. acnes, respectively.

Fields of Application

  • Efficacy testing of antibacterial products and drugs against P. acnes
  • Determination of the comedogenic and comedolytic activity of topically applied products
  • Applications in acne research
