The Visiopor® PP 34 camera uses a specific UV-light to visualize the fluorescing acne lesions of an area of minimum 8 x 6.4 mm. The orange-red fluorescence indicates the presence of Propionibacterium acnes bacteria within clinically non-evident (follicular impactions and microcomedones) and clinically evident lesions (comedones, papules and pustules).
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.
There are numerous applications in cosmetology and dermatological research especially in the field of acne.
A very interesting recent application is the evaluation of the duration of UV-A protection in vivo. UVA protection is a very important factor in modern sun screen products. When applying UVA protection to the skin, porphyrin fluorescence visible before with the special UV light of the Visiopor® is no longer visible and can only be seen again, when the UVA protection on the skin surface is gone.
