Anti acne efficacy is assessed using different techniques:
Antimicrobial efficacy testing is an useful step to screen the efficacy of ingredients/products in counteracting the bacteria involved in the onset/development of acne. The inhibitory concentration of the ingredient/product on Propionibacterium acnes and Staphylococcus epidermidis growth is assessed through microbiological tests carried out according to the international recognized standards specifically adapted to the scope.
On humans, the non comedogenic potential assessment is an essential step to ensure that the product is not cause of acneic lesions occurrence; while product efficacy on noninflammatory and inflammatory acne lesion is assessed by means of acne lesions counts and image analysis.
