Hand Immersion Test

Hand Immersion Test Panelists enrolled in the Hand Immersion Test soak their hands in 2 different hand/dish washing products, once a day for 30 minutes for 5 consecutive days. Products are tested at usual dilution for hand/dishwashing solution and are randomized between the dominant and non-dominant hands of panelists. Skin reactions (redness and dryness) are…

Comedogenicity Patch test

Comedogenicity Patch test The comedogenicity patch test is aimed to assess the comedogenic potential of the test product when repeatedly applied on comedone/acne-prone skin up to 48 hours per week for 4 consecutive weeks. The test is carried out on healthy subjects under occlusive condition. Skin reactions (comedones proliferation) are assessed by a highly trained…

Anti acne

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…

Trophic / Energizing / Contraction efficacy

Trophic / Energizing / Contraction efficacy efficacy is assessed using different techniques: The extracellular matrix (ECM) dissociating enzymes (collagenase, elastase, hyaluronidase) are generally involved in cell metabolic pathways related to cell energy status, aging and skin trophic disorders. Biochemical assays can be useful to measure the marker enzyme activity, as well as the biological assays…

SPF test

SPF test: Sunscreens are regulated in all developed countries and are classified as cosmetics or over-the-counter (OTC) drugs depending on local regulations. These differences in regulatory status arise also in the testing methodology. We can assess the compliance of sunscreens according to the main countries requirements: FDA Final Rule (2011) – Static and Water Resistance…
