This is why we have incorporated the renowned DermaScan® technology into our testing arsenal. To find out why this is a game-changer for our clients please visit our website.

Tissue induration, also known as skin hardness or firmness, is an important parameter to consider when analyzing cosmetic user trials. It refers to the degree of firmness or stiffness of the skin in response to a product or treatment.

Biocidal testing is most applicable in environments and industries where controlling microbial growth is critical to maintaining health, safety, and the integrity of products and materials. Here is a more detailed explanation of where biocidal testing is most applicable and the types of products it is most relevant for:

BS EN 13727, a crucial European standard, delineates the methodology for assessing the bactericidal action of antiseptic and disinfectant products in medical settings. This test, which simulates practical conditions, is applicable to a broad spectrum of products, such as those for surface disinfection, hand hygiene, and instrument sterilization.

Elasticity and tissue stiffness are crucial parameters when developing cosmetic products, particularly those targeting aging skin. Elasticity refers to the skin’s ability to return to its original state after being stretched or deformed, whereas tissue stiffness indicates the resistance to deformation. An Elasticity Meter is often used in product development to measure these parameters. 

Trans Epidermal Water Loss (TEWL) is a measure of the quantity of water that evaporates from the skin and passes into the surrounding environment. It is an essential indicator of the skin’s barrier function, and thus plays a critical role in cosmetic product development for several reasons.

Water testing in cosmetic products ensures the safety, quality, performance, and longevity of the products while also safeguarding brand reputation and meeting regulatory standards. It is vitally important that the quality of ingredients is monitored, and in most formulations, the main ingredient is water.

High-resolution imaging allows for detailed visualization, providing objective evidence of skin condition before and after product usage. This imaging technique helps in capturing images that can be used as visual proof of the effectiveness of cosmetic products.
