Efficacy Tests Skin

Efficacy tests on skin in vivo

The C+K devices are worldwide used as standard instruments in efficacy testing and claim support of cosmetics, pharmaceuticals, raw materials, househol/personal care products, detergents as well as food and food supplements.

The devices are eays and quickly to use, thus perfectly suitable to study the product properties on the skin in each phase of the development process.

The extrenal testing laboratories/CROs all over the globe use the C+K equipment to perform final product tests for documentation.
Efficacy Tests Hair Care

Meassurements on hair & scalp

Besides measurements on the skin, assessing parameters on hair and scalp play a big role in the developement of shampoos, hair care and cosmetics, as well as food and food supplements.
Efficacy Tests Nail Care

Measurements on nails

Assessing the nail properties in vivo is gaining more and more focus in assessing efficacy of nail care and nail cosmetics. New, innovative measurement systems allow exploring a whole new world of claims.
Efficacy Tests Eye Care

Meassurements around the eyes

Measurements around the eyes are basic efficacy and safety tests for products applied to the eyes (e.g. contact lenses, eye drops) or near the eyes (e.g. skin care and decorative products) and their claim support.
