In-Vivo Testing

Sunlight, a source of life and energy, creates major health challenges like sunburn, pigmentation, wrinkles, dermatitis, and ageing.  Eurofins CRL offers a full spectrum of human subject based research to meet a wide range of regulatory guidelines required for the world’s markets.

SPF measurement is performed on a panel of at least 10 human adult volunteer test subjects with selected skin types to demonstrate the potential for sun-burning skin reactions. The test panel is selected from subjects who do not have any history of sensitivity to skin product ingredients and who have an appropriate health history.

The water resistance test indicates that a sunscreen product’s labeled SPF protection is retained for a certain period of time after immersion in circulating water. The determination of a water resistant claim is performed by standardized and reproducible methods under the FDA, ISO, and AS/NZS guidelines.  Types of water resistance testing available are as follows:

Similar to water resistance SPF testing, sweat resistance testing takes place in our custom built environmentally controlled chamber.  Here we can adapt various means of activity to induce sweating to evaluate the “staying power” of a particular SPF formulation under various exercise and environmental conditions.

Testing is conducted by lightly spraying water onto the test site prior to test product applications.  UV exposures are then administered to the test products per the requested testing methodology, followed by an SPF or UVAPF value determination.  This application technique can be added to all FDA, ISO, and AS/NZS testing methods.

Testing is conducted by applying and removing sand from test products in order to simulate the action of being on the beach.  UV exposures are then administered to the test products per the requested testing methodology, followed by an SPF or UVAPF value determination.  This resistance testing can be added to all FDA, ISO, and AS/NZS testing methods.
