contimageSun Protection Factor (SPF) is a number determined experimentally indoors by exposing subjects to a UVB spectrum meant to mimic noontime sun. The amount of light that induces redness in sunscreen-protected skin, divided by the amount of light that induces redness in unprotected skin determines the SPF of the test product.

BioScreen offers all standard SPF methods to determine the SPF of a test product, including but not limited to static tests, water resistant tests, and UVA and UVB tests that are in compliance with the requirements of all global regulatory agencies.
