Protection against Infrared light
Prolonged exposure to Infrared Light (IR) is mainly caused by natural light and is broken down into IR-A (700 nm to 1400 nm) and IR-B (1400 nm to 2500 nm). Since this exposure is involved in skin lesions, IR protection factors must be comparable between products, and provide information on the balance of UV, visible and IR protection in a single product.
WENEOS has been at the forefront of the development of in vitro methods for assessing the Blue Light (BL) – also known as High Energy Visible (HEV) – Visible (VIS) and Infrared (IR) protection offered by sun protection products. It is a fully validated and impartial independent test.
Note: This test method has not been reviewed or standardized by ISO (International Organization for Standardization), the FDA (U.S. Food and Drug Administration) or any other worldwide regulatory agency. The test report does not provide any guarantee regarding the labeling and/or substantiation of claims, implicit or explicit.

In Vitro Infrared Light
This innovative in vitro method consists in assessing the IR protection levels expressed by the IR-CW (UV/VIS/IR balance) and %IR (percentage of IR protection intensity) of a sunscreen product over the entire spectrum (from 290 nm to 2500 nm by breaking down the IR-A and IR-B part) measured using a spectrophotometric method. To take account of any potential photoinstability, the product was pre-irradiated before measurement. Finally, this method relies on the use of in vivo SPF results to scale the absorbance curve.
