Cosmetics Europe requires samples to be tested to the Standard EN ISO 24443:2012 Cosmetics – Sun protection test methods – In vitro determination of sunscreen UVA photoprotection.
This standard has been published by CEN (June 2012) and replaces the earlier reference method (Colipa Guidelines – Method for in vitro Determination of UVA protection, 2011). The EN ISO test method is now considered as the reference method within the EU. Cosmetics Europe therefore recommends cosmetic manufacturers to use this standard to determine the UVA Protection Factor and the Critical Wavelength. For UVA protection testing, preference is given to the standardised in vitro test method which avoids the need for in vivo testing while delivering equivalent results.
We need 60g of final product and the results are emailed within 4-6 weeks of sample receipt.
In Vivo Testing
When sunscreen products are tested in vivo to determine their Sun Protection Factor (SPF), the procedure generally involves human volunteers. However, not all skin types are typically tested. Instead, the testing focuses on individuals with lighter skin types who are more susceptible to sunburn.
While in vivo SPF testing focuses on lighter skin types, it’s important for consumers of all skin types to understand that UV radiation can lead to more than just sunburn. It can cause premature aging, DNA damage, and increase the risk of skin cancer. Therefore, even individuals with darker skin should consider using sunscreen to protect against the broader effects of UV radiation.
