The Solar Protection Factor (SPF) of a topically applied sun care product indicates the skin protection level against UVA and UVB rays.
To obtain the SPF protection value, in vitro and in vivo tests (clinical tests) must be carried out.
Health authorities of each country regulate these tests by imposing strict standards to companies that are launching sun care products on the market. Thankfully, a will for a global harmonization of these rules exists. Evalulab offers tests to prove the effectiveness and safety of your sun care products.
Once the tests are completed, the values of “SPF” on the packaging are accurate and precise product claims that comply with regulations.
