Broad Spectrum

This is a term that’s used in reference to a sunscreen’s ability to protect the skin from both UVA and UVB rays. In order to use the term broad spectrum, a sunscreen product must pass a critical wavelength test and confirm its rating of SPF15+. If it has an SPF less than that it can only use broad spectrum claims in terms of preventing sunburn and not in regards to anti-ageing or preventing skin cancer.
