Sunburns and skin cancer caused by exposure to sunlight’s UVA and UVB radiation can be effectively prevented by using sun creams or sunscreen lotions. The active ingredients in these products are commonly aromatic compounds which absorb high energy UV-light. The allowed compounds and maximum concentrations in sunscreens differ among the US, Europe, Japan and other countries due to varying legislation. This product table lists analytical standards for UV blocking substances and the countries where they are allowed to be used.
