Sun protection products are not only used for protection from sunburns, but also expected to help with protection from long-term damage. From this, UV-A filters have gained greater currency. Up to recently, the choices of these filters was quite limited. In the year 2000, this situation improved. MBBT (methylene bis-bentzatriozolyl tetramethylbutylphenol), BEMT (bis-ethylhexyloxyphonol methoxyphenyl triazene) and DPBT (disodium phenyl dibenzimidazole tetrasulphonate), three new, photostable UV-A's and broad-band filters were taken onto the positive list of cosmetic UV filters. In order to demonstrate UV-A protection in Europe, many in-vivo and in-vitro methods are under discussion. The use of the most common relative in-vitro methods shows that the highest value for the 'critical wavelengths' is significantly simpler to achieve than with the 'UVA/UVB relationship'. Due to the norm developed in Japan for the in-vivo methods, PPD (persistent pigment darkening), the different photo sensitivities of conventional, photo-labile UVA filter BMDBM (butyl methoxydibenzoyl methane) can be demonstrated impressively in comparison to the modern photo-stable UVA filter MBBT. The new photo -- stable UVA/broadband filters are discussed, where the first commercial user examples can be considered.
