Recommendations for use
Complement to UVA Filters
As this filter does not protect against the UVA spectrum, we recommend using it in combination with other filters capable of providing UVA protection.
Moreover, it is a good filter for stabilizing the notoriously unstable UVA filter, avobenzone, and works particularly well with Ensulizole to achieve high SPF protection. It is approved up to 10 % as a sunscreen in the European Union and most parts of the world, with the exception of the USA.
