Conclusion

Topical photoprotection is a complex field, both in terms of product formulation and demonstrating efficacy. Nevertheless, it is a real public health issue. It is therefore vital to be able to market products that are safe to use and provide very high levels of ultraviolet protection.

The number of filters available to formulators is extremely limited, especially in the UVA range. It is therefore important to step up research and bring new filters to market. Several avenues are likely to be explored. On the one hand, synthetic chemistry, and in particular triazine chemistry, is an avenue to be explored in greater depth, since this family of molecules already provides very effective filters. Extractive chemistry, on the other hand, should enable the emergence of original structures that absorb strongly in the UVB and/or UVA range. We know that a number of living...
