Numerous comprehensive studies have shown that blue light, particularly high-energy visible light, can harm skin cells. These forms of radiation have the potential to trigger oxidation reactions, DNA damage, erythema and pigmentary changes, and may also be associated with photoaging.

Sunscreens that protect the skin from only ultraviolet (UV)-B and UVA rays can thus no longer be sufficient to help prevent skin damage from sunlight. Hence, there is a need for products containing filters that can provide broad-spectrum photoprotection. 

As a result of this need, a new sunscreen formulation has been developed that protects against solar radiation with wavelengths ranging from UV to visible light, using an organic sun filter with unique optical properties, with a good safety profile for humans and the environment, as demonstrated in different studies. This sunscreen containing TriAsorB, along with three other UV filters to offer broad-spectrum sun protection with a high sun protection factor (SPF50⁺), has been shown to effectively prevent multiple forms of cellular photodamage, in particular, blue light-induced oxidatively generated DNA lesions. 

In summary, the available data suggests that the regular use of the TriAsorB-containing sunscreen could help prevent solar radiation-induced skin damage and the development of signs of premature skin aging, as well as photodermatoses caused or exacerbated by visible light.
