Description: Tinosorb S is a chemical sun filter that has been approved for use in sunscreens inCanada,Australiaand the European Union. It blocks both short and long UVA rays and UVB rays as well. That's great news because it means that the reformulated Anthelios sunscreens deliver even greater broad spectrum UV protection, especially against deeper penetrating UVA rays.

Tinosorb S is photostable, meaning that it will continue to offer protection over time. And, it has an additional benefit in helping to stabilize other sun filters such as avobenzone from degradation. The ingredient has a good safety profile – it isn't associated with skin irritation and lacks hormone disruption effects associated with some older sun-filtering agents.
