“A next-generation EU-approved filter with exceptional broad-spectrum stability.”
What it does
Tinosorb S is a photostable broad-spectrum UV filter approved in the EU, UK, Canada, and Australia (not yet approved in the US). It absorbs both UVB and UVA radiation and is notably photostable — unlike avobenzone, it does not degrade in UV light. It is considered one of the safest and most effective modern sunscreen filters.
Benefits
- Broad-spectrum UVB + UVA coverage
- Photostable — does not degrade in sunlight
- Also stabilises avobenzone in combination formulas
- Low skin penetration and strong safety profile
