Science & Benefits
Tinosorb M is a hybrid UV filter that acts as an organic micro-fine particulate. It works through three mechanisms: absorption, reflection, and scattering. It is exceptionally photostable and acts as a stabilizer for other, less stable filters. It is zero-comedogenic. Its logic in acne care lies in its 'physical-like' protection without the heavy, occlusive nature of traditional zinc pastes, making it ideal for lightweight, high-SPF acne-safe fluids.
