Tinosorb M

Product Description

Direct from our B2B specialized production line, Tinosorb M is a revolutionary "hybrid" UV filter that bridges the gap between organic and inorganic sunscreens. Its unique mechanism involves microfine organic particles that absorb, scatter, and reflect UV radiation simultaneously, providing a comprehensive dermal shield. It is the gold-standard choice for formulators aiming to achieve high SPF/PA ratings with a non-greasy, elegant skin feel.
