**Photoaging protection technology:**
UV radiation accounts for about 80% of skin aging processes. This filter goes beyond simply blocking UV — it targets four main signs of photoaging: moisture loss, decreased elasticity, hyperpigmentation and freckles, and dullness of complexion. Thanks to multi-stage inhibition of melanin formation — from its production to migration — it provides comprehensive anti-spot care.
