Let's start with the basics. Tanzinc is not a single chemical but a specialized formulation centered around mineral UV filters, primarily Zinc Oxide. Unlike chemical sunscreens that absorb UV radiation and convert it into heat, mineral sunscreens work like a shield. They sit on top of your skin and physically block harmful UVA and UVB rays by reflecting and scattering them away.
Think of it as a tiny, invisible army of mirrors protecting your skin. This fundamental difference in mechanism is what gives mineral formulas their key advantages: they are broad-spectrum by nature, meaning they protect against both aging UVA and burning UVB rays, and they are far less likely to cause stinging or allergic reactions. This makes a product like Tanzinc an excellent choice for those with sensitive skin, rosacea, or conditions like melasma.
