What is Mineral Sunscreen?
Mineral sunscreen, also known as physical sunscreen, uses natural mineral ingredients—primarily zinc oxide and titanium dioxide—to protect skin from UV radiation. Unlike chemical sunscreens that absorb UV rays, mineral formulas sit on top of skin and physically block and scatter UVA/UVB radiation through a process of reflection and scattering.
Mechanism of Protection
Mineral sunscreen: Forms a physical barrier that reflects and scatters UV rays. Chemical sunscreen: Absorbs UV radiation and converts it to heat
Active Ingredients
Mineral: Zinc oxide, titanium dioxide (often micronized) Chemical: Oxybenzone, avobenzone, octinoxate, octocrylene, homosalate
Skin Compatibility
Mineral: Generally better for sensitive skin, acne-prone skin, rosacea, and children
Chemical: May cause irritation, stinging, or allergic reactions in sensitive individuals
Environmental Impact
Mineral: Often considered reef-safe (non-nano zinc oxide is preferred)
Chemical: Some ingredients like oxybenzone and octinoxate are linked to coral bleaching
Application Differences
Mineral: May leave initial white cast (though formulations have improved significantly)
Chemical: Typically more lightweight and transparent on application
Ingredients in Mineral Sunscreen
Zinc Oxide
The gold standard mineral ingredient offering broad-spectrum protection against both UVA and UVB rays. Zinc oxide is particularly effective against UVA1 rays, which penetrate deepest into skin. Modern formulations use micronized particles or nanoparticles (though nano remains controversial) to reduce white cast while maintaining efficacy.
Titanium Dioxide
Excellent for UVB protection with some UVA protection, though not as comprehensive as zinc oxide. Often combined with zinc oxide for complete broad-spectrum coverage.
Additional Beneficial Ingredients
iron oxide: Added to tinted formulas for visible light protection, especially beneficial for hyperpigmentation and melasma
Antioxidants: Many premium formulas include vitamins C and E, green tea, or niacinamide
Hydrating components: Hyaluronic acid, glycerin, ceramides in modern formulations

Conclusion
Mineral sunscreen has evolved far beyond the thick, white paste of decades past. Today’s formulations offer elegant textures, minimal white cast, and sophisticated skincare benefits while providing gentle, effective sun protection.
