From the Guidelines
Mineral sunscreen is generally better for aging skin. Mineral sunscreens containing zinc oxide and titanium dioxide sit on top of the skin and physically block both UVA and UVB rays, providing immediate protection upon application. These ingredients are less likely to cause irritation or allergic reactions, making them ideal for sensitive or aging skin that may be more reactive. Mineral sunscreens also offer better protection against UVA rays, which are primarily responsible for premature aging and wrinkles. According to the U.S. Food and Drug Administration, broad-spectrum sunscreens with a sun protection factor of 15 or greater, such as those containing zinc oxide and titanium dioxide, protect against both UV-A and UV-B radiation and reduce the risk for skin cancer and early skin aging 1.
Key Benefits of Mineral Sunscreen
- Provides immediate protection upon application
- Less likely to cause irritation or allergic reactions
- Offers better protection against UVA rays, which contribute to premature aging and wrinkles
- Contains antioxidants and other skin-beneficial ingredients to combat free radical damage
For best anti-aging results, use a broad-spectrum mineral sunscreen with SPF 30 or higher daily, applying approximately a quarter-sized amount for the face and reapplying every two hours when outdoors. Modern mineral formulations have improved significantly, with many options now available that don't leave a white cast and blend well with different skin tones. The protective mechanism of mineral sunscreens provides an effective physical barrier against the sun's damaging rays, helping to prevent further photoaging while supporting your skin's health.
