The Great Defender
When it comes to skincare, protection is paramount, and not just from the sun. At Linde Esthetics & Wellness Studio, we believe in products that go beyond the basics, offering comprehensive care that aligns with our philosophy of customized, results-driven treatments. Circadia Circa-Shield Mineral Sunscreen SPF 30: a product that not only shields your skin from harmful UV rays but also defends against environmental stressors, ensuring your skin remains healthy and radiant.
What Circadia Says About It
Circadia Circa-Shield is a broad-spectrum mineral sunscreen formulated with 17.3% zinc oxide, providing effective protection against both UVA and UVB rays. But its benefits don’t stop there. This sunscreen is designed to combat oxidative stress and digital pollution — factors that contribute to premature aging and skin damage. Its unique blend of ingredients works synergistically to protect, hydrate, and soothe the skin.
It’s intended for all skin types.
How It Works & Key Ingredients
Circa-Shield works by creating a strong, protective barrier between your skin and the environment, helping you stay one step ahead of sun damage, pollution, and digital stressors that can accelerate aging. At the heart of this sunscreen is Zinc Oxide (17.3%), which physically shields your skin from harmful UVA and UVB rays. Blue Oléoactif® and NatureSoft® 880GT bring antioxidant protection, calming irritation and defending against environmental aggressors. Micah® helps reflect light, reducing visible signs of stress and keeping your skin looking smooth and resilient. Together, these ingredients empower you to face the day confidently, knowing your skin is guarded, nourished, and cared for.

The formulation is beautifully balanced so you get complete protection and comfort in one step. It shields your skin from UV rays and pollution while leaving a soft, velvety finish that never feels heavy.
Why Our Clients Love it
Circa-Shield has quickly become a favorite because it helps clients feel confident about their skin again. It defends against environmental stressors while supporting the skin’s natural balance, leaving it soft, smooth, and calm. For those noticing changes in their skin during perimenopause or menopause, it’s like having a daily safety net—one that feels good and truly works.
How to Use It Safely & Effectively
- Apply liberally to face and neck 15 minutes before sun exposure.
- Reapply at least every 2 hours, or more frequently if swimming or sweating.
- Use as the final step in your morning skincare routine, following your cleanser and any serums or moisturizers.
Pro Tip: For optimal results, pair Circa-Shield with Circadia’s Chrono-Calm Serum. This combination targets redness and supports skin resilience, providing a comprehensive solution for sensitive or reactive skin.
