Daily exposure to environmental stressors like UV rays, pollution, and oxidative stress can accelerate visible signs of aging, weaken the skin’s natural defenses, and disrupt moisture balance. Sunscreen is essential, but many formulas fail to provide hydration or support long-term skin health.
Most conventional sunscreens rely on chemical UV filters that can irritate the skin, clog pores, or cause sensitivity. Some ingredients also raise health and environmental concerns. There’s a clear need for a gentle, mineral-based option that protects while also nourishing the skin, supporting the barrier, and maintaining comfort and balance throughout the day.

Frequently Asked Questions
| Question | Answer |
| Is Sun Shield suitable for all skin types? | Yes! Our formulations are designed to be gentle, effective, and non-irritating for all skin types. |
| How do I apply Sun Shield? | Apply three to four pumps onto the face and neck, massaging thoroughly until absorbed. Use as the last step in your morning skincare routine. |
| Are there any tips to reduce potential white cast? | Try warming it up first. Rub Sun Shield between your hands before applying — this helps the formula spread more evenly and absorb more quickly, reducing the appearance of any white cast and giving you a smoother finish. |
| Can this replace my make-up primer? | Yes! Once absorbed fully, Sun Shield doesn’t clog pores and delivers a smooth, hydrated base that creates an even canvas for makeup while providing powerful SPF protection. |
| Should I still apply Sun Shield if I am indoors? | Yes! Even if you’re not sunbathing or spending long hours outside, your skin is still exposed to UVA rays. Whether you’re driving, sitting near a window, or simply walking to your car or into a building, these rays can still reach your skin and contribute to premature aging. Daily use of Sun Shield helps protect against this subtle, everyday damage while also defending your skin from environmental stressors and free radicals — all of which can speed up visible signs of aging. |
Manufacturing, Health, and Ingredients FAQs
| Question | Answer |
| Why do you use zinc oxide instead of chemical sunscreen filters? | We use zinc oxide because it offers broad-spectrum sun protection while aligning with our clean formulation standards. Unlike chemical filters, which absorb UV rays and can sometimes irritate the skin or raise health and environmental concerns, zinc oxide sits on the skin’s surface and reflects UV rays. It’s a gentle, effective mineral filter that’s safe for sensitive skin and non-comedogenic. |
| Is your zinc oxide non-nano? | Yes. We use non-nano zinc oxide, meaning the particles are not small enough to penetrate the skin. Instead, they sit on the surface, forming a physical barrier that reflects and scatters UV rays. This makes our SPF both effective and safe, supporting broad-spectrum protection without compromising skin integrity. |
| Can I use Sun Shield with my medication? | Sun Shield is formulated with hydrating, clean, nourishing ingredients — but it’s always a good idea to speak with your healthcare provider or pharmacist before introducing any new skincare products. They can help ensure that the products are a good fit for your unique needs and any treatments you're currently using. |
| Is Sun Shield safe for pregnant or nursing women? | As with any new skincare product, we recommend consulting with your healthcare provider before starting use during pregnancy or while nursing. They can provide personalized advice to ensure the products are safe for you and your baby. |
| How should I store Sun Shield? | Keep in a cool, dry place away from direct sunlight to maintain potency and texture. |
