FAQ
How does PROTECT help prevent premature aging?
PROTECT defends against premature aging by combining non-nano zinc oxide with Ectoin, a powerful extremolyte. Zinc oxide provides broad-spectrum UV protection, preventing sun-induced damage that leads to wrinkles, loss of elasticity, and hyperpigmentation. Meanwhile, Ectoin shields skin from pollution, blue light, and oxidative stress, all of which accelerate aging. By reinforcing the skin barrier, reducing inflammation, and protecting against environmental aggressors, PROTECT helps maintain a smooth, resilient, and youthful complexion every day.
Why is zinc oxide the best choice for sunscreen?
Broad-Spectrum Protection
Zinc oxide is the only single-ingredient that offers broad-spectrum defense against UVA, UVB, and even UVC rays. UVB rays are known to cause DNA damage leading to skin cancer, while UVA rays contribute to photo-aging, resulting in wrinkles, roughness, and age spots. Notably, if a sunscreen isn't labeled as broad-spectrum, it only shields against UVB rays.
Safety and Stability
Unlike some chemical sunscreens, zinc oxide is photostable, meaning it doesn't degrade when exposed to sunlight, ensuring consistent and long-lasting protection. Additionally, it's non-irritating and suitable for sensitive skin types, making it a preferred choice for many individuals.
Environmental Considerations
We've chosen non-nano zinc oxide to protect our oceans. Chemicals like oxybenzone, octinoxate, and others found in many sunscreens can harm coral reefs, affecting their reproductive cycles and worsening the effects of coral bleaching. In contrast, non-nano zinc oxide is considered safe for marine life, including coral reefs. Studies have shown that certain chemical UV filters can harm aquatic life, including corals, leading to bans in various regions. By choosing sunscreens formulated with zinc oxide, you're not only safeguarding your skin but also contributing to the preservation of our precious marine ecosystems.
Is PROTECT only for suncare?
Not at all. PROTECT is so much more than just a sunscreen. Beyond shielding your skin from UV rays, it’s infused with nourishing, hydrating, contouring, and reparative ingredients that support overall skin health. It also defends against pollution and blue light, which can contribute to hyperpigmentation, collagen breakdown, and premature aging. Whether it’s sunny or cloudy, indoors or outdoors, PROTECT is a daily step for healthier, more resilient skin.
Is PROTECT safe for use during pregnancy and on children?
For children under 4 and pregnant women in their third trimester, consult a doctor before use. While butyloctyl salicylate is a widely accepted ingredient in clean, EWG-verified sunscreens (including those formulated for babies and pregnancy) conclusive data on salicylate use in these populations is limited. Out of an abundance of caution, we recommend seeking medical guidance before use.
Is PROTECT reef-safe?
Yes! PROTECT is formulated with biodegradable ingredients and non-nano zinc oxide, making it safe for both your skin and the ocean. Unlike chemical sunscreens that contain oxybenzone, octinoxate, and other reef-harming compounds, PROTECT uses zinc oxide: the safest and most effective mineral sunscreen ingredient. It provides broad-spectrum protection without disrupting marine ecosystems, making it a responsible choice for those who care about both skin health and environmental impact.
