FAQs

  • What is CoTZ?

    CōTZ stands for Contains Only Titanium and Zinc. All of our products use only the mineral sunscreen active ingredients Zinc Oxide and Titanium Dioxide in sheer, elegant formulas.

  • Why should I use a mineral sunscreen?

    Mineral sunscreens work differently from chemical sunscreens, and we believe those differences make mineral sunscreens healthier:

    Mineral sunscreens reflect and refract UV light away from the skin. Chemical sunscreens work by absorbing ultraviolet light on/into your skin and creating a reaction that produces heat.

    Mineral sunscreens don’t penetrate the skin. Chemical sunscreens can penetrate the skin and reach other tissues.

    Mineral sunscreens rarely cause skin allergies. Chemical sunscreens are more likely to cause allergic reactions.

  • What makes your mineral sunscreens different from other mineral sunscreens?

    CōTZ mineral sunscreens are known for their uncommonly light, silky feel and virtually invisible appearance on skin. That’s because we use only the highest quality active and inactive ingredients, delivering excellent protection in formulas that are a pleasure to wear.

  • Are your products reef safe?

    All CōTZ products meet Reef Friendly guidelines, meaning they are 100% free of the chemical sunscreen actives Oxybenzone and Octinoxate, as well as all other chemical sunscreen actives. There is currently no specific test for Reef Friendly certification.
