Love these questions! Regarding zinc oxide, the limits in the US, Canada, and Europe are 25% Zinc oxide in any product (to avoid toxicity) and we are at 17%, which allows us to stay well under that limit, but still get the SPF 30 claim. You're also absolutely right that we are replacing oxybenzone, homosalate and octocrylene - all banned in the EU - which have been linked to cancer, hormone disruption, and skin allergies. Longer term, it is possible we will find another alternative to zinc oxide, but at this time it is hands down the safest SPF ingredient to be using. All regulatory bodies will agree.

Your question about iron oxide is super interesting! Like any tinted product (even artificially tinted like a foundation), there is always some risk to the product getting on and staining clothing or accessories. Because our product is primarily meant to be used on the face, we are less concerned about this. We may create another version of this product for body, and will need to be much more conscious of the possibility of staining. We also formulated the product to have a fast "dry-down" time, meaning it absorbs relatively quickly into the skin. After a minute or two, it should not be rubbing off easily on clothing or other accessories.

Wouldn't a 17% zinc oxide concentration give you an SPF of 27, not 30?

Thank you for taking the time to answer my questions. You are obviously trying to cover all the bases with product ingredients and that will hopefully position you for success. Good luck to you all!
