Is mineral-based make-up automatically safer?
Written by certifiedorganicQuestion: Is mineral-based make-up safer for you than make-up bought at drug stores or department stores? Most of the mineral-based make-up contains titanium dioxide and/or silica, and some contain iron of some type. Is this okay for your skin? I am wondering how such make-up is absorbed into the body, too!
Answer: Like all cosmetics, mineral-based products raise more questions about their safety than answers. Many mineral-based make-ups contain (or potentially contain) nano-size ingredients, which are 10 to 1,000 times smaller than their normally-sized counterparts and are more likely to be absorbed into the body through the skin because they’re so small.
One recent study by the National Center for Toxicological Research found that nano-sized particles could be detected throughout the lymphatic system within minutes after being deposited in the skin of mice. And once nano-particles are absorbed by the body, studies to date suggest that they are quite damaging–for instance, they can cause emphysema-like symptoms when absorbed into the lungs and are toxic to a variety of cells. In short, it is a good idea to avoid inhaling mineral-based cosmetics–be careful to not create dust, as particles can quickly absorb deep into the lungs–and avoid using them on damaged skin where the likelihood of absorption is dramatically increased.
As for the second part of the question, we have a limited understanding of the ingredients titanium dioxide, silica, and iron, as used in cosmetics. Why don’t we know more? Because the FDA doesn’t require companies to test their own products for safety.
