You mean this review mamadunn? http://www.occmakeup.com/faq4.html and http://www.sehsc.com/PDFs/Guidance%20for%20Aerosol%20Applications-Sep%2001.pdf I guess if you are concerned, then airbrush isnt for you. :nix: Its not like a person can wear a mask to apply it! You could hold your breath while applying and quickly move to another area. Just a thought.Is silocone harmful when used in an airbursh applicator like "temptu?" I was interested in purchasing this product then I saw that it had silicone in. In one review someone stated that this could cause lung cancer. I am a cancer (uterine) survivor and don't want to use something that might be harmful. Thanks for any information you might have.
