See, contrary to belief... I don't know everything. LOL That is new info... I know mica is made from crushed rock but never thought it had microscopic edges. That makes total sense on why it itches like crazy. But again, it's not all mica based products - I have so many products where the first or second ingredient is mica or is primarily mica but MicaBella/Beauty is the only one I ever have a problem with. The line of "certain coated mica based products will wreak havoc... due to its' heavier consistency..." has me thinking that the MicaBella/Beauty mica is one of those "certain coated" products. Maybe the mica is not as finely milled as other mica, maybe it has a coating on it that's heavier but that info is pretty right on the money for me, especially since I DO suffer from rosacea.

Oh goodness. I wonder what's different about their mica and how it would cause a reaction?!
Mica (Sericite) as a general rule is safe for the skin and usually will not cause any significant problems for women with normal complexions; however for those of us, like me, with sensitive, allergy prone skin issues, this ingredient can cause severe distress to the wearer. Mica is made from pulverized (crushed) rock which tends to have sharp microscopic edges causing micro-tears when buffed onto the skin. It can also cause further irritation to women with acne and rosacea making both of these conditions worsen. Certain coated Mica based products will wreak havoc on acne prone skin due to its' heavier consistency which requires more buffing onto the skin in order to disperse pigment and keep it from slipping into fine lines. It is this same action which forces the makeup into the pores which in turn can plug them and create an environment for more acne to grow.
