The Mineral Foundations, eyeshadows, blushes and concealors made at CMH Essentials contain zinc oxide and titanium dioxide that act as a sun reflector to block the harmful effects of the suns uva and uvb rays. This is a major benefit during the long days of spring and summer when the sun is out for up to sixteen hours a day. Since synthetic dyes, preservatives, perfumes and fillers are avoided in the composition of our mineral makeup, there is little risk of skin sensitivity to the ingredients, resulting in a considerably reduced risk of longer-term allergic reactions. To receive the benefits of mineral makeup yourself, make sure you buy all natural, cosmetic grade mineral makeup from a source you trust.
