With Mother’s Day approaching, many women are shopping the Mother’s Day sales at retailers grabbing deals on popular cosmetics.  Cosmetic gift sets are a hot item to give Mom on her special day.  One of the more popular cosmetic lines are mineral-based foundations, either liquid or powder.  Many opt for the powder version for that light and natural look and feel.  That natural “glow” and light feel is the result of a common ingredient in many mineral cosmetics known as bismuth oxychloride.  Consumers have been drawn to its “pearlizing” and “shimmery luster” marketed to decrease visible fine lines and/or skin discoloration.

Bismuth oxychloride is a “natural” ingredient found in many mineral cosmetics.  Though sold as a “natural” and beneficial ingredient, bismuth oxychloride is actually an inorganic by-product of copper and lead refinement. Bismuth oxychloride can often cause itching, rashes, and mild to severe cystic acne. This is extremely unfortunate, since many of the products are directed toward those who have sensitive skin. For some, the slight abrasive nature of this ingredient in their makeup can cause rosacea and acne to flare up.  Others experience minuscule abrasions within the pores that become infected pustules. mineral-powder-foundation

On the other hand, mineral cosmetics offer the benefits of leaving out other potential irritants such as preservatives, parabens, mineral oil, chemical dyes, and fragrance. For many women, trial and error is a large part of the process when selecting the cosmetic products that work best for their skin type.

Many mineral cosmetics manufacturers are looking to reduce the use of bismuth oxychloride in their products with some manufacturers looking for alternative ingredients with the same esthetic benefits without the skin irritation side effects.  Beauty is in the eye of the new and improved mineral cosmetics product holder!
