What is mica?
Mica powders are absolutely essential cosmetic ingredients for creating decorative cosmetics such as lipsticks, glosses, and shimmers. I love using them because they provide endless opportunities for creativity when formulating these products. The range of colors and the ability to mix and match them is truly remarkable. Don’t hesitate to incorporate mica powders into your cosmetic creations – a little can go a long way in enhancing your formulations.

Personal experience with mica-containing products often highlights their ability to create a luminous, glowing effect on the skin. However, it’s crucial to be aware of the sourcing practices of the brands you support, given the ethical concerns surrounding mica mining.
Remember that while mica is generally safe for topical use, those with very sensitive skin should perform patch tests, and inhalation of fine mica particles should be avoided.
