X represents large interlayer cations, such as K+, Na+, Ca2+, Ba2+, Rb+, Cs+, etc. Y represents octahedral cations, such as Al3+, Fe2+, Mg2+, Cr3+, Ti4+, Fe3+, etc. Z is mainly Si4+ and Al3+; The ideal ratio of the additional anion (OH)- to (O)2- is 2:10, and (OH)- can be replaced by F- and Cl-. Most mica contain 4% to 5% water. Therefore, although they may be called mica, the chemical composition of different mica may be very different, for the purpose of research, we collectively refer to the minerals with this type of characteristics as mica group minerals.  

While mica powder is particularly beneficial for sensitive skin, it is also suitable for a wide variety of skin types, including oily, dry, and combination skin. Its versatility lies in its ability to blend seamlessly with other natural ingredients like mineral oils, plant-based emollients, and moisturizing agents, offering a solution that complements all skin needs. For dry skin, mica powder in cosmetics provides a dewy, radiant finish that adds an instant glow without emphasizing dryness or flakes. For oily skin, mica’s lightweight nature helps absorb excess oils and prevent a greasy appearance while still maintaining a luminous look.
