Mica
Mica is a naturally occurring mineral that gives cosmetics a soft, pearlescent shimmer. It is widely used in UK beauty products such as eyeshadows, highlighters, blushes and nail polishes to add a delicate light-reflecting glow. Completely inert and gentle, it is suitable for all skin types and creates that sought-after lit-from-within finish.
How it works in skincare
In cosmetics and skincare, mica functions as a colourant, opacifier and pearlescent agent. Its fine, plate-like particles reflect and scatter light, producing a silky, luminous effect without being glittery. In pressed powders, creams and liquids it improves slip, adhesion and texture, helping products glide smoothly over the skin while providing a sheer, light-diffusing veil that softens the appearance of fine lines.

Mica is a naturally occurring silicate mineral mined from metamorphic and igneous rocks. It is sourced primarily from India, Brazil and China and is carefully milled into ultra-fine, cosmetic-grade flakes or powder.
