Know your ingredients: Mica

Mica

What it is
Mica is a naturally occurring group of silicate minerals that are found in different types of rock.

What it does
Mica reflects the light and is used in many cosmetics and personal care products to give them sparkle and shine.

Side effects
Mica can be irritating for people with sensitive skin. Because mica is made from crushed rocks, it tends to have sharp microscopic edges that can cause micro-tears when buffed onto the skin.
Mica can also aggravate acne and rosacea because, due to its heavy consistency, it requires more buffing to disperse the pigment, thus forcing makeup into the pores, clogging them.

I’m glad you like the post. Mica is one of the main ingredients in mineral makeup but the amount depends on the formula. Mineral makeup companies don’t use the same product formulation. It is usually the main ingredients in foundations, but then some brands don’t use it at all. Also, different companies may use mica of different quality.
