Note: It's important to remember that not all rocks are suitable for use in cosmetics. Some rocks can be harmful or irritating to the skin. Always choose cosmetics from reputable brands that use safe and tested ingredients.
It's also worth noting that the term "rock" can be quite broad. Some cosmetic ingredients, like mica, are actually minerals extracted from rocks, but they are processed and refined before they are used in cosmetics.
