Bacteria and microbes cannot survive in pure minerals such as mica, titanium dioxide, and sericite, all of which are common ingredients in Bella Terra's foundations, mascaras, glosses, serums, creams, and moisturizers. All-natural, hypoallergenic, and animal-free products provide natural sun protection while containing no alcohol, dyes, or preservatives. Mica, a long-lasting translucent powder, strongly adheres to skin and stays in place throughout the day.

To secure the purity of the minerals, the company shuns artificial ingredients and allergens, and it sells synthetic brushes with which to apply the makeup. For Bella Terra's beauty experts, the fuss is justified because at some point, they figure their products are going to touch someone's skin.
