BioTouch pigments are formulated with Iron Oxides which are known to be safe for cosmetic use, colorants, and micropigmentation to the face and body. Because our pigments have more of these particles in every drop, they absorb into the skin much more effectively. The result is less fading, and truer color.Our pigments also have a different texture and quality. They do not dry out like most. The microfine particles used, along with Ethanol, allows the pigment to dry slower, and keeps the mixture smooth, as the technician works with it. Other brands of pigments boast to have organic compounds, but organic is not always the best choice. Allergies can be more common inorganic substances. Some people are allergic to vegetable dye, and pigments with vegetable dye are not stable. Some brands even use industrial colors similar to automobile paint! This can be dangerous and can cause an allergic reaction. In addition to iron oxides, our black shades are carbon-based, which has the same chemical makeup as what is naturally found in our bodies, so there is even more precaution against any chances of an allergic reaction.
