All our pigments are cosmetic grade, which means that they are sterilized and purified for cosmetic use. All of the ingredients have been approved by the FDA for cosmetic use. Be wary of products that have not met safety standards, including those that contain “vegetable dyes” that are unstable and may change color over time. In addition, all our tools are sterilized, single use needles, and they are discarded after the treatment. Our specialists are highly trained, experienced professionals, and licensed by NYS Department of State, Division of Licensing Services.
