Skin loves beautiful color Our pigment colors meet federal quality standards and are made with FDA approved ingredients for cosmetic use and are continuously submitted to laboratory testing. As we mentioned earlier the pigments are color stable, non toxic and do not cause skin irritation. Since we use mostly non-organic color pigments for the implantation, side effects can definitely not occur, meaning that no cancerous substances will remain in the skin. What will remain is beautiful color which will last several years and fade naturally.
