Here’s What People Are Saying

Customer Reviews

“Switching over to Dr. Dixon’s topicals 20 years ago was a game changer for my business. Microcaine is pH of tears therefore no burning and as safe as tears! For eyebrows, I use Comort Cream or DOTC Blue as a pre-numbing, and I will go over with TAG#45 or Ultra Duration once the skin is broken. I won’t use anything else.”

“I ordered DOTC Blue specifically for use with a dermapen, a device that pokes 1000’s of tiny holes into the skin in order to stimulate collagen. After applying it for 20 minutes, I didn’t feel a thing. I had tried using the derma pen several times but couldn’t stand the pain. I am glad I found this!”

Dr. Linda Dixon, a retired anesthesiologist and dental hygienist, is a luminary in the medical and permanent makeup fields. Her journey began with her medical education at the University of Hawaii School of Medicine in 1969, followed by graduation from Loma Linda University School of Medicine in 1972. A pioneer in permanent makeup, Dr. Dixon’s quest started in 1979 with a request for eyeliner tattooing, a novel concept at the time. This experience fueled her dedication to developing pain control techniques in the field.

Dr. Dixon introduced the Dixon Technique in permanent makeup, revolutionizing the practice with efficient methods for creating rich lip colors, natural-looking eyebrow strokes, and smoky eyeliners. Her innovations extended to the creation of topical anesthetics, widely regarded as the industry standard, and the invention of the slope needle, a tool that enhanced precision in permanent makeup and tattooing.

Dr. Dixon’s impact includes her role in education, notably through the development of the Pain Control Exam for professionals. Her expertise was formally recognized when she achieved Board Certification in 1996 by the Academy of Micropigmentation, where she also served as President.

Dr. Dixon’s career is a testament to her commitment to improving lives through medical and cosmetic advancements.
