KolorSource™ pigments have their origin and safety track record since 1990 beginning with Helen Snow of Scottsdale, Arizona. Helen Snow is a beloved and respected permanent cosmetic professional and instructor since the early nineties. Helen takes a very practical and safe approach toward permanent makeup pigments. Helen knows from experience that colors change in the skin over time from exposure to sunlight to skin rejuvenating glycolic acids and Retin A and many other factors. Some colors, such as black, fade more quickly than others and in time procedures need to be refreshed. She also knows to avoid tattoo "inks" suck as Pelikan ink because they migrate or streak in the eyeliner and they get "blurry" over time in the brows.
