A Secret From Decades of Dental Innovation.
For millions of years, the sun has solved a problem: dampness fuels bacteria and fungi. Every surface exposed to its ultraviolet light is sterilized — no chemicals, no residue. It's nature's most potent disinfectant, proven across every ecosystem on Earth. Korina specialists discovered this decades ago. Long before consumer gadgets existed, they used UV-C light in operating rooms to sterilize surgical tools and purify air. It was simply how things were done.
Finally, From the Hospital to Your Home.
Dr. Michael Trent, a board certified physician from Boston, MA, spent years watching hospitals use UV-C light to sterilize surgical tools. When he saw families at home brushing with germ-covered, bacteria-coated bristles, he knew he had to bring this technology to the bathroom counter. Korina is that technology — brought to you.
