Dermatologist seeks effective alternative to hydroquinone for hyperpigmentation

Carl R. Thornfeldt, M.D., has taken a fresh approach to an age-old dermatologic problem. "Where I practice in the high desert area, we have tremendous trouble with contact reactions to many skincare products and a lot of trouble with hyperpigmentation" in darker-skinned patients, who make up 30 percent of his practice. He is a Fruitland, Idaho, private practitioner and CEO and founder of Episciences.
