RX Skin Therapy - RX Skin Therapy was created by Kristen Riddle, PharmD, after years of compounding problem-solving products with patients and physicians. She began to manufacture and market RX Skin Therapy after seeing clinical successes with her patients. Today, the line includes 18 products intended to improve the appearance of aging skin. They include cleansers, facial masques and exfoliants, moisturizers, and anti-aging and skin-rejuvenation products. Because the formulations are science-based and contain medicinal percentages of cosmeceutical ingredients and botanicals, the products are significantly different than most similar products, which often include only trace amounts of these expensive ingredients and botanicals.
