The new Obagi C Rx complete system is the first and only prescription strength skin care system that combines 4 percent hydroquinone and professional strength vitamin C. The vitamin C in the Obagi has been shown to improve elasticity and firmness, protect the skin from the environment, and prevent the appearance of skin aging. Hydroquinone decreases the formation of melanin in the skin. Melanin is the pigment in the skin that gives it a brown color. To gradually lighten areas of darkened skin such as freckles and age spots, apply the Obaqi system.
