March 6, San Francisco – Merz Aesthetics, a division of Merz Pharmaceuticals USA, introduced The Merz Scales – the first standardized, comprehensive rating system that measures and helps educate physicians, researchers and patients on the skin’s aging process – at the American Academy of Dermatology’s (AAD) 67th annual meeting in San Francisco. Developed by a leading team of multidisciplinary experts, the Merz Scales address the need for standardization, validation, and consistency when evaluating changes in aging skin. While the scales do not diagnose or treat any particular conditions, they do facilitate education and communication between physicians and patients about the aging process.
