(MONEY Magazine) – Our organization, which is composed entirely of clinical dermatologists, had occasion to critically review your article on ''The Selling of Retin-A'' (April).

The promotion of prescription drugs directly to the public and the increasing confusion between marketing efforts and the dissemination of scientific data are particularly deplorable. Philip M.
