Since 1980, Dermatologic Cosmetic Laboratories (DCL) has provided physicians with the highest quality non-prescription skin and hair formulations for direct dispensing. For over two decades DCL scientists and chemists have worked closely with dermatologists to develop the most innovative and effective formulations using only the highest pharmaceutical grade ingredients. In 1988, DCL was one of the original pioneers in the cosmetic use of Alpha Hydroxy Acids. The wide range of protocol products includes an extensive selection of AHA formulations and forms including creams, lotions and gels containing increasing concentrations of Glycolic Acid for “step-up” dispensing.
