Every type of skin regimen can benefit from a weekly treatment to complement the usual routine of daily products. MD Formulations Masks offer an additional step to give the skin a boost that it does not ordinarily receive on a daily basis. Depending on the need, MD Formulations Masks can offer a deep cleansing, additional moisture, firming or brightening effects. All MD Formulations Masks are intended to be used with a daily regimen from MD Formulations. None of the MD Formulations Masks should be considered a replacement for the essential daily products in a healthy skin care routine and should always be followed by an appropriate moisturizer and/or treatment product.
