GSR stands for “Getting Skin Ready” for a ZO Skin Health skincare regime. All patients are advised to start with the Daily Skincare Program for at least two weeks to prepare the skin for targeted concerns without increasing skin sensitivity. As a medical skincare range, many of the products contain high-strength ingredients that skin needs to be prepared for. Hence, GSR is essential when commencing a ZO skincare regime, meaning that these products should be used on a daily basis to maintain your skin. These products include a cleanser, exfoliator, and daily power defence with retinol. Without the application of these products, you won’t be able to achieve optimal results via your skin treatment.
