Personally, I love toner — use it twice daily after cleansing. Toner is a pH regulator, so it’s essential for closing pores, removing last traces of dirt & cleanser, and putting skin back into its “happy place”! But you’ve got to use one that doesn’t contain solvent alcohols, which dry the skin and contribute to scarring on damaged skin. You will also get more mileage out of your moisturizer if you are using a well made toner, because skin absorbs moisture more effectively when it is at its correct pH (between 5.5 and 6.5). Drier skins need more of a skin freshener rather than a toner (designed for normal to oilier skin). Look for high-quality toners with no added color or perfume, no SD Alcohol 40, and no feeling of tightness after applying.
