Facial toners are a quick, easy skincare step. For optimal results, use toners twice daily after cleansing. Pour a small amount of facial tonic onto a cotton ball and smooth over the face, neck, and chest. If using skin toners in the morning, follow with a SkinCeuticals vitamin C serum and broad-spectrum sunscreen. When using facial toners in the evening, follow with a SkinCeuticals corrective serum or moisturizer.
