Facial toners help to balance the pH level of your skin. pH levels are an indication of the acidity level of your skin and are measured on a scale of 0 to 14, with 7 being the most neutral level. Having a balanced pH level means your skin is less prone to oiliness and infection, creating a more vibrant and smoother appearance. Facial toners tighten your facial pores, allowing fewer oils and toxins to settle into the skin. This creates a fresher, cleaner and less oily appearance while preventing acne.
