Toners are an additional product to the cleansing routine. They are designed to remove any remaining residues left behind by your cleanser or face wash, and sweep away any lingering dead skin cells. They also help to tighten and refine the pores, making them less visible. Those who prefer toners tend to have either oily skin or dull skin. Toners are additionally used by some, to prepare the skin before applying a moisturiser.
