Toners are applied after cleansing to balance the skin's pH levels and prepare it for subsequent treatments. They often contain ingredients like antioxidants, hyaluronic acid, and soothing agents, delivering hydration and refining pores. Toners help remove residual impurities, restore the skin's natural pH, and enhance the absorption of serums and moisturizers. With regular use, toners contribute to a smoother, more even complexion and can be tailored to different skin types and concerns.
