Toners primarily balance the skin's pH after cleansing, preparing it for better absorption of subsequent skincare products like serums and moisturizers. They can also help remove residual impurities and oils, depending on the formulation.

The best toner depends on your skin type. Look for hydrating toners with ingredients like hyaluronic acid for dry skin, exfoliating toners with AHAs/BHAs for oily/acne-prone skin, and soothing toners with ingredients like aloe vera for sensitive skin.

Dermatologists may recommend toners, particularly for specific skin concerns. Their recommendations often depend on the ingredients and whether they address individual needs like acne, dryness, or sensitivity, while avoiding harsh ingredients like alcohol.

While categories can overlap, toners are broadly classified as hydrating (focus on moisturizing), exfoliating (contain acids to remove dead skin cells), and clarifying (target oil and impurities). It's important to choose one that matches your skin type and concerns.
