Hydrating Toner

Hydrating Toner — a water-based liquid applied after cleansing to add lightweight moisture and help prepare skin for the products that follow. It typically relies on humectants such as glycerin or hyaluronic acid to draw water into the upper layers of skin, leaving it feeling soft and replenished rather than tight.

Key points

  • It focuses on adding hydration rather than exfoliating, so it contains no or minimal acids.
  • Typical ingredients include glycerin, hyaluronic acid, panthenol, and soothing botanical extracts.
  • It is often patted on with the hands or a cotton pad immediately after cleansing while skin is still slightly damp.
  • Because it is gentle, it can generally be used morning and evening and suits most skin types, including dry and sensitive skin.

Frequently asked

What is the difference between a hydrating toner and an exfoliating toner?

A hydrating toner adds moisture and soothes the skin, while an exfoliating toner uses acids to remove dead surface cells. They serve different goals and can be used at different times in a routine.

Do I need a hydrating toner if I already use a moisturizer?

It is optional, but a hydrating toner can add an extra layer of lightweight moisture and help subsequent products spread evenly. Skin that feels adequately hydrated may not need one.
