Toners are beauty products that help to balance the skin's pH levels, clean out any dirt or impurities, and tighten pores. Some common synonyms for toners includes astringents, mists, facial tonics, and hydrosols. Astringents are a type of toner that are typically alcohol-based and help to reduce oil and prevent breakouts. Mists and facial tonics are similar to toners in that they hydrate and balance the skin but often have added skin-boosting ingredients. Hydrosols are also known as floral waters, and are natural toners made from plant extracts. Whatever synonym is used, toners are an important part of a skincare routine for their ability to leave the skin feeling fresh and clean.
