What is considered the strongest acting type of toner?

The strongest acting type of toner is recognized as the astringent. Astringents contain higher concentrations of alcohol or other active ingredients that tighten and tone the skin. They are particularly effective for individuals with oily or acne-prone skin, as they help to remove excess oil and minimize the appearance of pores. The action of astringents can lead to a more refined skin texture and a reduction in shine, making them suitable for those seeking strong results in oil control and skin clarity.

In contrast, moisturizing toners are designed to hydrate and soothe the skin, exfoliating toners gently slough away dead skin cells to promote a smoother complexion, and hydrating toners primarily focus on adding moisture without the tightening effects characteristic of astringents. While all these types have their benefits, astringents stand out for their strong, immediate tightening and oil-controlling properties.
