Toners do not physically close pores, but they can help to make them look smaller temporarily. Toners can contain ingredients that exfoliate the skin, such as alpha-hydroxy acids (AHAs) and beta-hydroxy acids (BHAs), which can help to remove dead skin cells and impurities that can contribute to pore enlargement. Salicylic acid is an oil-soluble BHA that can penetrate the trapped sebum and impurities within pores, deep-clean them, and reduce their apparent size. Some toners contain salicylic acid and other skincare acids that can speed up the natural exfoliation rate of the skin, reduce redness, and hydrate.
In summary, toners do not physically close pores, but they can help to make them look smaller temporarily by exfoliating the skin and removing impurities. Toners can contain ingredients such as salicylic acid that can deep-clean pores and reduce their apparent size.
