Skin toners can be beneficial in improving the appearance of acne scars, although they might not directly treat the scars themselves. Acne toners often contain ingredients like glycolic acid, salicylic acid, or witch hazel, which have exfoliating and astringent properties. These ingredients can help unclog pores, remove dead skin cells, and promote skin renewal, which, over time, can contribute to a smoother skin texture and a reduction in the visibility of certain types of acne scars. Pore reducing toners also work on minimizing the appearance of pores.
Additionally, acne toners contain antioxidants and soothing agents like chamomile or green tea extract, which can promote overall skin health and minimize redness or inflammation associated with acne scars. However, for more severe or deep acne scars, it's best to consult a dermatologist who can recommend appropriate treatments to address specific scar types effectively.
