How often should I use a toner on my face to achieve optimal skin health? Is it necessary to incorporate toner into my daily skincare regimen, or should it be reserved for specific occasions, such as post-exercise or after cleansing? With the myriad of toners available—ranging from hydrating and soothing formulas to those designed to clarify and exfoliate—what is the ideal frequency for each type? Moreover, considering factors such as my skin type—be it oily, dry, or combination—could these variables influence how often I should apply toner? Should I perhaps use it once in the morning and once at night, or might it be sufficient to limit its use to a few times a week? Additionally, if I’m using other active ingredients in my skincare routine, how would that interplay with my toner usage? Do I need to be cautious of over-exfoliation or irritation? What is the consensus among dermatologists regarding this pivotal question?
