Overall, skin-care experts recommend that people start incorporating toners into their skin-care routine when it appears that their skin is getting oilier, whether that be due to puberty, hormone fluctuation, or environmental stresses. Rafaeloff mentions, "I recommend a toner should be introduced during puberty, when sebum and oil production are at their peak due to fluctuating hormonal levels."
Zeichner also noted that because toners are not an integral part of a typical skin-care routine, you can visit and revisit them as skin-care issues arise. "Just as you would select [other products in your routine], the same rules hold true with toners," he says. "If you feel that your skin needs an extra boost or you have hit a plateau [in] your traditional skin-care routine, a toner may help."
