When should we start using toners?
Overall, skincare experts recommend that people start incorporating toners into their skincare 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 skincare routine, you can visit and revisit them as skincare 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 skincare routine, a toner may help."
