The Merriam-Webster Dictionary defines toner as “a liquid cosmetic for cleansing the skin and contracting the pores.”
According t0 TheGloss.com there is some discrepancy between whether “toner” and “astringent” are interchangeable. Astringent was a term popular in the late 90’s and early 2000’s and generally meant products that were used to treat acne and absorb oil. Astringents were thought to be stronger than toners, and they were usually alcohol or chemical-based. Just to confuse us even more, there’s no definitive guide because some astringents are alcohol-free and the term seemed to fall by the wayside, in favor of toner.
“Toner has become the key word over astringent in the new millennium. Toners range from gentle witch hazel to rose water, repairing, hydrating, restoring and balancing ph. The right toner can give your skin the boost it needs to stay healthy, younger, fresher, and clear from excess oil. CL Skin has the right Toner for you”
