Toners

The optional-but-lovely step between cleansing and serums. Today's toners aren't the harsh, stinging astringents of the past — they hydrate, calm and prep skin to absorb whatever comes next.

How to choose: sensitive or reddened skin loves a soothing, alcohol-free toner; dull skin benefits from a gently exfoliating or hydrating one. Sweep on with clean hands or a cotton pad after cleansing.
