Using a toner after cleansing has a variety of benefits for the skin.
In addition to removing any dirt, debris, and excess oil that remain after washing, facial toners with hydroxy acids can help exfoliate the skin.
This extra exfoliation removes the uppermost layer of dead skin cells to help promote the absorption of the skin care products that follow.
Eliminating these dead, dull cells with a facial toner helps enhance the skin’s radiance, smooth surface texture, and promote
healthy-looking complexion as well.
A facial toner, especially those with witch hazel or hydroxy acids, is especially useful for those with 
oily 
or 
acne-prone skin, as this extra step helps reduce the excess oil and dead skin cells that can clog
pores and lead to breakouts.
Some facial toners can help maintain the skin’s pH balance, which is associated
with optimal skin-barrier function. A primary role of the skin’s barrier is to help the skin retain moisture. In those with dry skin, a toner may
help improve flaking and the appearance of dullness.
