What does toner do?

Toners serve a purpose and most people don't bother to use them.  Toners act as a second and final step in your cleanse.  They remove any excess dirt, sebum or makeup that your cleanser may have left behind. More importantly, they keep your skin pH balanced.    

Cleansers naturally throw off the pH balance of your skin and toners help bring it back immediately.  If you have oily/acneic skin, an astringent toner would be best suited for you.  If you have normal/dry skin, a hydrating toner would be best.  I love the toner by Dr. Alkaitis!  If you have really sensitive skin or rosacea, rose water is for you.
