Astringent or Toner?

Astringent
An astringent is usually stronger than toner & is alcohol & chemical based. This gives it anti-bacterial properties. Usually recommended for acne prone skin or extremely oily skin. Astringents destroy bacteria, help control oil, acne breakouts, pimples, & blackheads. Astringent use on a lesion due to acne or a pimple may cause a stinging sensation, which is pretty normal.

Remember to always use your toner or astringent after cleansing & before applying your moisturizer.
