If an acid toner is what I need? I'm 39 with fairly dry / dehydrated skin which is a bit sensitive and can break out if irritated. Examples of this are heavy moisturisers, thick/siliconey foundations. Blackheads on nose, a few forehead lines but otherwise generally in good nick. Foundation/tinted moisturisers tend to dry out my skin after a few hours. Aim is to brighten and smooth my skin a bit, try and reduce the dry patches and even it out. Is an acid toner what i need??
