You want to look for products with either benzoyl peroxide, an antibacterial that kills P. acnes, or salicylic acid, which breaks down blackheads and whiteheads while also sweeping away those dead skin cells. If you exfoliate, only do so once a week in order to avoid drying out or further irritating your skin. And Kenkare and Leger both agree that you can skip the toner, because it's an extra step that's not really necessary (and might even irritate you).
When you wash your face, Leger suggests a gentle face wash — one without scents or botanicals — followed by your spot treatment, and then a noncomedogenic moisturizer, and sunscreen if it's morning. If you wear makeup, of course that goes on last.
That said, Kenkare warns that acne products can dry out skin, and you don't want to overdry it or scrub too hard, because both can lead to irritation and more breakouts. So be gentle. Also, "don't try too many products at the same time — add them in gradually," she says, and when you do, test them on a small area first to see if they mess up your skin.
