Arithmetic Acne Control Complex
"I usually stick to organic products, but my history of troubled skin sometimes comes back with a vengeance. During severe breakouts I turn to Arithmetic's Acne Control Complex, which unlike other benzoyl peroxide products keeps skin moisturized. Plus, in lieu of most harmful ingredients (parabens, sulfates, fragrances and phthalates), the formula uses tea tree oil and witch hazel, which treats oiliness, inflammation and appeases my green inclinations."—Kristina Rudolfo, Associate Editor
