Although I've been particularly attached to the Detox Cleanser and Detox Toner in this set, I argue that it's worth owning the entire four-piece Rapid Response Detox Kit ($132). Both the Triple Berry Smoothing Peel and Rapid Response Detox Masque are medicine cabinet staples for their acne-taming powers, but as of late, I simply can't go a morning without using the Toner and Cleanser duo. While the former uses salicylic acid and lactic acid to balance and smooth, the latter contains tea tree oil and kaolin to calm inflammation and unclog pores.
