The seaweed powder in Bliss No 'Zit' Sherlock Breakout-Busting Rubberizing Mask (
$38 for six, blissworld.com) penetrates pores to dissolve excess dirt. Tea tree oil treats existing blemishes and helps prevent future breakouts, and menthol and willow extracts reduce inflammation. When the mask turns rubbery, 15 to 20 minutes after you apply it, slowly peel it off.
