Though we’ve been obsessively checking the forecast for heat and sun, sweaty days are rough on temperamental skin. Kiehl’s Rare Earth Deep Pore Mask (er, Masque) is a remedy for the blackhead-prone, especially if you’ve been running around outside. The creamy, fragrance-free mask is made of Amazonian white clay from Brazil, which draws out gunk and refines pores. Though a fair share of clay masks we’ve tried cause tightness or flaking, this one packs oatmeal and aloe vera to leave skin feeling soft. There’s an Earth Day–inspired incentive to try it this month: Chloë Sevigny and Michael C. Hall both designed limited-edition labels, with 100 percent of proceeds benefiting the Waterkeeper Alliance, a charity that protects waterways around the world from polluters.
