At $45 a pop, this mask is a splurge, but Upton swears by it as “one of [her] favorites.” Knesko was founded by Reiki master Lejla Cas, who wanted to merge mainstream skin-care with energy work and gemstones. (The products even get charged with Reiki energy before they’re shipped out.) Aside from the energy-healing perks, this mask incorporates hyaluronic acidniacinamide, and gold for anti-aging benefits.
