If the high temperatures are making you feel like Droopy, Tata Harper Hydrating Floral Essence, $85, will give you that much-needed hydration boost. This luxurious mist contains hyaluronic acid, a powerful humectant, and gotu kola, a plant that promotes circulation in the skin. Together, they give skin a full and plump (read: youthful) appearance. Spritz the mist on your bare face or over your makeup through the day to give skin a lift.
