Hydrating mists, on the other hand, are filled with moisture-binding ingredients that ensure the mist particles hug the face and infuse your pores with the good stuff. In fact, using a hydrating mist before you apply your serum and moisturiser can actually help your products penetrate deep into the dermis. It doesn’t hurt to mist in between your make-up steps, either, before and after primer, foundation and powder, helping the layers to blend into each other more seamlessly. If you have oily skin, misting regularly helps your skin stay hydrated and controls compensatory sebum production.
