If you have oily skin, you'll want to look for a highly absorbent, talc-free setting powder that keeps shine at bay. Those with combination skin types can use a similar formula, though they may only want to apply the powder to shinier areas. As Zeinali notes, "People are normally the oiliest in their T-zone." If your skin is on the drier side, or you prefer a dewy finish, opt for a setting powder with hydrating ingredients, like hyaluronic acid. It sounds like an oxymoron, but a powder can be both absorbent and moisturizing at the same time.
