There are two main benefits of facial mist sprays -- they can temporarily change the appearance of your skin, and, since they're usually cool and pleasantly fragranced, they can help you feel good. Some sprays are marketed as being able to temporarily give you a dewy glow if your skin is feeling dried, and others designed by cosmetic companies may help set or refresh your makeup. Keep in mind, though, that many of the ingredients added to sprays can't actually be absorbed by your skin. So, while a mist might set your makeup or brighten your face for a little while, it's not going to make a lot of physical improvements to your skin.
Aromatherapy, the use of essential oils extracted from plants, might be another reason to use a facial mist spray [source: Hawkins and Ehrlich]. Many alternative medicine practitioners say certain scents can be effective against depression, anxiety, insomnia or exhaustion, although in some cases scientific evidence is inconclusive. If you choose a facial mist for this reason, be sure to read the ingredients list carefully. Several essential oils, such as cinnamon, can cause irritation or breakouts when applied to the skin.
Be careful about overusing facial sprays. When you mist your face, the water evaporates, which can dry your skin -- think of the way your lips become chapped if you lick them too often. Also, some added ingredients might dry your skin out by stripping away the protective layer of oil, or sebum. If you find a spray that contains moisturizer or if you moisturize shortly before or after you spritz, you can help guard your skin's moisture level. Also, keep in mind that, although a sunscreen-containing mist is probably better than no sunscreen at all, a mist might not cover your skin thoroughly enough to really protect you from the sun.
