A mist spray is a type of skin care product that comes in the form of a liquid solution, usually water-based, that is sprayed onto the face using a misting bottle or atomizer. The main purpose of a mist spray is to hydrate, soothe, moisturize, relax, rejuvenate, and nourish the skin. Some mist sprays may contain additional ingredients such as sunscreen, minerals, vitamins, hyaluronic acid, or glycerin to provide additional benefits to the skin. Mist sprays can be used to:

• Hydrate the skin and maintain necessary moisture
• Soothe and calm irritated skin
• Refresh the skin after cleansing
• Prime the skin before applying serum, moisturizer, or SPF
• Set makeup
• Provide a midday pick-me-up
• Boost the effectiveness of sleep or sheet masks
• Balance the pH of the skin
• Protect the skin against harmful environmental factors such as dust and sunlight
• Care and protect the hair
• Provide aroma-therapeutic benefits
• Infuse the skin with positive skin-supportive ingredients like vitamin C, hyaluronic acid, and AHAs

Mist sprays are available in a variety of options, from organic to drugstore, and can be made at home using plain old H2O. While some researchers and consumers have questioned whether a product that is basically just a spray bottle filled with water is really worth the cost, many repeat buyers swear by them.
