Dry air can exacerbate skin conditions like roughness, dryness, senile age related dryness, atopic dermatitis etc. It becomes very important to then ensure enough hydration throughout the day. Facial mists help to hydrate the superficial layers of the skin during the day while also providing nutrients. Also they help to prevent transepidermal water loss and hence drying of the skin. The increased hydration increases the softness of the skin and distension. Also facial mists contain antioxidants, aloe vera, vitamin c, green tea etc. which have many beneficial properties.
However the contents of the mist play a critical role. It is best avoided when they contain preservatives and alcohol which tend to irate the facial skin. Also avoid mists that contain formaldehyde, parabens or synthetic fragrances. Also overuse of mist over a long period of time can create a scaly texture. Correct usage and environmental conditions also are important. The use of mist is most beneficial during summers and in air conditioning environments while using mists during monsoon can lead to skin becoming greasier. Also use in extremely cold environments can over dry the skin. Also most skin types can benefit from facial mist but for sensitive skin its best to select spring water or a hypoallergenic version of mist.
