This is a light spray that aids in hydrating the skin. I definitely reccomend this for those with impaired skin barriers. How I use it is I use a soap free cleanser, or double cleanse with a balm (to remove sunscreen, excessive sweat from working out) then I spray this on a *damp* face. This is because hylarounic acid (which this product contains) is a humectant that holds moisture in the skin aka water. I then seal this with a moisturiser to prevent trans epidermal water loss. As if you don't seal this in, when the products dries it will draw moisture from your skin, as hylarounic acid tends to do this when it's not "sealed" it will just end drawing moisture from the deeper layers of your skin, drying it out further. This also contains panthenol which helps retain moisture and helps with skin healing and smoothing the skin. As I have just come off a very heavy prescription cream that has really damaged my skin, but this product helped tremendously, I hope that this review helps anyone deciding to buy this. I definitely think that's it worth a shot paired with a good moisturiser.
