Facial sprays are widely sold and widely misunderstood, and the honest position is modest.
What Water Does
Water on skin evaporates. As it does, it can take moisture with it, which is why plain water alone does not hydrate skin and can leave it feeling tighter afterwards.
That is the substance of the criticism of plain water misting, and it is broadly correct.
Applying a moisturiser to damp skin, however, helps that product seal water in, which is where the useful version of this sits.
What a Mist Is Genuinely For
- Damping skin before applying a moisturiser or serum
- Refreshing in heat, which is comfort rather than skincare
- Reactivating and blending makeup
- Applying a toner evenly without a cotton pad
- Setting sprays, where the product itself does the work
Travel-size misters, of the kind catalogued at https://flairosol.us.com/, deliver an even fine layer, which matters for distribution rather than for what the liquid contains.
The Ingredients Do the Work
Any effect beyond wetting comes from what is in the bottle rather than the mist itself.
Humectants such as glycerin attract water. Occlusives hold it in. Water on its own does neither.
A mist is a delivery method, not an active.
Hygiene Matters Here
Worth being specific about, because this is sprayed at a face.
Water and home-made mixes left in a bottle for weeks grow microorganisms, particularly with anything organic added.
Make small quantities, keep them cool, use them within days, and wash the bottle regularly. Cloudiness or a musty smell means discard it.
Eyes and Broken Skin
Avoid spraying anything but plain water near open eyes, and avoid broken or irritated skin entirely.
Persistent Skin Problems
Warrant a pharmacist or a doctor rather than another product.

Plain water plus a moisturiser is most of it.
