Floral water (or hydrosol as it's also called), is the water produced during steam distillation of plant material. It contains water-soluble fragrance molecules and a very small amount of essential oil. It's great to use if you need a low concentration of essential oils or a low potency in general. With sensitive skin, products with a simple, thoughtful ingredient list are often best. It can also be helpful to avoid products containing harsh astringents and alcohol. That's where hydrosols come in. Gentle, alcohol-free toners can be hard to find on the shelves
