Toners are grouped into three categories they are skin bracers or fresheners, skin tonics, and astringents. A skin bracer is the mildest as it contains water and glycerin (a humectant). A good example of a skin freshener would be rose water and best suited for dry skin. Skin tonics are a bit stronger and have a small amount of alcohol. They are best suited for combination skin, normal skin and oily skin. Lastly astringents such as Witch Hazel are the strongest of toners and can contain up to 60% alcohol.

Thus astringents are best used for spot treatments only.
