What toners were meant to do
Toners started out as astringent liquids, often alcohol-based, used after washing to remove the last traces of cleanser and leave the skin feeling tight and fresh. Modern toners are usually gentler. Many are simply watery liquids meant to rinse away residue, add a little moisture or deliver mild ingredients before moisturizer.
A face mist is similar in concept but sold in a spray bottle. People use mists to feel refreshed during the day, or to dampen the skin before applying oil or cream.
Neither is essential. A person with comfortable skin who cleanses gently and moisturizes may get nothing noticeable from a toner. Whether it is worth having comes down to whether you like the feel and your skin tolerates it.
What a toner can and cannot do
Possible benefits are modest:
- Removes leftover cleanser or mineral residue, particularly in hard-water areas
- Leaves the skin lightly damp, which helps with moisturizer application
- Feels refreshing, especially when chilled
- Adds a mild, pleasant fragrance if one is used
Things a toner cannot do: shrink pores permanently, balance skin, cure acne, or “close” the skin. Pore size is mostly fixed by genetics, a point explored under enlarged pores.
Astringent toners: a caution
Toners that contain a lot of alcohol, witch hazel with alcohol, vinegar or citrus can feel clean but leave many skin types dry and tender, and the more sensitive a face is, the more likely it is to react. People with sensitive skin care needs, rosacea-prone skin or eczema prone skin generally do better with the mildest possible liquids, or none at all. Apple cider vinegar toners, often shared online, are a common source of irritation and are not a good idea if you are unsure about strength.
What hydrosols are
A hydrosol, sometimes called a floral water, is the water left over when plant material is steam-distilled to make an essential oil. It contains tiny amounts of the plant’s aromatic compounds, which gives it a gentle scent. Rose, lavender and chamomile are common examples.
Hydrosols are much weaker than essential oils, and many people tolerate them well, though they are not guaranteed harmless. Allergies to the plant are still possible. They differ from essential oils in two important ways:
- They are mostly water, so the concentration of aromatic compounds is far lower.
- Because they are mostly water, they can spoil. Many are sold with a preservative or must be refrigerated and used quickly.
Do not confuse a hydrosol with essential oils diluted in water. Oil and water do not mix, and drops of essential oil floating in a spray bottle can land undiluted on the skin or in the eyes.
Why homemade water-based toners spoil
Any product containing water can grow bacteria, yeast and mold, often without obvious signs at first. This is why product spoilage is the main risk of DIY toners and mists. A bottle left on a bathroom shelf, opened repeatedly and exposed to warm air, is an ideal setting for contamination.
If you make water-based products anyway:
- Use distilled or boiled-and-cooled water, and sanitize bottles and tools first, following the steps under sanitizing equipment.
- Make very small batches and keep them refrigerated.
- Discard after a few days, or sooner if the liquid becomes cloudy, develops a smell or changes color.
- Learn about skincare preservatives before attempting anything you want to keep longer. No preservative amount should be guessed at.
Because of these concerns, many careful makers skip DIY toners entirely or rely on products with a reliable preservative system.
Simple alternatives
- Plain water. A splash of cool water after cleansing does much the same job as many toners.
- A damp cloth. A clean damp cloth can remove cleanser residue.
- A bought hydrosol or mist. If you like the idea, choose one from a trustworthy source that lists its ingredients and preservation method. Reading ingredient lists helps you spot alcohol or added fragrance.
- Chilled green or chamomile tea. Some people dab it on, but brewed tea spoils within a day or two, even refrigerated, and is not a product for storing.
Using a toner or mist
- Cleanse and pat dry.
- Apply a small amount to a cotton pad or spray with your eyes closed, holding the bottle at arm’s length.
- Allow it to sink in, then apply moisturizer or oil while the skin is still slightly damp.
- Stop if there is stinging, redness or itching.
Use a patch test before putting any new liquid on your face. Fragrance sensitivity is common, and floral waters carry the scent of the plant.
Do you need one?
Probably not, and that is fine. If your routine is cleanse, moisturize and apply sunscreen, adding a toner brings small returns and a bit more to go wrong. If you enjoy a cool mist on a hot day and you have a safe, stable product, it can be a harmless pleasure. If your skin becomes irritated, drop it first.
