What Is Toner, and What Does It Do?

What does toner do? Depending on its active, it can remove residue after cleansing, add water to the skin, or gently shed dead skin if it contains an acid. But it is not a mandatory step; if you skip it, your routine is not incomplete. If your cleanser, moisturizer and sunscreen are in place, a toner is an optional addition. If you have rosacea, active acne or a barrier problem, it can bring dryness and irritation instead of benefit.

What does toner do, and what does it not do?

Toner is a mostly water-based, leave-on product used after cleansing and before moisturizer. Some of the benefits attributed to it are real, some exaggerated. The following table helps to filter marketing language:

Even with a toner that works, change is slow and often subtle. Talking about results without waiting between 6 weeks and 3 months is premature. The freshness felt after a single application does not show that the product is doing its job.

Types of toner: Look at what is inside the bottle

The name "toner" tells very little about the content. Products sold as toner, lotion or essence can differ greatly in their ingredients. The decisive factor is the ingredient list.

If you are thinking of getting an acidic toner, the AHA and salicylic acid pages help you understand what these actives do. For products containing AHA, it is useful to know an upper limit: an independent safety assessment found glycolic and lactic acid in consumer products safe at 10% or below, with a product pH of 3,5 or above, and with daily sun protection.

Which toner for which skin type?

• Dry skin: An alcohol-free, fragrance-free product containing hyaluronic acid and glycerin. Used only to add moisture; an acidic one is not needed.
• Oily skin: A soothing or light salicylic acid toner, instead of an alcohol-based astringent. Test it on the inside of your arm before starting.
• Combination skin: A moisture-focused product is enough. If you will use an acidic one, skip the dry areas.
• Sensitive skin: Often not necessary. If you want one anyway, choose one without heavy fragrance, dye or preservatives.
• Mature skin: Antioxidants such as vitamin C and ferulic acid together with moisturizing hyaluronic acid and glycerin are a good pair.
• Acne-prone skin: Here recommendations diverge. Some say toners containing AHA and BHA can help prevent clogging, but general dermatology advice is to avoid toners and astringents in acne. If you are under treatment, the cautious choice is not to add a toner.

Alcohol-containing or alcohol-free?

The source of confusion in this question is that the word "alcohol" covers several different substances. You need to separate two groups in the ingredient list:

• Drying alcohols: Written as ethyl alcohol, "alcohol," "alcohol denat." or SD alcohol. They can dry the skin and sting. If they are near the top of the list, they may make up a significant part of the product.
• Fatty alcohols: Cetyl alcohol, stearyl alcohol, cetearyl alcohol. Their effects on the skin are very different from ethyl alcohol. They can also be found in a product labeled "alcohol-free"; this is not a contradiction.

Older toners had high amounts of alcohol, and their drying nature came from that. Newer formulas are mostly gentler, but checking the list before buying is still necessary.

Some physicians say that a small amount of alcohol causes no problems on oily and acne-prone skin; on the other hand, dermatology advice recommending staying away from alcohol-based cleansers and astringents for this skin type is also common. With opinions this divided, the cautious choice is simple: if alcohol is at the top of the list, choose another product.

What else should you look for in the ingredient list?

Fragrance, essential oils such as mint, eucalyptus, lavender, tea tree, menthol, camphor and dyes are frequent causes of irritation on sensitive skin. The phrase "natural" or "herbal" does not remove this risk, as plant extracts can cause allergies.

When should you not use a toner?

• If you have rosacea. Astringents and toners are generally advised against in rosacea. Alcohol, menthol, camphor, glycolic and lactic acid are ingredients that can trigger flare-ups on this skin.
• If you have active acne. Toners and astringents can dry the skin and make acne look worse. If you use benzoyl peroxide or a retinoid, ask your doctor before adding a new product. For the reason behind acne, see the why acne forms article.
• If your barrier is weak. If there is stinging, flaking or tightness, it is not the time to add a product to the routine; first simplify.
• If you have eczema. Alcohols and acids can sting; consult your doctor before changing products.
• If your skin is very dry. Switching to a richer moisturizer is more useful than adding a product.
• If you use retinol and your skin is not used to it. Combined with an acidic toner, dryness and acne can increase.
• If you are just starting. A toner is not a first need. First spend a few weeks with a cleanser, moisturizer and sunscreen.

If you are pregnant or breastfeeding, ask your doctor before starting toners containing acid, and repeat the same question for other actives you use.

Rose water, witch hazel and apple cider vinegar

Rose water is often used in place of a toner, but reliable clinical data is very limited. Most of the research done is laboratory or animal study, and well-designed human studies testing regular use as a toner are almost nonexistent. If you like it and your skin tolerates it, you can use it for a refreshing feel, but do not expect it to lighten marks or reduce acne. If you have a plant or scent allergy, do a patch test first.

Witch hazel is used for the tightening effect of its tannins. One detail matters: distilled witch hazel water has almost no tannins, so water and extract do not do the same job. Mild irritation, redness and dryness are reported as side effects. Although allergic reactions are rare, they should be taken seriously.

As for homemade apple cider vinegar mixtures: the pH of apple cider vinegar is about 2,5, meaning it is much more acidic than the skin's own value. It can cause stinging, irritation and barrier damage. It is not something to use in place of a toner.

How is toner used?

1. Wash your face and pat dry. After the face washing step, the toner comes next.
2. Apply the product. If it is a spray, lightly mist your face; if it is liquid, pour it on cotton and glide it gently. Do not rub or massage.
3. Continue without rinsing. A toner is not rinsed off. Continue your routine with serum, moisturizer and, in the daytime, sunscreen. The details of this order are in the skin care routine order article.

How often?

In gentle, moisture-focused toners, 1-2 times a day is enough. If it contains a strong acid or other irritating actives, start every other day and increase according to your skin's reaction. When you see irritation or dryness, reduce the frequency, and stop altogether if needed. A patch test also works for a new toner: apply it twice a day to the inside of your arm or into the elbow crease, and watch for 7-10 days.

Toner and sun

AHAs can make the skin more sensitive to the sun. While using an acidic toner, and for a week after stopping it, take care with sunscreen, protective clothing and shade. If a toner is applied in the morning, sunscreen should be the last step.

Common mistakes with toner

• Using it in place of a cleanser. A toner is a continuation of cleansing; it should not be expected to take makeup and dirt by itself.
• Using it in place of a moisturizer. Even the most watery toner cannot lock water into the skin; do not skip the cream.
• Rubbing with a cotton pad. Rubbing irritates the skin. Glide the pad gently without pressing.
• Stacking acids. An acidic cleanser, an acidic toner and an acidic serum together in one routine bring dryness.
• Thinking stinging means it is "working." Stinging and burning are not a sign of effect; they are a sign of irritation. Stop the product.
• Expecting results in a week. Even if there is an effect, it comes slowly, over weeks.

Are toner, micellar water and essence the same thing?

• Micellar water is a cleanser. It contains small clusters of molecules that dissolve makeup and dirt, and it is used in the cleansing stage. Toner comes after cleansing.
• Essence is often confused with toners. Both are watery products, and the two terms are sometimes used interchangeably. Look at the content rather than what is written on the label.
• Astringent is mostly sold for oil control and is alcohol-based. Modern toners, on the other hand, are designed to refresh without removing the skin's moisture.

When does it make sense to add a toner?

If the product you have adds something for you, does not strain your skin, and your routine is otherwise well-founded, a toner is an option. It may be practical for those who want a light moisture layer in dry weather, or who want to work with a light acid a few times a week. Beyond this, if you think "I must buy a toner" to solve a problem, first review your cleanser, moisturizer and sunscreen. For redness, stinging or acne that does not go away, the answer is not a new bottle but a dermatologist's consultation.

If I don't use a toner, will my pores stay open?

No. Pore size is largely genetic, and a toner does not close it. When you stop the toner, no gap is created in your skin; your cleanser and moisturizer continue to do the same job.
