Where does this toner go in my routine?

Straight after cleansing, morning and evening, while the face is still damp. Anything thinner than a toner goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Sodium Hyaluronate and not three changes at once.

What else is on the list besides Sodium Hyaluronate?

Dipotassium Glycyrrhizate, Allantoin and Zinc PCA. The order they are printed in on this toner's panel is the order on the box, so you can see where Sodium Hyaluronate sits relative to them. Further down the same panel: Lactobacillus Ferment, Isoquercitrin and Quercetin.

Key actives

11Dipotassium Glycyrrhizateactive

Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is named eleventh on this toner's list, alongside Sodium Hyaluronate.

All products with Dipotassium Glycyrrhizate

17Allantoinactive

Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. The panel names it seventeenth on this toner's list, beside Sodium Hyaluronate.

All products with Allantoin

18Sodium Hyaluronatehumectant

Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it. It is the entry this toner is named after, and the list carries it.

All products with Sodium Hyaluronate

21Zinc PCAactive

Zinc PCA pairs zinc with the humectant PCA. It is used in oily and blemish-prone formulas for the look of shine and visible pores, and it hydrates at the same time. It is named twenty-first on this toner's list, alongside Sodium Hyaluronate.

All products with Zinc PCA

23Lactobacillus Fermentferment

Lactobacillus Ferment is the liquid left after lactobacillus bacteria have fermented a plant or milk substrate. It carries the small molecules the fermentation produced, including lactic acid and amino acids, and is used for the look of dull, uneven skin. It is named twenty-third on this toner's list, alongside Sodium Hyaluronate.

Anua Heartleaf 77 Hyaluronic Acid Soothing Toner (Renewed)

28 of 30 explained

Houttuynia Cordata Flower/Leaf/Stem Water (77%) plant extract: Heartleaf water, taken from the whole plant above ground. Korean formulas use it as a base in place of water, where it is far more dilute than the extract of the same plant.
Water solvent: Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
1,2-Hexanediol humectant: 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
Glycerin humectant: Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
Glycereth-26 humectant: Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
Betaine humectant: Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
Pentylene Glycol humectant: Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
Sodium Citrate pH adjuster: Sodium Citrate is the salt of citric acid, used as a buffer: it holds a formula at a steady pH rather than pushing it in one direction. It is also a mild chelator.
Isopentyldiol solvent: Isopentyldiol is a glycol used as a light solvent and humectant. It thins a formula, keeps extracts dissolved and leaves a dry finish.
Ethylhexylglycerin preservative booster: Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
Dipotassium Glycyrrhizate active: Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
Citric Acid pH adjuster: Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.

16 more explained

Acrylates/C10-30 Alkyl Acrylate Crosspolymer thickener: This is a carbomer relative with fatty side chains, so it thickens and stabilises an emulsion at the same time. It gives a light gel-cream body rather than a heavy one.
Tromethamine pH adjuster: Tromethamine neutralises acidic thickeners such as carbomer so they gel, and holds a formula near skin-friendly pH. It is used at a fraction of a percent.
Panthenol humectant: Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
Sodium Phytate chelator: Sodium Phytate is a rice-derived chelator used in place of EDTA. It ties up trace metals so the formula stays stable and its colour and scent hold.
Allantoin active: Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.
Sodium Hyaluronate (1.1ppm) humectant: Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.
Hydrolyzed Sodium Hyaluronate (100.1ppb) humectant: Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.
Zinc PCA active: Zinc PCA pairs zinc with the humectant PCA. It is used in oily and blemish-prone formulas for the look of shine and visible pores, and it hydrates at the same time.
Hydroxypropyltrimonium Hyaluronate (100ppb) humectant: Hydroxypropyltrimonium Hyaluronate carries a positive charge, and skin carries a slight negative one, so it is attracted to the surface and stays through rinsing. It is the hyaluronic used where a formula gets washed off.
Lactobacillus Ferment ferment: Lactobacillus Ferment is the liquid left after lactobacillus bacteria have fermented a plant or milk substrate. It carries the small molecules the fermentation produced, including lactic acid and amino acids, and is used for the look of dull, uneven skin.
Sodium Acetylated Hyaluronate (10ppb) humectant: Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
Isoquercitrin antioxidant: Isoquercitrin is quercetin with a glucose unit attached, which makes it far more water soluble than quercetin itself. It is used as a plant flavonoid antioxidant.
Quercetin antioxidant: Quercetin is one of the most widespread plant flavonoids, found in onion skin, apple peel and tea. It is a plant antioxidant and is yellow, so it tints a formula.
Hyaluronic Acid (2.5ppb) humectant: Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
Sodium Hyaluronate Crosspolymer (1ppb) humectant: Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
Potassium Hyaluronate (0.2ppb) humectant: Potassium Hyaluronate is another salt of hyaluronic acid, used for the same reason as the sodium form: it dissolves easily and holds a large amount of water in the outer layer of skin.

How it works

The Heartleaf 77 Hyaluronic Acid Soothing Toner is a 250ml toner, used straight after cleansing, morning and evening, while the face is still damp. The humectant it is built around is Sodium Hyaluronate, named eighteenth on its own ingredient list. The same list carries Dipotassium Glycyrrhizate, Allantoin and Zinc PCA, so the humectant is not the only thing on it worth naming. How much of the Sodium Hyaluronate stays on the skin, and for how long, is decided by the toner format rather than by the list alone. Anua sells this Sodium Hyaluronate toner in Korea, and this is that version.

How to use

Use the Heartleaf 77 Hyaluronic Acid Soothing Toner straight after cleansing, morning and evening, while the face is still damp.
Pour a coin-sized pool into your palms and press it over the face in two passes rather than dragging it around with a cotton pad.
It goes on before serum and moisturizer, and the damp layer it leaves is what the step above it holds on to.
Twice a day, every day. Do not let it dry down completely before the next layer goes on, or you lose the reason for applying it to damp skin.

Worth knowing

Patch test this toner on a small area and wait a day before using it more widely, especially with Sodium Hyaluronate on the list.
Introduce this toner on its own for the first week, so anything your skin does is traceable to the Sodium Hyaluronate rather than to three changes at once.

What professionals say

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.

Hyaluronic acid helps bind water to collagen, which traps water in the skin. That helps make the skin more plump and full-looking.
Samantha Stein, PA-CDermatology physician assistant, Cleveland Clinic
It contains liquiritin, an active compound that helps to disperse and remove existing melanin in the skin.
Jennifer Chwalek, MDDermatologist, Byrdie

1 more professional perspective

Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.
