How it works
Betula Platyphylla Japonica Juice leads the ingredient panel on this toner. Betula Platyphylla Japonica Juice is Asian white birch sap, tapped in spring. It is over 98 percent water with trace minerals and sugars, and Korean formulas use it in place of plain water as a hydrating base. On this panel it sits alongside Dipotassium Glycyrrhizate, Allantoin and Portulaca Oleracea Extract. 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.
Key benefits
- Betula Platyphylla Japonica Juice named on this product's own ingredient panel, near the top of it
- Dipotassium Glycyrrhizate on the same panel, the formula's active
- Allantoin on the same panel, the formula's active
- 200 ml to a unit
- Korean-market formula, with its Korean barcode and batch code intact on the box
How to use
- Use Round Lab For Men Birch Juice Moisturizing Toner 200ml morning and night. Apply two to three pumps in the palm, or poured onto a cotton pad, pressed or patted into clean, damp skin. It goes first among your leave-on steps, right after cleansing and before any essence, serum or moisturizer.
Is this the same formula sold in Korea, or a version made for the US market?
This is the Korean-market formula, the same one sold on shelves in Korea, not a separate version reformulated for US retail. The pack you open matches what a shopper in Seoul buys.
Where does this step go in a routine?
It belongs first among your leave-on steps, right after cleansing and before any essence, serum or moisturizer. Placing it earlier or later than that changes how it feels going on and how well the steps after it absorb, so keeping it in that order is worth doing even on a simplified routine.
Can I use this if my skin runs sensitive?
This toner is formulated with skin types like normal skin, dry skin in mind, but any new product is worth a patch test first if your skin reacts easily. A short patch test on the inside of your arm or behind an ear is worth doing with any new product before it goes on your face, and that goes for sensitive skin most of all.
How long before I will know if this is right for my skin?
Give it a full week or two of consistent use before judging, since a single use rarely tells you much either way. Watch for how skin feels rather than for any specific number, and stop use if you notice ongoing irritation.

30 of 30 explained
- 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.
- Butylene Glycol humectant
- Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
- 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.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- Dipropylene Glycol humectant
- Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
- Betula Platyphylla Japonica Juice plant extract
- Betula Platyphylla Japonica Juice is Asian white birch sap, tapped in spring. It is over 98 percent water with trace minerals and sugars, and Korean formulas use it in place of plain water as a hydrating base.
- 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.
- Glyceryl Glucoside humectant
- Glyceryl Glucoside is glycerin bound to glucose, from the resurrection plant. It is a humectant that holds water in the outer layer of skin.
- 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.
- 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.
- Portulaca Oleracea Extract plant extract
- Portulaca Oleracea is purslane. Its extract is unusually high in omega-3 fatty acids and antioxidants for a plant, and Korean formulas use it for the look of reddened, reactive skin.
- Sodium Hyaluronate 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.
18 more explained
- Hyaluronic Acid 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.
- Ascorbic Acid antioxidant
- Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone.
- Diospyros Kaki Leaf Extract plant extract
- Diospyros Kaki is the persimmon tree. Its leaf extract carries tannins and vitamin C and is used as an antioxidant extract.
- Vitis Vinifera (Grape) Fruit Extract plant extract
- Grape Fruit Extract carries polyphenols and fruit acids. It is used as an antioxidant plant extract.
- Polygonum Cuspidatum Root Extract plant extract
- Polygonum Cuspidatum is Japanese knotweed, the main commercial source of resveratrol. Its root extract is used as an antioxidant plant extract.
- Coffea Arabica (Coffee) Seed Extract plant extract
- Coffee Seed Extract carries caffeine and chlorogenic acid. It is used as an antioxidant extract and, in eye and body formulas, for the look of puffiness.
- Carthamus Tinctorius (Safflower) Flower Extract plant extract
- Safflower Flower Extract is a traditional East Asian dye and skincare plant. It is used as a conditioning antioxidant extract and can tint a formula.
- Castanea Crenata (Chestnut) Shell Extract plant extract
- Chestnut Shell Extract carries tannins and is used as an antioxidant plant extract, most often in formulas aimed at visible pores.
- Camellia Sinensis Leaf Extract plant extract
- Camellia Sinensis is the tea plant. Green tea leaf extract carries catechins, among the most studied plant antioxidants, and is used for the look of redness and oily shine.
- Gluconolactone exfoliant
- Gluconolactone is a PHA, the gentlest exfoliant class. Its molecule is too large to penetrate quickly, so it smooths the surface without the sting of an AHA, and it is a humectant at the same time.
- Tocopherol antioxidant
- Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
- 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.
- Xanthan Gum thickener
- Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
- Glyceryl Caprylate emulsifier
- Glyceryl Caprylate is a mild emulsifier that also makes a formula less hospitable to microbes, so it is often part of a preservative-free system.
- Dextrin thickener
- Dextrin is a starch fragment used to thicken and to give a formula a light, powdery finish. It is also a common carrier for powdered extracts.
- Gardenia Florida Fruit Extract plant extract
- Gardenia Fruit Extract is the traditional East Asian yellow dye plant. In skincare it is used as an antioxidant extract, and it can tint a formula.
- 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.
- Disodium EDTA chelator
- EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.

Worth knowing
- Pat the toner in with palms rather than dragging a cotton pad hard across skin, since friction rather than the formula is what irritates sensitive skin.
- Layer a serum or moisturizer over it while skin is still slightly damp, since a toner alone is not built to be the last step.
