How it works
This is the gel in Round Lab's Birch line, the lightest way the brand closes a routine, and it is aimed at skin that wants water without weight. Birch sap sits in a base of hyaluronic acid, sodium hyaluronate and glyceryl glucoside, with aloe leaf extract and a run of plant extracts on the calming side. A gel like this absorbs in seconds and leaves nothing tacky, so it works under sunscreen in the morning and on its own on a humid night. Oily and combination skin can use it as the whole moisturizer step, while dry skin is better off putting it under a cream. Use it as the last step of the routine, and again through the day whenever skin feels tight.

Where each key active sits on the declared ingredient list, by entry number. Position is proportion: the further forward, the larger its share.
How to use
- Use the Birch Moisturizing Soothing Gel as the last skincare step, morning and evening, over serum.
- A generous fingertip for the whole face. It spreads further than a cream, so start with less than you think.
- Serum first, this second. In the morning it is the layer sunscreen goes over, so give it a minute to settle first.
- Twice a day, every day. Do not layer it under a heavier cream to get more out of it; two lids in one routine only slow the first one down.
Round Lab Birch Moisturizing Soothing Gel 150ml
What does the Birch Moisturizing Soothing Gel 150ml actually do?
Hyaluronic acid and glyceryl glucoside round out the moisture side, while a five-plant soothing blend of aloe, laminaria, viola mandshurica, ulmus davidiana, and dioscorea japonica gives the gel its cooling, non-sticky finish. The 150ml tube is meant for generous all-over use on face, hair, or body, and some people keep it in the fridge for an extra cooling effect after a day outdoors. Betula Platyphylla Japonica Juice and Aloe Barbadensis Leaf Extract are the actives carrying that job on the ingredient list, not a marketing name alone.
Can I use the Birch Moisturizing Soothing Gel 150ml every day, morning and night?
Any step after cleansing, face or body. Spread a generous layer where skin feels warm or tight; keep it in the fridge for a stronger cooling effect. Nothing on the ingredient list is a resurfacing or exfoliating active, so this is meant for both routines every day rather than a once-a-week treatment.
Can I layer the Birch Moisturizing Soothing Gel 150ml with a retinoid or an exfoliating acid?
Yes, and there is nothing on this ingredient list that competes with one. It carries no retinoid and no exfoliating acid of its own, so it slots in as a hydrating or barrier step around an active from a separate product rather than working against it.
What does the Birch Moisturizing Soothing Gel 150ml feel and smell like on skin?
It applies as light watery gel, absorbs without film. No added fragrance on the ingredient list. For reactive or easily-irritated skin, patch test on the inner arm a day ahead of putting a new step on the face.
Is this the same formula sold in Korea, or a US version made for this market?
This ships as the Korean-market formula Round Lab sells in Korea, not a US-shelf reformulation. Its Korean barcode and batch code stay on the box rather than being replaced, and we publish where we source it, so the sourcing chain is what backs the unit rather than a claim on our part alone.

31 of 32 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Dioscorea Japonica Root Extract plant extract
- Dioscorea Japonica is Japanese wild yam, whose root is naturally slippery with mucilage. Its extract hydrates and leaves a cushioned feel.
- Viola Mandshurica Flower Extract plant extract
- Viola Mandshurica is Manchurian violet. Its flower extract is used as a conditioning plant extract.
- Aloe Barbadensis Leaf Extract plant extract
- Aloe Leaf Extract is mostly water with polysaccharides, amino acids and mild plant acids. It hydrates and leaves a light, cooling film, which is why it is the default after-sun ingredient.
19 more explained
- Ulmus Davidiana Root Extract plant extract
- Ulmus Davidiana is Japanese elm, whose inner bark yields a naturally slippery mucilage. Korean formulas use the root extract for that cushioned feel and for the look of reactive skin.
- Laminaria Japonica Extract plant extract
- Laminaria Japonica is kombu kelp. Its extract carries alginates, minerals and iodine, and it is used as a hydrating, mineral-rich ingredient.
- Melia Azadirachta Leaf Extract plant extract
- Melia Azadirachta is neem. Its leaf and flower extracts are long-standing Ayurvedic ingredients, and Korean formulas use them in products aimed at the look of congested, blemish-prone skin.
- 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.
- Caprylyl Glycol preservative booster
- Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
- Coccinia Indica Fruit Extract plant extract
- Coccinia Indica is ivy gourd. Its fruit extract is used as a conditioning, hydrating plant extract in Korean formulas.
- Caprylic/Capric Triglyceride emollient
- Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
- Ethylhexyl Palmitate emollient
- Ethylhexyl Palmitate is a palm-derived ester used as a light emollient and a solvent for pigment. It gives a smooth, non-greasy slip.
- Cetyl Ethylhexanoate emollient
- Cetyl Ethylhexanoate is a synthetic ester used as a dry-feeling emollient. It spreads easily, leaves a silky rather than oily finish, and helps disperse pigments and UV filters evenly.
- Solanum Melongena (Eggplant) Fruit Extract plant extract
- Eggplant Fruit Extract carries nasunin, the antioxidant pigment in aubergine skin. It is used as an antioxidant plant extract.
- Ocimum Sanctum Leaf Extract plant extract
- Ocimum Sanctum is holy basil, or tulsi. Its leaf extract carries plant antioxidants and is used in formulas built for the look of stressed, reactive skin.
- Corallina Officinalis Extract plant extract
- Corallina Officinalis is coral seaweed, which holds calcium and magnesium in its structure. Its extract is used as a mineral-rich conditioning ingredient.
- Curcuma Longa (Turmeric) Root Extract plant extract
- Turmeric Root Extract carries curcuminoids, well studied plant antioxidants. It is used for the look of dullness and uneven tone, and it tints a formula faintly yellow.
- Polyglyceryl-10 Myristate emulsifier
- Polyglyceryl-10 Myristate is a mild sugar-derived emulsifier used to keep oil dispersed in a watery formula.
- Hydroxyacetophenone preservative booster
- Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
- 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.
- Carbomer thickener
- Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
- 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.
- 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.
