ROUND LAB 라운드랩 · Birch Juice Moisturizing Cream 자작나무 수분 크림 · 80 ml · US Formula
Moisture that weighs nothing.The cream for people who usually skip cream.
Round Lab Birch Juice Moisturizing Cream folds 1% Inje birch sap, two forms of hyaluronic acid, panthenol and a touch of vitamin C into a bouncy gel-cream that melts in fast and leaves no greasy film. Round Lab reports 48-hour moisture, Ulta shoppers rate it 4.8 stars, and it was on the launch shelf at Olive Young's first US store — and 100% authentic at MIMOMART.
Hydration without the heaviness. A water-light gel-cream with glycerin, two hyaluronic acids and birch sap that sinks in fast — built for oily, combination and dehydrated skin.
Plays well with SPF and makeup. No silicones, no plant butters, no fragrance — just a smooth, quick-setting base that pairs naturally with Round Lab Birch Juice UVLOCK Sun.
Shoppers back it up. 4.8 stars across 163 Ulta reviews, with 100% of respondents saying they'd recommend it.

Know Before You Buy
What Round Lab Birch Juice Moisturizing Cream reviews reveal that the label won't tell you
What we found in 163 Ulta reviews and the fine print
It's a gel-cream that holds its shape. One reviewer compares it to aloe, but thick enough to sit on a fingertip. It melts in fast and layers under sunscreen without pilling.
Dry skin: a summer cream. A dry-skin reviewer who loves it in warm months calls it too light for winter. When the heat comes on, switch to the richer Round Lab 1025 Dokdo Cream or layer it over a hydrating toner.
Fragrance-free isn't scentless. No fragrance is added, but reviewers notice a faint natural scent. Round Lab notes color and scent can shift a little over time because of the plant ingredients.
Birch allergy? Skip it. Birch sap is the base. The only 1-star review on Ulta warns people with tree allergies. If birch pollen sets you off, patch test or choose another cream.
Use the spatula. The jar comes with one. It keeps fingers out of the cream and the jar clean to the last scoop.
No SPF. It's a moisturizer only. Follow it with sunscreen in the morning.
Why It Went Viral
How Round Lab Birch Cream went from Korean favorite to US shelf regular
Round Lab built its name on one idea: take a single ingredient from a specific corner of Korea and build a whole line around it. The 1025 Dokdo line draws on deep sea water from the East Sea. The Birch line taps sap from the birch forests of Inje, in Gangwon Province. Korean-language listings tag the Birch Juice Moisturizing Cream #수부지, slang for skin that's oily on the surface but dehydrated underneath. That's exactly the problem this gel-cream is built to solve.
Then the line crossed the Pacific. Round Lab Birch Juice Moisturizing Cream is now stocked at Ulta Beauty, where it holds a 4.8-star average. When Olive Young opened its first US store in Pasadena in June 2026, Round Lab was part of the launch lineup, with the Birch Juice Moisturizing Cream on shelf next to the brand's best-selling Birch UV Lock sunscreen. Reviewers keep coming back to the texture: light enough for humid days, with enough moisture that skin doesn't feel tight by noon.
One Jar, Two Routines
Round Lab Birch Juice Moisturizing Cream, morning and night: thin by day, generous by night
Mode 1 · Morning base
Thin layer + Birch UVLOCK Sun
A pea-sized amount spreads across the whole face and sets in about a minute, leaving a soft, non-tacky finish that sunscreen and makeup glide over. For the full birch routine, follow with Round Lab Birch Juice Moisturizing UVLOCK Sun SPF 45 as your AM partner.
AM · every day
Mode 2 · Night seal
Generous layer + nothing else
At night, use it as the last step of your routine. Round Lab suggests spreading a generous amount “as if creating a barrier” so skin feels cushioned and comfortable until morning. You still get no greasy pillowcase.
PM · last step
The Formula Philosophy
Why a gel-cream beats a heavy cream for oily, dehydrated skin
Water first, oil-light. Oily skin can still be dehydrated, meaning short on water rather than oil. Glycerin, glyceryl glucoside and two sizes of hyaluronic acid pull water into the skin's surface.
Featherweight emollients instead of butters. Isononyl isononanoate, isododecane and polydecene give slip and softness, then evaporate or set quickly. You get no shea, no petrolatum and no silicones.
A light seal, not a lid. Jojoba esters and panthenol help skin hold onto moisture, so it feels comfortable for hours without the slick film rich creams can leave.
The “capsule” texture. Agar and acacia gum give the cream its bouncy, water-burst feel. Round Lab calls these moisture capsules that melt as you spread.
Inside the Jar
Round Lab Birch Juice Moisturizing Cream ingredients, decoded
Inje birch sapBetula Platyphylla Japonica Juice
Hero botanical
The sap of Korean white birch, tapped in spring. It's naturally watery and mineral-rich, and it gives the line its fresh, hydrating identity. Round Lab lists it at 10,000 ppm (1%).
Glycerin is the workhorse humectant, and it's the second ingredient here. Glyceryl glucoside, a glycerin-sugar pairing, adds a smooth, plump-feeling layer of hydration.
Two hyaluronic acidsSodium Hyaluronate, Hyaluronic Acid
Hydration
Two forms of hyaluronic acid that hold water at the surface for a dewy, bouncy feel. They make up half of what Round Lab markets as “Vita Hyaluronic Acid.”
Vitamin CAscorbic Acid
Antioxidant
The other half of “Vita Hyaluronic Acid.” It's an antioxidant that helps skin look fresh, but it sits near the end of the list, so think of it as a supporting player rather than a vitamin C serum.
Panthenol + jojoba estersPanthenol, Jojoba Esters
Comfort
Panthenol (pro-vitamin B5) keeps skin feeling soft and calm. Jojoba esters are a wax-like conditioner that helps lock moisture in without an oily finish. Round Lab names both as key ingredients next to birch sap.
Licorice-root derivativeDipotassium Glycyrrhizate
Soothing feel
A licorice-derived ingredient that's common in Korean formulas for skin that looks flushed or feels stressed.
A small-dose mix of plant and algae extracts that adds antioxidant support. These are present in tiny amounts. They're not why the cream works, but they round out the formula.
These give the cream its silky glide. Isododecane is volatile, so it evaporates after application. That's why the finish feels light, not slick.
Editor's note on “Birch Juice”: The name might suggest a sap base, but water is the first ingredient. Birch sap is listed eighth and stated by Round Lab at 1%. The hydration you feel mostly comes from glycerin, glyceryl glucoside and hyaluronic acid. Birch sap is the line's signature botanical, not the bulk of the formula. Also note that different US retailer listings print the same ingredients in a different order. The full list below follows the Ulta Beauty listing.

Who It's For
Who Round Lab Birch Juice Moisturizing Cream is for: made for you if your skin is…
Oily or combination, but still feels tight
Dehydrated: dull, crepey-looking, thirsty
Easily overwhelmed by heavy creams
Prone to looking shiny by midday
Living somewhere humid, or it's summer
Wearing sunscreen or makeup over moisturizer
Sensitive to fragrance
Keeping a short, simple routine
Patch test first if: you have a birch or tree-pollen allergy (one Ulta reviewer flagged a reaction and suggested pollen-allergic shoppers avoid the line), or you're sensitive to botanical extracts such as turmeric, neem, aloe or licorice. Apply a small amount on the jawline or inner arm for a few days before using it on your full face.
What People Actually Use It For
Round Lab Birch Cream hacks that made it a cult favorite
01
The no-pilling SPF base
A thin layer, a minute to set, then Birch Juice UVLOCK Sun. Both come from the same birch line, so they're made to layer smoothly.
02
The summer night cream
Swap a heavy night cream for this on hot, sticky nights. You get enough moisture to wake up comfortable without the slick.
03
The sheet-mask seal
After a sheet mask, pat in the leftover essence, then a thin layer of the cream to hold that hydration in place.
04
The post-shave moisturizer
Fragrance-free and fast-absorbing, so it's comfortable on freshly shaved cheeks and neck when an aftershave feels too sharp.
What Reviewers Keep Saying
Round Lab Birch Juice Moisturizing Cream reviews: the pulse
Top praise
Light, bouncy and gone in seconds
The texture wins people over. Skinsort users most often tag it hydrating, light and absorbs well, and Ulta reviewers compare it to a gel that melts on contact.
Surprise favorite
Hydrating enough, even for oily skin
Reviewers with oily and combination skin say it keeps skin comfortable without shine, and several say it didn't clog their pores.
Honest critique
Not rich enough for very dry skin
In cold, dry weather or on very dry skin it can feel too light alone. Layer a hydrating toner underneath, or switch to the creamier 1025 Dokdo Cream. A small number of reviewers report reactions, so patch test.

How to Use
How to use Round Lab Birch Juice Moisturizing Cream for all-day bounce
1
Cleanse and toneStart with a gentle cleanser, then pat in a hydrating toner while skin is still slightly damp.
2
Serum, if you use oneApply any serum or essence first. The cream goes on after, as the last skincare step.
3
Spread, don't rubTake a pea-sized amount (more at night) and spread it evenly over the whole face. Round Lab suggests spreading it “as if creating a barrier.”
Extra-thirsty daysApply a thin layer, wait 30 seconds, then add a second thin layer. Two light passes hydrate better than one thick one, and the cream still won't feel heavy.
Pro tips from people who use it daily
Less is more. The gel spreads far, so start small. Reviewers say a little goes a long way.
Damp skin helps. The humectants work best with some water to hold onto, so apply soon after toner.
Pair it within the line. Birch cream plus Birch UVLOCK Sun is a light, two-step morning routine.
FAQ
Round Lab Birch Juice Moisturizing Cream: your questions, answered
Round Lab Birch Juice Moisturizing Cream vs. 1025 Dokdo Cream: which one should I buy?
Choose by skin type. Birch Juice Moisturizing Cream is a light, silicone-free gel-cream built on humectants: hyaluronic acid, glycerin and 1% birch sap. It's the better match for oily, combination and dehydrated skin, humid climates, and wearing under sunscreen. The 1025 Dokdo Cream is creamier, with five ceramides, cholesterol, shea butter and deep sea water, so it's the better match for normal to dry skin that wants more cushion. Some people keep both: Birch for summer, Dokdo for winter.
Is Round Lab Birch Juice Moisturizing Cream good for oily skin?
Yes. That's who it was designed for. It has no plant butters or silicones, and its emollients are light and quick-setting. Round Lab reports the cream is non-comedogenic tested and lowered skin-surface oil in its clinical testing.
Is Round Lab Birch Cream enough for dry skin?
For mildly dry or dehydrated skin, often yes, especially layered over a hydrating toner. For very dry skin or cold weather, it can feel too light alone. Layer two thin coats, or choose the richer 1025 Dokdo Cream. Browse more options in our dryness and dehydration collection.
Can I use Round Lab Birch Juice Moisturizing Cream with the Birch Juice UVLOCK Sun?
Yes. They're designed as a pair. Apply the cream as your last skincare step, let it set for about a minute, then apply Round Lab Birch Juice Moisturizing UVLOCK Sun SPF 45 as your final morning step. Reapply sunscreen as directed on its label.
Is Round Lab Birch Juice Moisturizing Cream fungal acne safe?
Not by the strictest standard. Skinsort flags two ingredients, jojoba esters and polyglyceryl-3 methylglucose distearate, as potential triggers for people who follow fungal-acne-safe ingredient lists. If you avoid those ingredients, check the full list below before buying.
How much birch juice is in Round Lab Birch Juice Moisturizing Cream?
Round Lab lists Inje birch sap at 10,000 ppm, which is 1%. Water is the base, and most of the hydration comes from glycerin, glyceryl glucoside and hyaluronic acid. See the editor's note above.
Is Round Lab Birch Moisturizing Cream the same as Birch Juice Moisturizing Cream?
Yes. Round Lab's US website lists it as “Birch Moisturizing Cream,” while Ulta Beauty and most retailers call it “Birch Juice Moisturizing Cream.” It's the same 80 ml cream.
Is Round Lab Birch Juice Moisturizing Cream fragrance-free?
Yes. Round Lab and Ulta both list it as fragrance-free. It contains a small amount of turmeric root extract, which some databases tag as a fragrance-capable botanical, but no fragrance is added.
What is Round Lab Birch Juice Moisturizing Cream called in Korean?
In Korea it's sold as 라운드랩 자작나무 수분 크림, which translates to “Round Lab birch moisture cream.” 자작나무 means birch tree.
