How it works
A lip balm lives or dies on its oil blend, because there is no water in it to do anything else. This one is built on squalane, jojoba seed oil, macadamia seed oil, sweet almond oil, argan kernel oil and olive fruit oil, with waxes to hold the stick together and tocopheryl acetate behind them. That is a heavier, longer wearing blend than a petrolatum stick, so it stays put through a meal rather than needing a reapply after every drink. It goes on whenever lips feel tight, and last thing at night on lips that wake up cracked. Use it as often as you notice it, and put it on before lipstick rather than over the top of it.
Key benefits
- Squalane plus five plant oils cushion dry lips and smooth the look of lip lines
- Birch sap and betulin, the birch bark compound, tie it to the line's hydrating signature
- Three hyaluronate forms sit in the water phase for added moisture
- Melting balm texture settles into lip lines instead of sitting on top

Round Lab Birch Moisturizing Lip Balm 20g
What does the Birch Moisturizing Lip Balm 20g actually do?
A soft, cushiony lip balm built around Round Lab's birch tree sap, the same base note that runs through the brand's Birch line. It melts on contact and leaves lips comfortably coated rather than glossy or waxy, so it works as well for a bedtime layer as it does for a quick midday touch up. Squalane and Simmondsia Chinensis (Jojoba) Seed Oil are the actives carrying that job on the ingredient list, not a marketing name alone.
Can I use the Birch Moisturizing Lip Balm 20g every day, morning and night?
Smooth over lips whenever they feel dry, and as a final PM step so the balm can work overnight. There is nothing on the ingredient list built to exfoliate or resurface, so daily use in both routines is how Round Lab designed this step to be used, not an occasional treatment.
Can I layer the Birch Moisturizing Lip Balm 20g 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 Lip Balm 20g feel and smell like on skin?
It applies as dense balm that melts on body heat. No added fragrance on the ingredient list. If your skin runs sensitive or reactive, patch test on the inner arm for a day before adding a new step to a full face routine.
Is this the same formula sold in Korea, or a US version made for this market?
The product listed here is the Korean-market release: the same formula Round Lab sells in Korea, with its Korean-market barcode and batch code intact on the box rather than swapped for a US-market SKU. We publish where we source each product, and the packaging itself, read against that sourcing record, is what you are checking when the box arrives.

How to use
- Use the Birch Moisturizing Lip Balm on clean lips, at any point in the day and again as the last thing before bed.
- One pass over each lip is enough, taken just past the lip line rather than well beyond it.
- It goes on last over any lip product, and on bare lips it needs nothing underneath it.
- As often as lips feel dry. Do not reapply over and over in place of drinking water; a balm holds moisture in, it does not add any.
Worth knowing
- Patch test on the inner arm before first use on the face, especially if trying this brand or formula for the first time.
- Store away from direct sunlight and heat so the formula and any actives inside stay stable through its shelf life.
