How it works
Round Lab Birch Juice Moisturizing Cleanser is built as a foam cleanser, so its texture and finish are designed around one specific place in a routine rather than several. The formula's own ingredient list carries Hyaluronic Acid, Sodium Hyaluronate, Birch Sap (Betula Alba Juice) among its named ingredients, placed at a level consistent with a foam cleanser rather than a spot treatment. The texture is built for use first, as your cleansing step, before any leave-on product, which is why it behaves differently on skin than a product meant for a different point in a routine. This is the Korean-market formula of the birch juice moisturizing cleanser, the version sold on shelves in Korea rather than a formula reworked for a different market.
Key benefits
- Four amino-acid-derived surfactants carry the wash: sodium cocoyl alaninate, lauryl hydroxysultaine, disodium cocoamphodiacetate, sodium methyl cocoyl taurate
- Birch sap (Betula Alba Juice) declared at 10,000 ppm, entry eight
- Ascorbic acid and two hyaluronic acid forms sit behind it, unusual for a rinse-off formula
- Chamomile (Anthemis Nobilis) and pine leaf oils are the named scent source, not a generic fragrance entry
- No sulfates (SLS or SLES) on the list
Key actives
Hyaluronic Acid
A water-binding humectant that helps the surface feel plumper and less tight through the day, sitting on skin rather than sinking below it.
Sodium Hyaluronate
A smaller-molecule form of hyaluronic acid that spreads easily and helps the finish feel dewy rather than heavy.
Birch Sap (Betula Alba Juice)
Birch tree sap, carried at a named concentration as the hydrating backbone of this particular Round Lab formula rather than a background botanical.
Ascorbic Acid (Vitamin C)
Direct vitamin C, included in this formula's brightening blend and best paired with sunscreen since it can lose potency with light exposure.
Round Lab Birch Juice Moisturizing Cleanser
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, as your cleansing step, before any leave-on product. 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 foam cleanser is formulated with skin types like normal skin, combination 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.

Payment and security
We accept
How to use
- Use it on damp skin, morning and evening, as the first step of the routine.
- A short pump into wet palms, worked into a soft lather before it goes near the face.
- Massage for twenty or thirty seconds, then rinse with lukewarm water instead of hot.
- In the evening follow an oil or balm cleanse with it rather than using it alone over makeup or sun care.
Worth knowing
- Keep to lukewarm rather than hot water, since hot water is what leaves a cleanser feeling stripping.
- Cut back to once daily if the skin feels tight rather than clean afterward.
