Description
Round Lab’s Birch Juice line is its answer to thirsty, tight skin, and this cream is the line’s best-known moisturizer. It is formulated with sap from silver birch trees grown in Inje, Gangwon Province, listed at 10,000 ppm on the ingredient list. The brand describes birch sap as a natural source of amino acids, minerals and vitamins and pairs it with hyaluronic acid to help skin hold onto moisture throughout the day.
The texture is the big draw: a soft, lightweight cream that spreads easily, absorbs quickly and leaves a smooth, dewy finish rather than a greasy layer. That makes it a practical choice both in the morning under sunscreen and at night.
Key ingredients
- Betula platyphylla japonica (birch) juice – the hero ingredient, sourced from Inje.
- Sodium hyaluronate and hyaluronic acid – humectants that help draw moisture into the skin’s surface.
- Panthenol and glyceryl glucoside – for a comfortable, hydrated feel.
- Glycerin and jojoba esters – adding softness without heaviness.
How to use
- After cleansing, apply your toner.
- Take an appropriate amount of cream and spread it gently over the face.
- Pat lightly to help it absorb. Use morning and evening.
Who it suits
The brand pitches it at dry, tired-looking skin. Thanks to its light texture, it also works well for normal and combination skin, especially in the warmer months. Very dry skin may want to layer it under a richer cream in winter.
Good to know
Size: 80 ml. The brand highlights up to 48 hours of moisture retention in its own testing; individual results vary with climate and routine.
As with any new skincare product, patch-test on a small area (for example behind the ear or along the jaw) for 24–48 hours before using it on the whole face. Stop using it if redness, itching or stinging persists, and avoid applying it to broken or irritated skin. Always check the full ingredient list on the packaging you receive, as formulas can be updated by the brand.
