ROUND LAB BIRCH JUICE MOISTURIZING SERUM (50ml)

Round Lab Birch Juice Moisturizing Serum is a lightweight hydrating serum built on birch sap rather than water — the same sap tapped from trees on Korea’s Baekdu mountain range. The 50ml bottle feels closer to a watery essence than a thick serum, which is why it suits people who find most hydrating steps too heavy.

It absorbs in seconds and leaves no tackiness, so it layers well under sunscreen in the morning. Hyaluronic acid handles surface hydration while the birch sap carries minerals that leave skin looking less dull.

Key ingredients:
• Birch Sap — the base of the formula, replacing water entirely
• Hyaluronic Acid — draws and holds moisture in the upper layers

How to use: after toner, apply three or four drops to damp skin and press in. Follow with cream, then sunscreen in the morning.

Suits: all skin types, especially normal to oily skin and anyone who dislikes heavy textures.
