Round Lab Birch Juice Moisturizing Face Serum – 50 ml

A lightweight serum for the daily care of dry, dehydrated, sensitive skin in need of soothing. The formula with birch juice, a complex of three forms of hyaluronic acid, beta-glucan, and plant extracts intensely hydrates, smooths, and helps restore the skin’s comfort. Its watery, gently gel-like texture absorbs quickly without leaving a greasy or heavy layer.

Benefits and effects

The serum helps maintain the skin’s proper moisture level and reduces unpleasant feelings of dryness and tightness. Birch juice softens and refreshes the complexion, while hyaluronic acid helps bind water in the epidermis. Beta-glucan, aloe flower extract, and oat extract soothe irritation and support the skin’s natural protection against free radicals. With regular use, the complexion is left softer, smoother, and more radiant.

After cleansing and toning, apply an appropriate amount of serum to the face, neck, and décolleté. Gently pat the product in until fully absorbed, then apply a moisturizer.

1. Thoroughly cleanse your face and apply toner
2. Apply a small amount of serum to your face, neck, and décolletage
3. Gently massage or pat the product in until absorbed
4. Finish your skincare routine with your favorite moisturizer, and apply SPF protection in the morning

Intense hydration with birch sap


The formula contains birch sap, which helps maintain an appropriate level of hydration, softens the skin, and helps reduce feelings of dryness. The serum is especially suitable when the complexion looks tired, dull, or dehydrated.

Three forms of hyaluronic acid


The combination of Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, and Hyaluronic Acid helps provide hydration to the skin at different levels. These ingredients bind water in the epidermis, support a smoother skin surface, and give it a more supple, fresh appearance.

Soothing care without weighing hair down


Beta-glucan, aloe flower extract, oat extract, and other plant extracts help soothe irritation and improve skin comfort. The lightweight texture works well with subsequent skincare steps and makeup, leaving no sticky or greasy residue.
