Round Lab Birch Juice Moisturizing Double Gel Mask is a cooling gel mask that intensely hydrates the skin, relieves dryness and flaking, and helps prevent dehydration. It soothes irritation, reduces itching and redness, and promotes the healing of inflammation.
The key active ingredient is birch sap (10,069 ppm) — a rich source of minerals, trace elements, and amino acids. It strengthens the skin’s protective barrier, increases skin density to reduce sensitivity, provides soothing and anti-inflammatory benefits, and accelerates the healing of micro-damage.
The mask is made of a fabric sheet coated with a gel layer, which enhances deep penetration and absorption of active ingredients while helping to lower skin temperature for an instant cooling effect.
Key Active Ingredients:
-
10 types of Hyaluronic Acid with different molecular weights: high-molecular-weight hyaluronic acid restores the protective barrier on the surface, accelerates healing, and reduces flaking, while low-molecular-weight hyaluronic acid penetrates deeply to prevent moisture loss at the cellular level.
-
Glyceryl Glucoside — a derivative of glycerin and glucose that improves the function of aquaporins, proteins that form channels allowing the skin to absorb and retain moisture.
-
Soothing Cooler™ — a patented complex of plant extracts including aloe, kelp (laminaria), dioscorea, David elm, and Manchurian violet. Absorbs excess heat, lowers skin temperature, and helps prevent thermal aging.
-
Hydrokeep-Barrier™ — strengthens and reinforces the lipid barrier, helping to restore the integrity of the epidermis.
-
Tremella (Snow Mushroom) Extract — activates the skin’s protective functions, provides antibacterial benefits, boosts local immunity, and reduces sensitivity to external irritants.
Suitable for: All skin types.
How to Use: After cleansing, toning, and applying serum, place the mask evenly on the face. Remove after 10–20 minutes and allow the remaining essence to absorb into the skin. If needed, finish with a moisturizer.
