ROUND LAB Birch Juice Serum 50ml — lightweight hydrating serum, alcohol- and fragrance-free for sensitive skin

ROUND LAB Birch Juice Serum is a lightweight, 50ml hydrating serum formulated without alcohol, fragrance, or essential oils to boost skin moisture and comfort.

This serum centers on birch sap and Vita Hyaluronic Acid to support immediate hydration and longer-lasting moisture retention. Designed to layer easily under creams or makeup, the formula emphasizes gentle, non-irritating ingredients and is suited to sensitive or moisture-depleted skin types. The product aims to replenish skin feel and improve overall skin texture without added fragrances or alcohol that can dry or sensitize skin.

How does this serum hydrate skin quickly?

The serum uses Vita Hyaluronic Acid to draw and hold water at multiple skin levels, giving an immediate sensation of softness and plumping. Birch sap contributes lightweight, water-like nutrients to help support the skin’s surface moisture balance.

• Vita Hyaluronic Acid for multi-depth hydration
• Birch sap provides a refreshing water base
• Fast-absorbing texture that layers under other products

Will this formula irritate sensitive or reactive skin?

ROUND LAB removes common irritants — alcohol, fragrance, and essential oils — to lower the risk of stinging or redness. The simplified ingredient profile focuses on hydration and skin comfort rather than scent or potent actives.

• No denatured alcohol that can dry skin
• Fragrance- and essential oil-free to minimize irritation
• Gentle texture suitable for layering in sensitive routines

How should I use the Birch Juice Serum in my routine?

Apply the serum after cleansing and any water-based toners, while skin is slightly damp to maximize absorption. Follow with a moisturizer or oil to seal hydration and, in the morning, add SPF to finish your routine.

• Use 2–3 drops for normal application; adjust as needed
• Pat gently until absorbed before adding moisturizer
• Safe to combine with sunscreen and most skincare steps

How does this product support long-term skin moisture?

Beyond immediate hydration, the serum’s humectant-centered approach helps maintain skin moisture between applications. Consistent use can improve the feel of skin surface hydration and reduce the sensation of tightness over time.

• Humectants retain water in the outer skin layers
• Regular use helps sustain a plumper, more comfortable feel
• Complements occlusive moisturizers to lock in benefits

Who is this for: ROUND LAB Birch Juice Serum is aimed at anyone seeking a clean, fragrance-free hydration boost — particularly those with dry, sensitive, or combination skin who want a lightweight serum to add lasting moisture without alcohol or scent. It works well for daily AM and PM routines and for people who prefer simple, non-irritating skincare staples.
