ROUND LAB Birch Juice Moisturizing Ampoule 1.69 fl oz — Fast‑Absorbing, 72‑Hour Hydration for Sensitive Skin

ROUND LAB Birch Juice Moisturizing Ampoule is a lightweight, fast-absorbing hydrating ampoule that layers easily and keeps skin comfortably moisturized for up to 72 hours.

Formulated around birch sap and a blend of ten hyaluronic acid molecules plus Aquaxyl, this ampoule focuses on delivering multi-depth hydration without heaviness. The liquid-feeling texture sinks in rapidly—clinically shown to absorb in about seven seconds—and is designed for sensitive skin, having passed dermatological sensitivity testing. Use it alone, as a layering step, or mixed with serums and creams to boost moisture retention over several days.

How quickly will I feel hydration after applying this ampoule?

You should notice the ampoule absorbing almost immediately, with the brand’s testing indicating rapid uptake. The formula targets both surface and deeper layers of the skin so that hydration is felt at multiple levels, not only on the outer layer.

• Clinically measured ~7-second absorption for quick application.
• Contains 10 types of hyaluronic acid to support varying molecular depths.
• Aquaxyl helps reduce water loss and strengthen the skin’s moisture barrier.
• Light, watery texture suitable for layering under other treatments.

Will this ampoule keep my skin hydrated for days?

The formula is designed to lock in moisture and promote longer-lasting hydration; clinical testing reports sustained moisturization up to 72 hours after application when used as directed. That extended effect comes from a combination of multi-weight hyaluronic acids and humectant technology engineered to slow moisture evaporation.

• 72-hour clinical moisture retention in controlled testing.
• Four-layer hydration strategy: surface plus three inner levels.
• Effective as a booster when layered with creams or serums.

Is this ampoule safe for sensitive or reactive skin?

ROUND LAB designed this ampoule to be gentle and non-irritating; it completed sensitivity testing and received certification from a German dermatological assessor. The minimalist, watery formula reduces the chance of pore-clogging or heavy residue, making it suitable for those who prioritize mild, soothing products.

• Passed sensitivity assessments and Derma Test certification.
• Works well under sunscreen and makeup without pilling.

How should I incorporate this ampoule into my routine?

Apply after cleansing and toning while skin is still slightly damp to maximize absorption. Use a few drops across the face and neck, patting gently; follow with serums or creams to seal in moisture. For extra boost, layer multiple thin applications rather than one thick coat.

• Use morning and night after toner or essence for best results.
• Pat 2–4 drops into damp skin; reapply in thin layers for intensive hydration.
• Finish with a moisturizer or sunscreen to lock in benefits.

Who is this for: This ampoule suits people who want lightweight yet substantial hydration—those with dry to combination skin types seeking deeper, multi-level moisture without a heavy feel. It’s also a good option for anyone with sensitive or reactive skin who needs a clinically tested, fast-absorbing product that layers cleanly under other skincare and makeup.
