ROUND LAB Birch Juice Moisturizing Ampoule 1.69 fl oz — Lightweight, Fast-Absorbing Hydration with 10 Hyaluronic Acids

ROUND LAB Birch Juice Moisturizing Ampoule is a lightweight, fast-absorbing hydrating serum that layers quickly to deliver multi-depth moisture without greasiness.

This ampoule is formulated to hydrate skin at multiple layers with a blend of ten hyaluronic acid types plus Aquaxyl and birch juice. Designed for everyday use, it promises quick absorption and a watery texture that fits under makeup and other treatments. Clinical testing highlights its long-lasting hydration and suitability for sensitive skin, so you get a gentle yet high-performance step to add to your routine.

How quickly will I feel hydration after applying this ampoule?

You’ll notice the lightweight formula sinking in almost immediately—ROUND LAB reports a 7-second absorption experience. Within moments the surface feels less tight and more comfortable, while deeper-acting humectants continue to draw and retain moisture over time.

• 7-second rapid absorption for minimal tackiness
• Watery texture designed for quick layering
• Active humectants continue hydrating beneath the surface

What ingredients deliver the four-layer hydration effect?

The ampoule blends ten different molecular weights of hyaluronic acid to target moisture at various depths, while Aquaxyl supports water circulation and birch juice adds lightweight replenishment. Together they work to hydrate the skin surface and the three deeper layers described in clinical testing.

• 10 types of hyaluronic acid for multi-depth moisture
• Aquaxyl to strengthen skin water retention and circulation
• Birch juice for a non-greasy, refreshing base

Is this safe for sensitive skin and everyday use?

Yes — the formula completed sensitivity assessments and holds certification from Derma Test in Germany, indicating good tolerance for vulnerable skin types. Its gentle, watery composition makes it suitable for daily morning and evening routines, including layering with sunscreen and makeup.

• Clinically tested for sensitivity and gentle use
• Lightweight, non-comedogenic feel under makeup
• Appropriate for both AM and PM applications

How long does the moisture last and how should I apply it?

Clinical testing indicates up to 72 hours of skin moisture retention when used as directed, thanks to the combined humectant and barrier-supporting ingredients. Apply a few drops to cleansed skin, pat gently to aid absorption, and layer creams or sunscreen as needed.

• Reported up to 72-hour lasting hydration in clinical settings
• Use 2–4 drops on face; pat for absorption
• Works well under moisturizers, sunscreens, and makeup

Who is this for: ROUND LAB Birch Juice Moisturizing Ampoule is aimed at anyone seeking non-greasy, deeply hydrating skincare—especially people with sensitive or easily dehydrated skin, those who prefer lightweight textures, and anyone who layers products under makeup. It fits routines that require fast absorption and effective moisture maintenance without heavy residue.
