medicube PDRN Pink Collagen Bubble Serum — Dual-Layer Firming Hydration, Lightweight Non-Sticky Finish

medicube PDRN Pink Collagen Bubble Serum is a dual-layer bubble-to-glow serum that combines 99% purity PDRN with collagen to hydrate, plump, and visibly firm skin while delivering a lightweight, non-sticky finish.

This innovative serum pairs a high-purity PDRN-rich phase with a collagen-rich layer in a 90:10 golden dual-layer formula to protect and nourish skin. The product is designed to activate into a soft, bouncy bubble texture on application, delivering concentrated ingredients like hyaluronic acid, ceramide, and panthenol without heavy residue. Dermatologist-tested and free from artificial colorants and fragrances, the naturally pink tint comes from the active blend rather than dyes.

How does the bubble-to-glow texture work on my skin?

When dispensed, the serum presents two distinct layers that blend into a light, foamy texture while massaging into the skin. The bubbles create a cushiony feel that improves spreadability and helps active ingredients absorb evenly across the face. Despite the airy texture, the formula sinks in and leaves a smooth surface ideal for layering under moisturizer and sunscreen.

• Dual-layer formula creates an effervescent application experience
• Soft bubble texture increases spreadability and absorption
• Leaves no greasy film—ready for follow-up skincare steps

What key ingredients are inside and what do they do?

The serum highlights 99% purity PDRN and collagen in a 90:10 ratio, supported by moisture-binding hyaluronic acid, barrier-reinforcing ceramide, and soothing panthenol. PDRN is included to promote skin clarity and vitality, while collagen contributes to a smoother, more supple-looking finish. Hyaluronic acid and ceramide work together to replenish and lock in moisture for lasting comfort.

• PDRN (high purity) for visible clarity and rejuvenated appearance
• Collagen to support skin’s supple texture and bounce
• Hyaluronic acid and ceramide for deep hydration and barrier support
• Panthenol for soothing and reduced tightness after application

Is this serum suitable for sensitive or combination skin?

Yes — medicube formulated this serum to be gentle: dermatologist-tested with a low irritation profile and free from added fragrances or artificial colors. The lightweight, non-greasy finish is especially suitable for combination and oilier skin types, while the hydrating actives support drier areas too. As always, patch testing is recommended if you have very reactive skin.

• Dermatologist-tested for low irritation potential
• Fragrance- and artificial colorant-free, naturally pink
• Lightweight texture suits combination to oily skin types
• Hydration blend supports normal to dry areas seamlessly

How should I add this serum into my routine?

Use the serum after cleansing and toning, once or twice daily, depending on your routine and skin needs. Gently massage a pea-sized amount across the face until bubbles form and dissolve, then follow with moisturizer and sunscreen in the daytime. Because it layers cleanly, it works well under heavier creams or makeup prep steps.

• Apply after cleansing and any water-based toners or essences
• Massage until bubbles settle and serum absorbs
• Finish with moisturizer; use sunscreen during the day
• Suitable for AM or PM, based on moisture needs
