medicube PDRN Pink Collagen Bubble Serum 3.21 fl.oz — 99% PDRN, Fast-Absorbing Bubble-to-Serum for Dewy Plump Skin

medicube PDRN Pink Collagen Bubble Serum is a lightweight bubble-to-serum formula that transforms on contact to deliver fast-absorbing hydration, visible plumping, and a radiant finish.

This serum pairs a high-purity PDRN concentrate with low-molecular collagen inside a dual-layer, microbubble delivery system designed to sink in quickly without tackiness. It aims to boost surface moisture, support skin elasticity appearance, and create a dewy, healthy-looking glow. The product is free of artificial colorants and fragrances, and its naturally pink tone comes from active components.

How does the bubble texture work and feel on skin?

The formula starts as a soft, aerated mousse that changes to a thin serum when applied, so you get rapid absorption and a smooth finish. The microbubbles break down on contact, releasing the active layers for immediate hydration without heavy residue.

• Bubble-to-serum transformation on application.
• Absorbs quickly—designed to sink in within seconds.
• Leaves skin soft and non-greasy, ideal under makeup.

What are the key ingredients and what do they do?

The product combines 99% purity PDRN with low-molecular collagen in a 90:10 dual-layer arrangement to target surface clarity and suppleness visually. Supporting ingredients such as hyaluronic acid, ceramide, and panthenol focus on hydration and barrier reinforcement for a visibly smoother look.

• 99% PDRN concentrate in the primary layer to enhance radiance appearance.
• Low-molecular collagen in the secondary layer for better dispersion and plumping effect.
• Hyaluronic acid, ceramide, and panthenol to replenish moisture and strengthen the skin’s barrier.

How do I use this serum for best results?

Shake the bottle to blend the dual layers before dispensing a small amount and applying to clean skin after toner. It can be used daily morning and evening, alone or layered under moisturizer or primer; it also works as a serum-soaked mask treatment when applied with cotton pads for targeted radiance.

• Shake well to mix the dual layers, then pump or dispense.
• Apply after cleansing and toning, before heavier creams or sunscreen.
• Use cotton pads soaked with the serum for an intensive short mask.

Will this suit sensitive or combination skin?

The formula is dermatologist-tested for low irritation and formulated without synthetic dyes or added fragrance, making it suitable for many skin types. As with any active product, patch testing is advised for highly reactive skin to confirm tolerance before full-face use.

• Dermatologist-tested and fragrance-free to minimize sensitivity risk.
• Lightweight, non-sticky texture supports combination and oily skin routines.
• Patch test recommended for very reactive skin types.
