Bubble-to-Glow in 10 Seconds: The Viral K-Beauty Serum That's Rewriting Hydration

The Medicube PDRN Pink Collagen Bubble Serum is unlike anything else in your skincare routine. The moment it touches your skin, ultra-fine microbubbles burst on contact and absorb completely within 10 seconds — delivering a precise, concentrated hit of 99% purity PDRN, 5% Niacinamide, and low-molecular collagen deep into the skin with zero stickiness and zero residue.

The formula uses a patented dual-layer 90:10 design — a PDRN-dominant layer and a collagen-rich layer — kept separated in the bottle to preserve potency and freshness, then activated the moment you shake and dispense. This isn't just a serum. It's a delivery system.

The Ingredient Stack — What's Actually In It

• 99% Purity PDRN (Polydeoxyribonucleotide) PDRN is the most talked-about active ingredient in K-beauty right now — originally used in clinical dermatology and skin regeneration treatments. At 99% purity, Medicube's PDRN works to improve skin clarity, vitality, and the appearance of overall skin quality at a level most serums can't touch.
• 5% Niacinamide The #2 ingredient in this formula by concentration. At 5%, Niacinamide visibly evens skin tone, reduces the appearance of pores, controls excess sebum, and reinforces the skin barrier — all while enhancing the glow effect of the PDRN and collagen.

• Low-Molecular Collagen (Triple Complex: Collagen + Collagen Extract + Hydrolyzed Collagen) Three forms of collagen work together to support a supple, smooth, plumper-looking complexion. Low-molecular weight means better skin penetration than standard collagen.

• 6-Form Hyaluronic Acid Complex Sodium Hyaluronate, Hyaluronic Acid, Hydrolyzed Hyaluronic Acid, Hydrolyzed Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer, and Sodium Acetylated Hyaluronate — six distinct molecular weights of HA targeting hydration at every layer of the skin simultaneously. This is the engine behind that +261% hydration figure.

• Ceramide NP + Panthenol Barrier-sealing ceramides and soothing pro-vitamin B5 prevent moisture loss and keep skin calm throughout the day — especially important for those using PDRN alongside retinol or acids.

• Retinol Yes — this serum also contains Retinol, making it one of the most multi-functional K-beauty serums on the market. Use PM if you're retinol-sensitive or new to actives, and always follow with SPF in the morning.
• Adenosine + Tocopherol (Vitamin E) Anti-aging and antioxidant support for fine lines and environmental damage protection.
• Cyanocobalamin (Vitamin B12) Responsible for the serum's signature pink color — no artificial dyes. The pink hue is entirely natural, derived from the concentrated active ingredients themselves.

Who This Serum Is For:

• Anyone wanting visibly brighter, more radiant skin fast
• Those dealing with dullness, uneven tone, or lackluster complexion
• Skin that feels dehydrated or flat despite layering moisturizers
• Anyone interested in PDRN skincare without a clinical price tag
• Retinol users who want a multi-tasking, glow-first formula
• People who need their skincare done in under 60 seconds
