COSRX 5 PDRN Collagen Intense Vitalizing Serum 100mL

A serum is a leave-on treatment step that adds targeted ingredients after cleansing and toning. Its texture is often lighter than a moisturizer, allowing it to provide conditioning care while leaving room for a final cream. The best placement depends on the product’s directions and the rest of the routine.

This COSRX serum combines PDRN, collagen and humectants for hydration, radiance and a firmer-looking finish. It is designed to absorb with a lightweight feel, making it easy to layer before a moisturizer. The 100mL pump format provides the serum only, separate from the coordinating toner and hydrogel mask.

Five-source PDRN with collagen and lightweight hydration

Explore the formula, texture and packaging details that distinguish this product. These features explain how the ingredients and format fit together, helping you choose the right step for your routine.

• Five-source PDRN blend: COSRX identifies salmon, centella asiatica, rice, lactobacillus and sea grapes behind its PDRN complex. It gives this serum its central conditioning identity within the brand’s PDRN range.
• 200Da collagen: Low-molecular-weight hydrolyzed collagen accompanies the PDRN blend. The formula uses this combination for a supple-looking complexion and a firming-focused step within a regular skincare routine.
• Radiance pairing: Niacinamide and alpha-arbutin are included for the appearance of dullness and uneven tone. They sit alongside moisturizing ingredients rather than replacing the serum’s broader conditioning role.
• Eight hyaluronic acid forms: A range of hyaluronic acid ingredients accompanies glycerin and betaine. This humectant blend supports a hydrated feel while keeping the product in a lightweight serum format.
• Comforting support: Panthenol, allantoin and adenosine round out the formula. These ingredients complement the moisturizing base for skin that feels dry or looks less refreshed and resilient.
• 100mL pump bottle: This is the full 100mL size, not the smaller 50mL bottle. The pump dispenses a leave-on serum intended to be gently massaged into the face until absorbed.

Care that fits your routine

The formula is designed to complement regular care with the following cosmetic benefits. Individual experience can vary with skin or hair condition and the other products in your routine.

• A supple-looking complexion: The PDRN and collagen combination supports the appearance of elasticity. It adds a daily cosmetic conditioning step without implying the same effects as an injectable or in-office treatment.
• More visible radiance: Niacinamide and alpha-arbutin complement the hydrated finish for skin that looks dull or uneven. The serum provides a fresh-looking glow rather than color coverage or shimmer.
• Lightweight moisture: Humectants help replenish moisture while the serum absorbs quickly. This makes it useful when skin needs extra hydration but you prefer not to add a heavy first layer.
• A comfortable skin feel: Panthenol and allantoin accompany the moisturizing ingredients to leave skin feeling conditioned. The formula is intended to support the routine rather than replace a moisturizer when extra protection is needed.
• Straightforward daily layering: Apply at the serum stage and follow with the rest of your skincare. The large pump bottle offers a convenient format for regular face application without a dropper or mixing step.
