Bonghee had twelve browser tabs open, two different viral Korean bottles sitting in her checkout cart, and a mounting sense of personal crisis. On one side was the Medicube PDRN Pink Peptide Serum, promising elasticity, glow, and salmon DNA technology. On the other was the VT Cosmetics Reedle Shot 100, the prickly micro-spicule booster everyone on beauty forums claimed felt like tiny pinpricks paving the road to glass skin.
“If you buy both of those,” Grandma Malsuk muttered, peering over Bonghee’s shoulder without looking up from slicing scallions, “your face won’t know if it’s getting a spa day or being audited by the department of transportation.”

What Are These Two Products?
At first glance, shoppers frequently lump Medicube PDRN Pink Peptide Serum and VT Reedle Shot 100 into the same “high-tech Korean treatment” category. In reality, they perform fundamentally different jobs in a skincare routine.
- Medicube PDRN Pink Peptide Serum is a concentrated, hydrating treatment serum. Its formulation centers around low-molecular PDRN (Polydeoxyribonucleotide / Sodium DNA) sourced from salmon DNA, paired with a multi-peptide complex, collagen water, and niacinamide. It is designed to sit in the treatment step of your routine to support skin elasticity, surface barrier comfort, and moisture retention.
- VT Cosmetics Reedle Shot 100 is an introductory-strength skin booster designed for use immediately after cleansing. Its primary active delivery mechanism uses microscopic, mineral-derived silica spicules (derived from marine sponges and coated with Centella Asiatica). These micro-needles physically stimulate the stratum corneum to refine uneven texture and create micro-channels that allow subsequent skincare steps to absorb more efficiently.
Why People Are Talking About Them
Both products exploded across social media and Olive Young rankings, but for very different reasons.
Medicube caught global attention by bringing injectable-inspired PDRN—traditionally famous in Korean aesthetic clinics for skin rejuvenation—into an over-the-counter daily pink serum.
Meanwhile, VT Cosmetics sparked intense consumer fascination with the Reedle Shot’s physical sensation. It mimics in-clinic microneedling at home through natural marine spicules, producing an undeniable prickling feeling that makes users immediately feel the product working.
Ingredient & Formula Breakdown
Understanding how these two work on paper removes the confusion about which one you actually need.
Medicube PDRN Pink Peptide Serum├── Sodium DNA (PDRN) ── Skin condition & elasticity support├── Multi-Peptide Complex ── Structural firmness signals└── Niacinamide + Cyanocobalamin (B12) ── Radiance & pink hueVT Cosmetics Reedle Shot 100├── Cica Reedle™ (Silica Spicules) ── Micro-channel opening & texture refinement├── Centella Asiatica Extract ── Soothing & anti-redness support└── Low-Molecular Hyaluronic Acid ── Immediate surface hydration
Medicube PDRN Pink Peptide Serum
- Sodium DNA (PDRN): Clinically studied in dermatology for tissue repair, topical cosmetic PDRN functions as an advanced conditioning agent that helps nourish skin vitality and support elasticity. It cannot duplicate clinical injections, but it acts as a rich regenerative ingredient.
- Peptide Complex & Collagen Extracts: Supply amino acid building blocks to help smooth fine surface dehydration lines and improve firmness over consistent application.
- Cyanocobalamin (Vitamin B12): Gives the serum its signature natural pink tint while assisting barrier comfort and antioxidant protection.
VT Cosmetics Reedle Shot 100
- Hydrolyzed Sponge Spicules (Cica Reedle™): Microscopic needle-like structures that gently prick the skin’s surface during application. This mild mechanical stimulation prompts surface cell turnover and helps subsequent serums absorb more effectively.
- Centella Asiatica Complex: Soothes surface irritation, mitigating potential redness caused by the physical action of the spicules.
- Low-Molecular Hyaluronic Acid: Delivers immediate moisture alongside the penetration booster.
What This Means for Your Skin
These formulas represent two distinct steps in a regimen:
- VT Reedle Shot 100 acts as the “door opener.” It does not supply heavy anti-aging actives on its own; its primary job is smoothing surface roughness and helping your active serums penetrate past stubborn dead surface buildup.
- Medicube PDRN Serum is the “nourishing active.” It delivers peptides and moisture-binding compounds directly to dry, tired, or thinning skin.
If your skincare feels like it just sits on top of your face like grease on plastic, the issue is often surface buildup and absorption, which aligns with the VT Reedle Shot mechanism. If your skin absorbs products fine but feels depleted, crepey, or lacking bounce, you need the reparative moisture profile of the Medicube PDRN Serum.
Texture & Finish
- Medicube PDRN Pink Peptide Serum: Fluid yet slightly cushiony. It glides across the skin with a soft slip, imparting an immediate dewy finish that dry to normal skin types will appreciate. It leaves a light, protective emollient shield without excessive stickiness when applied sparingly.
- VT Reedle Shot 100: A watery, fast-absorbing lotion-gel. Upon application, it produces a distinct tingling, prickling sensation that persists for several minutes or when touching the face afterward. It finishes semi-matte with virtually no residue, allowing immediate application of a hydrating essence or serum over it.
Who Is It Best For?
Choose Medicube PDRN Pink Peptide Serum if:
- Your skin feels chronically dehydrated, lackluster, or depleted.
- You want a gentle, non-irritating anti-aging serum focused on bounce and glow.
- You are sensitive to physical exfoliants or aggressive skin stimulators.
Choose VT Reedle Shot 100 if:
- You struggle with stubborn, rough skin texture and uneven tone.
- You feel your existing active serums have plateaued and aren’t absorbing well.
- Your skin is resilient enough to handle mild tingling and physical micro-stimulation.
Who Should Skip It?
- Skip Medicube PDRN if you have very congestion-prone, oily skin that breaks out easily from rich conditioning agents, or if you are seeking physical texture smoothing.
- Skip VT Reedle Shot 100 if you have active inflammatory cystic acne, rosacea flare-ups, open skin lesions, or an acutely damaged skin barrier. Never apply micro-spicules to irritated or wounded skin.

How to Use Them in a Routine
Because these two products serve different operational purposes, they do not have to be an either/or purchase—though beginners should never start both on the same night.
VT Reedle Shot 100 (Evening First Step) ↓Wait 1–2 minutes (Let skin settle) ↓Medicube PDRN Pink Peptide Serum (Treatment Step) ↓Barrier Moisturizer (Lock in hydration)
- Cleansing: Wash face thoroughly and pat dry.
- Booster Step (VT Reedle Shot 100): Dispense 1–2 pumps onto clean, dry skin. Press and lightly roll into the skin—do not vigorously rub. Expect a distinct prickle.
- Treatment Step (Medicube PDRN Serum): Smooth 2–3 drops across the face. The micro-channels from the Reedle Shot allow the peptides and low-molecular PDRN to sit smoothly over freshly primed skin.
- Moisturizer: Seal everything with a soothing, ceramide-rich cream.
Caution: If you are testing VT Reedle Shot 100 for the first time, pair it only with basic hydrating formulas first. Avoid layering it with high-strength exfoliating acids (AHA/BHA) or concentrated pure ascorbic acid until you know your tolerance.

Bonghee’s Take
Here’s where people go wrong: they see two viral Korean bottles on their feed and assume they are competing for the exact same shelf space.
If my skin feels parched, flat, and desperate for bounce, Medicube PDRN is the obvious pick—it feels plush and gives an instant plumping glow without fuss. But if my skin feels like sandpaper and nothing I apply seems to penetrate, the VT Reedle Shot 100 is the tool that actually wakes up the surface. You don’t need both on day one, but knowing which problem you’re trying to solve saves you thirty dollars and a lot of product confusion.

Malsuk Halmae’s Verdict on choosing between Medicube PDRN and VT Reedle Shot 100
Final Verdict
Choose the Medicube PDRN Pink Peptide Serum if your primary goal is barrier comfort, elasticity support, and restoring a healthy, supple sheen to dull or mature skin. It works quietly and gently as an everyday hydrating treatment.
Choose the VT Cosmetics Reedle Shot 100 if your primary frustration is sluggish skincare absorption and gritty surface texture. It functions as a targeted tool to prep your skin for other treatments—provided your barrier is healthy enough to handle the micro-tingle.
Frequently Asked Questions
Can I use VT Reedle Shot 100 and Medicube PDRN Serum together?
Yes. In fact, many K-beauty routines intentionally pair them because VT Reedle Shot acts as a penetration enhancer, helping the peptides and low-molecular PDRN in the Medicube serum absorb more effectively. Always introduce one product at a time to monitor your skin’s tolerance.
Does the VT Reedle Shot 100 prickling sensation mean my skin is burning?
No. The tingling feeling comes from microscopic silica spicules gently engaging the upper stratum corneum to create micro-channels. It should feel like mild prickles, not chemical burning or allergic stinging. If redness, intense heat, or swelling occurs, rinse thoroughly.
Does topical Medicube PDRN give the same results as Korean clinic injections?
No. In-clinic Korean Rejuran injections deliver pharmaceutical-grade polynucleotides directly into the dermis. A topical serum like Medicube supports surface hydration, elasticity, and radiance, but no topical cosmetic product can replicate medical injection depth or results.
Can I use VT Reedle Shot 100 every night?
The Reedle Shot 100 is formulated as an introductory, daily-use concentration for resilient skin. However, beginners should start by using it 2 to 3 times a week at night, gradually increasing frequency as their skin adapts to the spicule stimulation.
Will Medicube PDRN Serum cause breakouts on acne-prone skin?
The serum contains emollient conditioning agents to support barrier repair and elasticity. While it is generally well tolerated, those prone to fungal acne or pore congestion from rich oils should patch test before applying it all over the face.
