Dr. Pen Hydra Needle HN20: The All-in-One Serum Infusion Derma Stamp

What Is the Hydra Needle HN20?

The Dr. Pen Hydra Needle HN20 is not your typical derma stamp. It's an all-in-one microneedling device that combines a 20-pin gold-plated needle head with a built-in 5ml glass serum vial — allowing you to infuse serums directly into the skin during treatment for dramatically enhanced absorption.

How Is It Different from a Regular Derma Roller?

Traditional derma rollers create micro-channels in the skin, but the serum is applied separately. The HN20 takes it a step further: the serum is loaded into the attached vial and delivered directly through the needle channels as you stamp — maximizing absorption by up to 80% compared to topical application alone.

Key Features

• 20-Pin 24K Gold-Plated Medical Steel Needles: Gold plating reduces friction and skin irritation for a smoother, more comfortable treatment.
• Built-in 5ml Glass Serum Vial: Load your favorite serum — hyaluronic acid, vitamin C, peptides — and infuse it directly into the skin.
• Available Needle Sizes: 0.25mm, 0.5mm, 1.0mm, 1.5mm — choose based on your skin concern and sensitivity.
• Non-Screw Hygienic Joints: Anti-bacterial design prevents contamination between uses.
• Improved Curved Edge: Ergonomic design for comfortable, effective stamping on facial contours.
• Blister Packaging: Each unit is hygienically sealed for safe, sterile use.

Best Serums to Use with the HN20

• Hyaluronic Acid: Deep hydration and plumping
• Vitamin C: Brightening and pigmentation reduction
• Peptide Serums: Collagen stimulation and anti-aging
• Growth Factor Serums: Skin repair and regeneration

How to Use the Hydra Needle HN20

1. Cleanse and dry your skin thoroughly.
2. Fill the glass vial with your chosen serum (do not overfill).
3. Stamp gently across the treatment area — 4–5 passes horizontally, vertically, and diagonally.
4. Maintain consistent pressure and speed for even results.
5. After treatment, apply a soothing moisturizer or additional serum.
6. Sterilize the needle head with 70% isopropyl alcohol before and after each use.

Who Is the HN20 For?

The HN20 is ideal for anyone who wants to supercharge their serum routine, target fine lines and dull skin, improve skin hydration and glow, and achieve professional-level results at home.

Final Verdict

The Dr. Pen Hydra Needle HN20 is a game-changer for serum lovers. By combining microneedling with direct serum infusion, it delivers results that topical application simply can't match. If you're serious about your skincare, the HN20 belongs in your routine.
