Dr. Pen Hydra Needle HN20 Serum Infusion Derma Stamp

About HN20 

The HN20 is built around a 24K gold-plated medical steel needle head — 20 pins, four adjustable depth settings, and a curved-edge stamp design that maintains even contact across facial contours. The integrated 5ml glass vial holds serums securely without leaching, and the non-screw-joint mechanism eliminates a common contamination point in competing devices.

Blister packaging ensures each unit reaches your client in sterile condition — no compromises on hygiene at the point of unboxing.

Available needle depths:

• 0.25mm — Gentle exfoliation, serum priming, surface glow
• 0.50mm — Fine lines, mild pigmentation, texture refinement
• 1.0mm — Acne scarring, enlarged pores, deeper tone correction
• 1.5mm — Collagen induction, skin laxity, advanced resurfacing

What It Treats

The HN20 covers the skin concerns most clients walk in asking about — dullness, uneven texture, fine lines, enlarged pores, and dehydration. Regular use improves exfoliation, enhances serum absorption, smooths skin surface, and builds a lasting luminous tone over time.

How to Use — Treatment Protocol

1. Disinfect the stamp fully before every session — sterility first, always
2. Cleanse skin and remove all traces of makeup before beginning
3. Fill the 5ml glass vial with your serum of choice — hyaluronic acid is recommended for hydration, though any targeted serum applies
4. Stamp the treatment area in horizontal, vertical, and diagonal passes — 4 to 5 passes per direction
5. Keep speed and pressure consistent throughout for even serum distribution
