1. Cleanse twice — oil-based first, gentle foam second.
2. Inspect the sealed cartridge, click it in until the 3-lock seats, test-fire away from skin.
3. Slip on a protective sleeve — one per session.
4. Set depth 0.25mm, speed level 1–2 for your first session.
5. Apply HA serum to one zone at a time.
6. Glide in overlapping passes — light pressure, 2–3 per zone.
7. Eject the cartridge into a sharps-safe container; sanitize the handpiece.
8. Calm it down: cool serum or the ice roller, nothing else tonight.

Dr. Pen A20 Microneedling Pen
FEATURE OVERVIEW
Every part of the A20 is built to give you a steadier, more predictable session.
Honest answers
The A20 combines the AVOS motor, a 0–2.5 mm depth range, a metal body, and FDA clearance.
Collagen remodeling takes 4–6 weeks. The A20 holds the depth you set, pass after pass.
The Locked-Depth System combines the AVOS vertical stroke, a depth dial that holds its setting, and a three-lock cartridge connection.
Every unit ships sealed with a security label. Scan it and verify your exact pen before you break the seal.
We’re the team behind drpen.net, with 5,900+ verified reviews across our Dr. Pen stores.
Start at 0.25 mm with the depth-by-concern guide in the box. Nothing deeper until you’re ready.

Estheticians already know the difference a stable motor and a secure cartridge lock make over a long day. The A20 gives you consistent, uniform passes, nine depth settings for zone-by-zone control, and a cordless handpiece that keeps your tray clean.
Buy genuine, keep your device documentation, and reorder the same cartridges you trust.
Licensing rules for microneedling vary by state. Check your state board before treating clients.
LOCKED-DEPTH SYSTEM
Microneedling works when needles hit a set depth — and only that depth. The A20 locks it three ways: the AVOS motor drives needles straight in and straight out, the dial holds any depth from 0 to 2.5mm, and the 3-lock cartridge physically can’t wobble loose. That’s the Locked-Depth System.
What to expect
Microneedling is a slow build, not an overnight fix.
Week 1
Skin looks refreshed as it settles. The surface reset, not the real work yet.
Week 4
Texture starts to even out. Most people notice makeup sits better and stops settling into lines by lunchtime.
Week 12
Collagen turnover shows up: smoother tone, softer scar edges, the kind of change people ask about.
Month 6+
With a steady routine, the change holds. Consistency pays off.

FAQ
At 0.25–0.5 mm, most people feel vibration, not pain. Deeper settings are professional territory — that’s what the included Zensa numbing cream in the Pro Kit is for. You control the depth across the full 0–2.5 mm dial.
The A20 holds FDA 510(k) clearance as a Class II medical device for the treatment of facial acne scars in adults 22+. See the clearance details →
The A20 is the flagship: the AVOS motor, a 0–2.5 mm depth dial, a metal body, the 3-lock cartridge system, and FDA clearance. The standard line is a great start — the A20 is the one you don’t upgrade from.
Every A20 ships sealed with a security label. Scan it and verify your exact unit on our Verify page — before you even break the seal. We’re the official US distributor; the documents are public. Verify yours →
Expect redness for 24–48 hours at typical depths — most users do evening sessions and wake up presentable. Deeper professional protocols need longer recovery; the depth guide covers it honestly.
A single clinic microneedling session runs $200–$700 in the US. The A20 with a year of cartridges costs less than two visits. Professionals: two to three client sessions cover the pen.
One cartridge = one session, and a 10-pack is $79 — that’s $7.90 per session. Your free included pack covers roughly the first year at home. Compare that to $300 per clinic visit and the math does the selling. Cartridge pricing →
Then we replace it. 3-year warranty on defects under normal use — email us, we handle it. That’s two years longer than most sellers offer.

Skip microneedling if you’re pregnant, have active acne breakouts, open wounds, or an active skin infection in the treatment area, a history of keloid scarring, or you’ve taken isotretinoin (Accutane) in the last 6 months. Unsure about your situation? Ask your dermatologist first — the pen will wait.
