How to Use Dr. Pen M8S: A Beginner's Guide to Getting Started
Partager
Yes, the Dr. Pen M8S is easy to use — that is one of the main reasons it is recommended for beginners. The basic workflow has four steps: charge the device, snap in a fresh cartridge, dial your depth, and choose a speed. Every control is labeled, the digital display shows your current settings, and the three-snap cartridge lock makes installation straightforward. This guide walks through device preparation, cartridge installation, needle depth adjustment, the basic usage steps, and the aftercare that follows each session.
Before Using Dr. Pen M8S
Device Preparation
Device preparation covers three things: charging, cleaning, and checking the box contents. Charge the M8S with its Type-C cable before your first session — a full charge supports roughly two to three hours of treatment time, and the low-battery reminder (screen icon plus sound alert) tells you when charge is running low. Wipe the device housing with 70% isopropyl alcohol and let it dry completely. Finally, open the two-layer storage case and confirm everything is present: the pen, the Type-C cable, the starter cartridges, and the instruction leaflet.
Cartridge Installation
Cartridge installation on the M8S uses the three-snap locking system. Hold the cartridge against the pen hub, align the three locking points, and press until you hear a click. Gently pull on the cartridge to confirm it is locked in place before turning the device on. A properly seated cartridge should sit flush with the hub, with no wobble. Cartridges come individually sealed and EO-gas sterilized — open a new one only when you are ready to install it, and never install a cartridge that has already been used. Replacement cartridges are available as M8S replacement cartridges in the official store.
Basic Hygiene Considerations
Basic hygiene is the difference between a comfortable session and an avoidable one. Wash your hands thoroughly, clean the treatment area, and keep the device housing sanitized. Use a fresh, sterile cartridge for every session — never reuse a cartridge, because dull or contaminated needles increase the risk of irritation and skin complications (Hartmann et al., 2015). Our home microneedling safety guide covers the complete hygiene checklist.
Understanding Needle Depth Adjustment
Needle depth adjustment is a dial on the cartridge housing that sets how deep the needles penetrate, from 0 to 2.5 mm. The depth setting controls which layer of skin is stimulated, and it is the single most important decision in every session.
| Depth setting | What it means | Typical use |
|---|---|---|
| 0.25 mm | Upper epidermis, very shallow | Under-eyes, product infusion with Nano cartridges |
| 0.5 mm | Epidermis to upper dermis | Full-face sessions, first-time users |
| 0.75–1.0 mm | Mid-dermis | Acne scars, deeper fine lines |
| 1.5 mm and above | Deep dermis | Body areas, stretch marks |
Clinical research confirms that depth directly influences results: a split-face study comparing different microneedling depths found measurable differences in outcome depending on how deep the needles reached (El-Domyati et al., 2024). For a beginner, the rule is simple: start shallow. Set 0.5 mm or less for your first few sessions, observe how your skin responds, and increase depth gradually as your experience grows. Our Dr. Pen needle depth chart shows the safe range for every area of the body.
Basic Steps to Use Dr. Pen M8S
- Prepare the device. Charge the M8S fully and wipe the housing with 70% isopropyl alcohol. Make sure your skin is clean and dry before you begin.
- Install a fresh cartridge. Open a sealed cartridge, align the three-snap lock with the hub, and press until it clicks. Confirm the cartridge is seated firmly.
- Select your settings. Turn the depth dial on the cartridge housing to your chosen depth (start at 0.5 mm or less). Then use the speed buttons to select a low speed level — you can increase speed in later sessions once you are comfortable.
- Follow the device instructions. Switch the pen on, hold it at a comfortable angle, and move it over the skin in small sections using the pattern described in the device instruction leaflet. Do not press hard — the motor does the work — and do not linger in one spot, because repeated passes over the same area over-stimulate the skin. Watch the digital display to confirm your speed setting and battery level, and keep a steady rhythm so the needle contact is even across the treated area. For the complete session workflow, including glide serum and the recommended movement pattern, our step-by-step Dr. Pen tutorial explains every phase in detail.
A typical session lasts 20–30 minutes for a full face. When you finish, switch the device off, remove the cartridge, and dispose of it — cartridges are single-use by design.
Aftercare Considerations
Aftercare after an M8S session is simple but important. Immediately after treatment, rinse the skin with lukewarm water and apply a gentle, hydrating moisturizer — the skin is more receptive right after a session, which is why serum timing matters (Nñanco-Melendez et al., 2024). For the next 24–72 hours, protect the treated area: use sunscreen daily, avoid heavy makeup, intense exercise, saunas, and harsh exfoliating products. Allow the skin to recover between sessions — Nano maintenance every 1–2 weeks, microneedling sessions every 3–4 weeks — so the collagen remodeling cycle, which takes four to six weeks, is not interrupted. Our serum guide explains what to apply at each stage of recovery.
Frequently Asked Questions
Is the Dr. Pen M8S easy to use?
Yes. The M8S is designed for home use: charge via Type-C, install a cartridge with the three-snap lock, dial your depth, and choose a speed. The digital display shows your settings, and the low-battery reminder prevents mid-session interruptions.
How do I install a cartridge on the Dr. Pen M8S?
Align the cartridge with the three locking points on the hub, press until you hear a click, and gently pull to confirm it is locked. Open the sealed cartridge only at the moment of installation.
What depth should I start with as a beginner?
Start at 0.5 mm or less. Observe how your skin responds over the first sessions, then increase depth gradually — the needle depth chart shows safe ranges for every area.
How long does a Dr. Pen M8S session take?
A full-face session takes about 20–30 minutes, including preparation and cartridge installation.
How often can I use the Dr. Pen M8S?
Nano sessions every 1–2 weeks and microneedling sessions every 3–4 weeks. Collagen remodeling takes four to six weeks, so consistency matters more than frequency.
