Using a Dr. Pen for the first time can feel complicated, especially with different cartridges, speed levels, and adjustable needle settings to consider.
This beginner’s guide covers the basics of using a Dr. Pen for cosmetic microneedling, including preparation, cartridge setup, device controls, general technique, hygiene, and aftercare.
Because Dr. Pen models vary in design and specifications, always follow the instructions supplied with your specific device.
Dr. Pen is an electric microneedling device that uses a motorized cartridge with vertical needle movement.
Unlike a traditional derma roller, which is manually rolled across the skin, Dr. Pen devices use replaceable cartridges and adjustable controls.
Depending on the model, features may include:
Specifications vary between models, so speed levels, depth ranges, cartridge systems, and controls should always be checked for your specific device.
Good preparation and hygiene are important parts of a cosmetic microneedling routine.
Before using your Dr. Pen:
Never use a cartridge if its sterile packaging is already open or damaged.
Dr. Pen devices support different cartridge configurations depending on the model.
Available options may include:
Not every cartridge fits every Dr. Pen.
Different generations may use different cartridge shapes, locking mechanisms, or connection systems. Even cartridges with the same pin count should not automatically be assumed to be interchangeable.
Before purchasing or opening a cartridge, confirm compatibility with your exact Dr. Pen model.
Traditional needle cartridges contain individual microneedles and are designed for cosmetic microneedling.
Nano cartridges use a different tip configuration and are intended primarily for more superficial cosmetic skincare applications.
Available Nano designs vary by device, so choose a cartridge specifically designed for your Dr. Pen model.
Installation varies between models. Your device manual should always be your primary reference.
Make sure your Dr. Pen is clean, sufficiently charged, and ready for use.
Open a new sterile cartridge immediately before use. Avoid touching the needle or treatment surface.
Install the cartridge according to your device instructions. Depending on the model, this may involve inserting, aligning, twisting, or locking the cartridge into position.
Never force a cartridge that does not fit correctly.
Make sure the cartridge is securely installed before operating the device.
Many Dr. Pen models allow needle exposure to be adjusted directly on the device.
The available adjustment range varies by model. A maximum depth shown in the product specifications should not be interpreted as a recommended setting for every user or application.
For at-home cosmetic use:
Speed controls how quickly the cartridge operates.
Different Dr. Pen models have different motors and numbers of speed levels. The same numbered setting should not automatically be assumed to perform identically across different devices.
If you're new to your Dr. Pen, become familiar with its controls first and adjust settings gradually according to the product instructions.
The goal is controlled operation—not simply selecting the highest available speed.
Once your device and cartridge are prepared, divide the area into small, manageable sections.
During use:
Applying additional pressure is unnecessary. Allow the motorized cartridge to operate as designed and follow the technique recommended for your specific device.
Not every skincare product is appropriate for use during microneedling.
Use products that are suitable for your intended cosmetic routine and follow the instructions provided with both the device and skincare product.
Avoid assuming that every serum, cream, or active ingredient in your normal skincare routine is suitable for use during or immediately after microneedling.
In particular, keep your routine simple rather than combining multiple potentially irritating active ingredients.
After using a Dr. Pen, keep your skincare routine gentle while the skin settles.
General considerations include:
If you experience unusual or persistent irritation, discontinue use and seek appropriate professional advice.
Cartridges intended for single use should never be reused.
For every session:
Dispose of the used cartridge appropriately according to applicable local guidance.
The reusable device and disposable cartridge should be treated separately.
After use:
Never store your Dr. Pen with a used cartridge attached.
The maximum depth or speed available on a device is a specification—not a recommendation for every user.
Keep at-home settings conservative and follow your device instructions.
Single-use cartridges should be replaced after every session. Always begin with a new, sterile, sealed cartridge.
Dr. Pen cartridges are not universally interchangeable. Confirm your exact device model before purchasing replacements.
Maintain controlled movement and avoid pressing unnecessarily against the skin.
Keep your routine simple around a microneedling session rather than combining multiple potentially irritating ingredients.
Different Dr. Pen devices may use different motors, speed levels, depth controls, and cartridges. Settings shown for one model should not automatically be applied to another.
Do not use a microneedling device over visibly irritated, broken, or infected skin.
If you have a skin condition, a history of abnormal scarring, take medications that may affect your skin or healing, or are unsure whether microneedling is appropriate for you, consult a qualified healthcare professional before use.
Deeper or advanced microneedling techniques should be left to appropriately trained professionals.
There is no single schedule that applies to every Dr. Pen device, cartridge, setting, and user.
Frequency can vary depending on the cartridge type, device settings, individual skin response, and intended cosmetic routine.
Follow the instructions supplied with your specific device and cartridge rather than applying a schedule designed for another model or cartridge type.
If you're still choosing your first Dr. Pen, don't focus only on maximum speed or needle depth.
Instead, consider practical features such as:
A straightforward device that fits your routine may be more useful than a model with advanced features you don't need.
Learning how to use a Dr. Pen starts with three fundamentals: understand your device, choose a compatible cartridge, and prioritize hygiene.
Before each session, start with clean skin and a new sterile cartridge. Familiarize yourself with your device's controls, keep at-home settings conservative, use controlled technique, and keep aftercare simple.
Most importantly, remember that Dr. Pen models and cartridges are not all identical. Always check the instructions and compatibility information for your exact device rather than treating settings from another model as universal.
