A Dermapen is an electric microneedling device. A replaceable cartridge fitted with fine needles creates controlled microchannels in the skin. This action triggers natural repair mechanisms, supports processes associated with collagen and elastin production, and may improve the delivery of sterile professional formulas specifically intended for microneedling.
The device can be used on the face, neck, décolletage, body and scalp. Needle depth and operating speed are selected according to the treatment area, skin condition and professional protocol. Intensive procedures that disrupt the skin barrier should only be performed by a qualified practitioner.
What is a Dermapen in simple terms?
The device is shaped like a large pen. A motor inside the body moves the cartridge needles rapidly in a vertical direction. The practitioner can adjust both speed and needle extension, allowing one device to treat small, precise areas as well as larger body zones.
Unlike injectable mesotherapy, a Dermapen does not inject a product with a syringe. It creates multiple controlled microchannels. Only sterile professional products that are explicitly suitable for microneedling should be used during the treatment. Everyday skincare is not intended for application to compromised skin.
In short: a Dermapen is the device, while microneedling—sometimes referred to as fractional mesotherapy—is the procedure performed with it.
How does microneedling work?
- A single-use cartridge creates microchannels at the selected depth.
- The skin recognises the controlled stimulus as a signal to repair.
- Processes linked to collagen and elastin synthesis are activated.
- The skin surface gradually renews during the recovery period.
- After a course of treatments, texture and tone may appear more even.
Results depend on the initial skin condition, age, area, treatment intensity and aftercare. Microneedling does not remove wrinkles or scars instantly; tissue remodelling is gradual and individual.
What is a Dermapen used for?
- uneven texture, dull-looking skin and enlarged pores;
- fine lines and reduced firmness;
- uneven tone and superficial pigmentation;
- post-acne marks and selected atrophic scars;
- stretch marks and visible signs of photoageing;
- professional scalp-care programmes.
A Dermapen is not a universal treatment for skin disease. Active acne, herpes, infection or significant irritation should be assessed by a dermatologist first. Needling inflamed lesions may worsen the condition and spread infection.
Dermapen vs derma roller: what is the difference?
A derma roller has needles fixed to a rotating drum. They enter and leave the skin at an angle, and their length is usually fixed. Dermapen needles move vertically, while depth and speed can be adjusted. This makes precise treatment of small areas easier and allows one device to be adapted to several zones.
- adjustable needle extension;
- multiple speed settings;
- vertical motion and consistent channel density;
- a choice of cartridges for different protocols;
- a new sterile single-use cartridge for every treatment.
How to choose a Dermapen
Needle-depth range
Different areas require different levels of intensity. A model with smooth adjustment from approximately 0.25 to 3 mm provides flexibility. The maximum setting is not suitable for every area or client; a trained professional must determine the safe working depth.
Speed and power supply
Several speed levels help adapt the device to the technique and treatment area. Cordless operation provides freedom of movement, while optional mains operation can be useful in a busy salon.
Display and cartridge availability
A display makes it easier to monitor speed and battery level. Before buying, check cartridge compatibility and long-term availability. Every cartridge must be sterile, sealed, single-use and opened immediately before the treatment.

Safety, contraindications and aftercare
Microneedling disrupts the skin barrier, so a cartridge must never be reused—even on the same client. Protect the device body with a barrier sleeve and disinfect it according to the manufacturer’s instructions.
Do not perform microneedling over active inflammation, bacterial or fungal infection, active herpes, open wounds, clotting disorders or in clients prone to keloid scarring. Pregnancy, breastfeeding, certain medications, chronic illness and autoimmune conditions require prior medical advice.
After treatment, avoid touching the skin with unwashed hands. Temporarily discontinue acids, retinoids and irritating formulas, and avoid saunas, swimming pools, tanning and strenuous exercise. Use the recommended soothing care and daily sun protection. Do not pick flaking skin or scabs.
Frequently asked questions
Can a Dermapen be used at home?
Very superficial home use should only be considered after professional advice and with strict adherence to the instructions. Scars, stretch marks, problematic skin and deeper settings require a trained practitioner.
How many treatments are needed?
The number of sessions and the interval between them are determined individually according to skin condition and treatment intensity. Recommended recovery intervals should not be shortened.
Which cartridges should I choose?
The configuration depends on the area and protocol. Nano tips are used for superficial cosmetic treatments, while needle cartridges are intended for classic microneedling. Compatibility, sterility and single use are essential.
When choosing a Dermapen, compare depth range, speed, battery life, ergonomics and cartridge availability. The F7S is a practical choice when low weight and versatility matter, while the F8S is better suited to more intensive professional use and larger areas. You can buy a Dermapen from A4PMU and select compatible consumables. Complete relevant professional training and follow hygiene requirements before performing treatments.
