12-pin
Targeted facial areas
An option to compare for focused work on localised, healed acne-scar texture or lines. Consider it when the plan centres on specific facial areas, rather than choosing a cartridge only by its pin count.

Dr. Pen A11 · elleinbeauty
A large touchscreen, adjustable settings and a place to pause between steps. The A11 brings practical control to a professionally planned microneedling session.
For those exploring care for uneven texture, fine lines or healed acne-scar appearance, choosing the right procedure matters as much as choosing the pen.
Standard original kit + 10 additional cartridges in your chosen type.
Genuine Dr. Pen device · Official website verification · Serum not included · For trained professional use

Start with your skin goal
Professional microneedling creates controlled punctures in the skin to stimulate its repair response. Common goals include improving the appearance of fine lines, uneven texture, visible pores, healed scars and stretch marks.
Consider a professional consultation about smoother-looking skin and a more even surface. Depth, area and technique need to be planned together.
These are changes in skin contour. They need assessment of scar type; a particular pin count cannot guarantee scar correction.
Flat post-acne colour marks differ from indented scars. Identify the cause before deciding whether microneedling is suitable.
Do not use over active acne, open wounds, infected or irritated skin. These are general uses of professional microneedling, not A11-specific clinical results. Read the American Academy of Dermatology overview.

Designed around the session
In its running state, A11 automatically pauses when returned to the inductive base and can restart when lifted. The stand gives the handpiece a defined resting place between steps.
The base is a pause aid. Keep the cartridge clear of skin when lifting the pen, and switch the device off at the end of a session.
The manual directs charging through the pen’s power interface. The inductive base is not presented here as a wireless charger.
The illuminated touchscreen displays the selected speed and puts labelled controls within view.
Choose from six speed levels. Turn the depth dial near the cartridge to adjust the marked needle length.
The three-slot cartridge connector and backflow-protection membrane support the A11 cartridge system. Use compatible, single-use cartridges.
A11 uses a rechargeable battery for cordless operation. Its screen is a control display; this model does not have a verified serum-dispensing or LED skin-light therapy function.
Choose your extra cartridge pack
The options below refer to the 10 additional cartridges supplied with your A11. Each pack contains one selected type. Numbered cartridges are microneedling options; Nano tips are positioned for surface skincare.
Targeted facial areas
An option to compare for focused work on localised, healed acne-scar texture or lines. Consider it when the plan centres on specific facial areas, rather than choosing a cartridge only by its pin count.
Full-face texture and fine lines
A useful first comparison for a broader facial plan covering uneven texture, fine lines, pore appearance or mild healed scarring. Consider this full-face option when several of these goals overlap.
Neck, décolletage and body-area planning
Compare when the planned area extends beyond a small facial zone, such as the neck, décolletage or thighs. It offers another cartridge layout for these areas, which still need their own settings and suitability assessment.
Larger-area texture care
Another option to compare for neck, décolletage or body-area work. Its selection scenarios overlap with 24-pin, so discuss which layout suits the planned technique rather than treating it as an intensity upgrade.
Healed acne-scar texture
Another numbered microneedling option to compare when healed acne-scar texture is the concern. Choose within an individual plan; its higher pin count alone does not establish better results or greater depth.
Surface skincare and glow
Compare for a surface-focused skincare session aimed at a smoother, fresher-looking finish. It belongs to the Nano category, rather than a treatment plan for indented scars.
Surface skincare in a square-tip format
An alternative Nano shape for a surface-focused skincare routine. Its goals overlap with Nano Round; the shape alone does not establish a different scar, pigmentation or anti-ageing result.
Quick comparison: focused facial work → compare 12-pin; a broader facial plan → compare 18-pin; neck or body-area planning → compare 24-pin and 36-pin; surface skincare → compare the two Nano formats. The 42-pin option also has a healed-scar positioning.
These references describe cartridge product positioning, not independent proof of results. Uses overlap. Pin count alone does not establish depth, comfort or effectiveness. Professional settings and suitability still need to be decided individually. Scalp-related goals require a separate assessment and do not imply guaranteed hair growth.
What arrives
10 additional cartridges of your chosen type.
Choose 12-pin, 18-pin, 24-pin, 36-pin, 42-pin, Nano Square or Nano Round. The additional pack is one selected type, not a mixed assortment.
Serum is not included.
Select your plug type and additional cartridge option before adding to cart. Available plug options are US, EU, UK, AU and KR.
Before your session
Review the manual and professional plan. Charge the pen, disconnect charging power and prepare a clean work area and suitable supplies.
Keep the pen off. Check a fresh cartridge’s sealed packaging, align its notch with the device mark and turn to lock as shown in the manual.
Confirm the cartridge, speed and depth before treatment. Keep the tip clear when lifting from the base. Use a new cartridge for every session.
This is a setup overview. It does not prescribe treatment depth, frequency or aftercare. Follow the supplied A11 instructions and your trained practitioner’s protocol.
A11 at a glance
Use cartridges explicitly listed for A11. The elleinbeauty replacement pack also lists M8s, A9 and A8S; a shared brand name alone does not establish compatibility with other pens.
Product documentation
The documents on file include A11 in their model lists: EMC conformity documents HUT20221205-E and PTC25062613901E-EM01, LVD document HUT20221205-L, and FCC Part 15 Subpart B verification CTEE22040059.
These concern electrical safety or electromagnetic compatibility. We have not independently authenticated the documents with their issuers. They do not establish treatment effectiveness or guarantee risk-free use.
Genuine Dr. Pen
Your A11 device can be checked through Dr. Pen’s security-code verification system.
If the result is unexpected, contact elleinbeauty before use. Replacement cartridges are not promised a separate website-verification code. Check the official verification instructions for repeat-check rules.
Questions before you choose
Yes. elleinbeauty supplies genuine Dr. Pen A11 devices. Check the security label on your device packaging through Dr. Pen’s official verification page before use.
Locate the packaging security label, scratch the designated coating and enter the revealed code at drpen.com/verify. If you use a supported QR code, check that the destination is the official drpen.com website. Keep the code private.
Dr. Pen currently permits up to three valid verifications per code, with 24 hours between successful checks. A repeat attempt can be affected by these limits. Read the result and the current verification rules before trying again.
Check for typing errors and confirm the website address. Keep the box, label, proof of purchase and a screenshot of the result, then contact elleinbeauty before use. A previous check needs investigation; do not judge authenticity from packaging alone.
We do not promise an individual website verification code on replacement cartridges. The machine’s packaging is the verification point for this kit. A cartridge without its own code is not, by itself, evidence that it is counterfeit.
The standard original A11 machine kit, including the pen, inductive base, cable, adapter, manual and original-box cartridges, plus 10 additional cartridges of your selected type. Serum is not included.
No. All 10 additional cartridges are the single type selected in your order: 12-pin, 18-pin, 24-pin, 36-pin, 42-pin, Nano Square or Nano Round. They are supplied in addition to the standard original kit.
Choose the plug that matches your destination’s socket: US, EU, UK, AU or KR. Check the supplied adapter label before connecting power, and do not force a plug into an incompatible socket.
No. Arrange suitable preparation, procedure and aftercare supplies separately. A regular cosmetic serum is not automatically suitable for use on skin undergoing microneedling.
Use the A11-compatible replacement cartridge pack. Confirm that the packaging specifically lists A11 compatibility and check the selected pin option and pack quantity.
Professional microneedling is used for the appearance of healed acne scars, fine lines, uneven texture, visible pores, uneven tone and stretch marks. These are general procedure uses, not a promise that A11 will deliver a particular result.
Do not needle inflamed pimples, pustules, broken skin or infected areas. Let active acne be assessed and controlled before considering a separate plan for healed acne scars.
No. Flat red or brown marks mainly involve colour, while indented scars involve a change in surface contour. They need different assessments; do not select a cartridge solely because both followed acne.
Start by comparing 12-pin for focused facial work and 18-pin for a full-face plan addressing texture or fine lines. This is product-selection guidance, not a prescribed depth or treatment. See the complete cartridge guide for all seven choices.
The A11 listings place 24-pin and 36-pin in overlapping larger-area scenarios, including neck, décolletage and body-area planning. The 42-pin listing also mentions acne-scar concerns. There is no universal ranking by pin count; match the option to the planned area and technique.
Both are surface-skincare options for a smoother, glowing appearance. Choose the tip format appropriate to the planned surface routine. Neither replaces a microneedling plan for indented scars, and one shape is not established as more effective than the other.
No. Pin count identifies the cartridge layout. The depth dial is a separate control, and outcomes also depend on technique, skin condition and the treatment plan.
Some A11 cartridge guidance includes scalp-area use. Hair loss needs its cause assessed before any procedure; this device or a particular cartridge is not a guaranteed hair-growth treatment.
The large illuminated interface provides visible speed information and labelled controls for speed and power/start-pause operation. The A11 has six speed levels. Needle length is adjusted separately with the dial near the cartridge.
When an operating A11 is placed on its inductive base, it pauses automatically. Lifting it from the base can restart it. Keep the cartridge clear of skin when lifting, and switch the device off when a session is finished.
The A11 manual describes it as an inductive pause/rest base and directs charging through the pen’s power interface. Charge with the supplied cable and adapter as instructed; do not assume resting the pen on the base charges it.
Yes. It has a rechargeable built-in battery for cordless operation. Charge before the session and disconnect from charging power before use.
Use the pen disconnected from charging power. Listings differ on wired operation; follow the supplied A11 instructions rather than assuming it supports treatment while connected.
The device provides six speeds and a marked needle-adjustment range of 0–2.5 mm. These are hardware capabilities, not a recommended treatment setting. A trained practitioner should select settings for the area, cartridge and individual skin.
A11 is a microneedling pen with a control display. It has no verified built-in serum reservoir, automatic dispensing, LED skin-light treatment, RF or EMS function. The illuminated screen is for controls.
Pause and keep the cartridge away from skin. Check whether the pen is resting on its base and whether it needs charging. If it still runs irregularly, becomes unusually hot or will not operate normally, switch it off and contact elleinbeauty. Do not open or repair the pen yourself.
The current Dr. Pen A11 brand page specifies trained professional use. Easy-to-read controls do not replace training or a suitability assessment. Arrange professional guidance before purchasing for a procedure.
Read the supplied manual, inspect the pen and adapter, and prepare a clean workspace. Check the cartridge type, expiry information, packaging seal and condition. Do not use a damaged, expired, previously opened or contaminated cartridge.
With the pen switched off, align the cartridge notch and device mark, insert gently and turn to lock as shown in the A11 manual. Check that it is secure before starting. Do not force an incompatible cartridge into the connector.
No. Use a new single-use cartridge for every session, including for the same person. Do not share it or try to make a used cartridge reusable by soaking it in alcohol.
Do not treat alcohol soaking as a way to sterilise or restore a cartridge. Published preparation advice differs; follow the instructions supplied with your sealed cartridge and your practitioner’s infection-control protocol. Ask for clarification before use if they conflict.
Switch off and disconnect power. Remove the used cartridge and dispose of it safely under local sharps requirements. Wipe the pen exterior as instructed, keep liquid out of the connector and store the device dry. Do not immerse the pen.
Discuss your skin and medical history, medications and any tendency to form raised scars with a qualified healthcare professional. Active skin disease, infection, impaired healing or bleeding concerns may change whether a procedure is appropriate.
No. Discomfort, redness, swelling or flaking can occur. Infection, pigment change and scarring are possible, especially with unsuitable use. Recovery depends on the procedure and individual skin.
There is no single schedule for every area, cartridge or skin concern. Let the practitioner plan the interval and aftercare; do not repeat a session on skin that has not recovered.
Improvement can be gradual and may need a course of treatment. Neither immediate redness nor a deeper setting proves better results. No specific timeline or percentage improvement is guaranteed.
Follow the aftercare plan for the actual procedure. Ask when to resume makeup, exfoliating acids, retinoids and other active products. Protect recovering skin from sun exposure; seek medical care for severe, persistent or worsening reactions.
Contact elleinbeauty support with your order number, the selected pack and plug, and clear photos or a short fault video. Keep the packaging while the issue is reviewed. Do not post your full security code publicly.
Please read elleinbeauty’s current shipping policy and refund policy. Contact support before returning an item or opening sterile consumables if you are unsure about eligibility.
Dr. Pen’s current A11 information specifies trained professional use. Microneedling punctures the skin and needs suitable training, hygiene and aftercare. Ask a qualified healthcare professional whether it is right for your skin and goals.
For general procedure preparation and recovery, see Cleveland Clinic’s microneedling overview. Device and cartridge instructions take priority over general product-selection guidance.
