Dr. Pen At Home Kit: What's Actually in the Box — and What You Still Need

A Dr. Pen device box contains the handpiece, a charging set, a user manual and two cartridges — and none of it decides what goes on the skin, how many heads a course will take, or what the days afterwards need.

Four things a home session needs are not in the box: enough heads to finish the course, a formulation made for an open channel, numbing if the depth you chose calls for it, and aftercare supplies. Both are answered below.

A kit is not measured by how many items are in the box, but by whether it lets one session do four things in the right order: open the channels, keep the wound clean while it is open, put something useful into it, and let the barrier recover.

What is actually in the box

Every device box in the range carries the same three categories of item — the handpiece, a way to charge it, and a sealed head to start with. What differs is the accessories and how many heads are included.

Model	In the box	Depth range
Dr. Pen M8S	Pen, USB cable, charging adaptor, user manual, 2 cartridges	0–2.5 mm
Dr. Pen A11	Pen, 2 cartridges, A11 inductive base, USB cable, charging adaptor, user manual	0–2.5 mm
Dr. Pen A10	Storage box, pen, adaptor and USB cable, 2 × 12-pin cartridges, instruction manual	0.25–2.5 mm

Two cartridges is a starting quantity rather than an oversight: it is enough to run two sessions and learn how the pen behaves on your own skin before committing to a pack of heads. The heads do not cross between models, so the cartridge guide is worth reading before the pen is ordered rather than after.

What the box does not include

Four purchases sit outside every device box in the range, and three of them are not sold as part of any device listing at all.

• A head for every session you intend to run — a head is used once, so the two in the box are two sessions. Replacements are a separate order, and they are not interchangeable between models of pen.
• A formulation made for an open channel — sealed and sterile. Only the named kits add one, and our serum guide sets out the difference between a preparation made for this use and a cosmetic that merely sounds like one.
• Numbing, if your protocol sits at the deeper end — sensation, bleeding and recovery time all track depth, so the question is decided by the depth you chose rather than by the pen.
• Aftercare supplies — a fragrance-free cleanser, a plain moisturiser and daily sun protection, on hand from the start rather than bought in reaction to the first session.

What is not missing is depth range: every pen reaches past what a home routine should use, and the 1.5 mm ceiling is a boundary rather than a specification worth paying for.

How far a box of heads actually goes

The arithmetic is simple because the single-use rule removes the variable: one head, one session.

• Two heads is two sessions — under a month at the fortnightly cadence published for shallow facial work, and about two months at the monthly cadence published for scarring work.
• Twenty heads is twenty sessions — roughly nine months at fortnightly spacing, or well over a year at monthly spacing.
• A year needs twelve to twenty-six heads — twelve to thirteen at monthly spacing, around twenty-six at fortnightly spacing, depending on which protocol you are running.

Set the head count by the protocol you intend to run, and the protocol by the area you are treating.

What a bundle or a kit adds to that

• A cartridge pack, on eight models — a second listing keeps the device box and adds twenty heads. These are the M8S, A11 and A10 listings, among others.
• A sterile formulation, on three — these are the only listings that answer the formulation gap, which a device box cannot answer at all: the M8S collagen regeneration kit, the acne scar kit and the scalp care kit.
• Storage and charging — the A10 ships with a storage box, and the A11 with an induction base that holds and charges the handpiece. Neither changes a result; both change how often the pen is where you left it.

Pack size and pin options differ across those eight, so read the contents note on the page rather than the title.

What to check before you order

Once the routine is settled, three practical checks remain — none of them about which pen performs best.

• The head family is the decision you cannot undo — the M8S and A11 draw on the same family across the A8S and A9, while the A10 has its own. Changing pen later means changing head range with it, so if that choice is still open, start with how to choose a Dr. Pen device.
• A finer starting point matters more than a higher ceiling — home work lives between 0.25 and 1.0 mm on the face, so a gauge that starts at 0.25 mm gives more usable range than one that reaches further than you should go.
• Power and accessories change convenience, not results — cordless and wired options differ by model, and neither changes what a session does.

What a home session asks the skin to do

Microneedling is a controlled injury. A head carrying fine needles opens channels through the epidermis and into the upper dermis — the layer where collagen and elastin are produced. The change does not come from the needles themselves but from the repair response those channels trigger, and that response runs on a timeline of weeks, not minutes.

• Depth decides whether the signal reaches the dermis at all — set too shallow and the channels stay in the barrier, so depth matters more than any other control on the pen.
• The channels are short-lived — they stay open for hours, not days, which is why what you apply, and when, is part of the treatment rather than an afterthought.
• The visible change is the end of the process, not the start — the collagen response builds over roughly eight to twelve weeks, so one session produces very little and a course produces the result.
• None of this changes with the pen you hold — the response is the same for every device.

The requirements a home routine has to meet

Read that back as a set of requirements, and the gaps in the box stop looking like optional extras. Five follow, and only two can be met by anything that ships with a pen.

• A clean surface and clean hands — sunscreen, make-up and surface oil come off first. Needling through a film of product pushes that film into the channel.
• A head that has never touched skin — the tip is the only part that enters the wound, so sterility is per head and per session, not per device.
• A depth matched to the zone — the face is not one thickness. Skin around the eyes is among the thinnest on the body; the back and thighs are several times thicker, so one depth cannot suit both.
• A formulation that belongs in an open channel — sealed, sterile, and made for this use. A jarred cosmetic is not sterile to begin with, and its preservatives were never designed to go below the barrier.
• A planned recovery — what happens in the days after a session either supports the repair response or interferes with it.

Why a head is used once

Three things degrade a head after a single session, none of them visible to the eye.

• The tip deforms — micro-fine points that have been through skin no longer cut cleanly, so a worn head drags across the surface instead of opening a channel.
• Residue stays in the array — blood and skin cells lodge between the pins, where no home rinse reaches, and damp gaps are where bacteria multiply.
• The mount wears — repeated removal and reseating stresses the connection, and a head that shifts makes your depth setting unpredictable.

Deeper sessions carry most of this, because the deeper the channel, the more direct the route for anything carried into it. A systematic review of needling's adverse effects records what the hygiene rules exist to prevent. Practical detail on what degrades before it shows is in our single-use explainer.

Why sessions are spaced weeks apart

The interval is not a preference or a pack-size decision; it is the time the repair response needs before the same area is asked for another one.

• Delicate areas and shallow facial work — 0.25–0.5 mm, every 1–2 weeks.
• Texture and enlarged pores — 0.5 mm, every 2–3 weeks.
• Pitted scarring — 0.5–1.0 mm, every 3–4 weeks.
• Body work — 1.0–1.5 mm, every 3–4 weeks.

Going back over the same area before the previous response has matured adds injury without adding signal. Repeated application has itself been studied for its effect on barrier function and on markers of infection and inflammation — in a mouse model, disclosed as such. The figures above are our own published depth chart.

What the skin needs after a session

• Fragrance-free cleansing and a plain moisturiser for the first days, and nothing with acids, retinoids or exfoliants while the barrier is rebuilding.
• Daily sun protection, because a pigment response to injury is the single most common way a home routine makes things look worse rather than better.
• No second procedure on the same area until it has settled, including another needling pass.
• One step at a time — a post-treatment skincare protocol has been studied as a scheduled part of the procedure, with a defined sequence, rather than as a set of products added on impulse.

What goes into the channels is the one part of the routine where the wrong purchase is worse than no purchase — which is why the formulation is a gap rather than an extra.

Who should not run this routine at home

This is the part no contents list can answer, and it is worth settling before anything is ordered.

• Breakouts or broken skin in the treatment area — needling over active inflammation spreads it, and it can leave the mark worse than the one you started with.
• Recent sun exposure, a burn, or skin that is still warm and tender — pigment-producing cells respond to injury by producing more pigment.
• A skin condition that a clinician is already treating — the plan belongs to them, and needling changes what they are assessing.
• A history of raised or keloid scarring — the same repair response that makes needling useful is the one that overproduces scar tissue in some people.
• Anything you would be guessing about — a mole or patch that has changed in size, shape or colour is a clinician's question, not a microneedling one.

What this article does not cover

• It does not compare Dr. Pen with other brands or with clinic treatment. The professional-versus-home comparison is a separate article.
• It does not publish prices or totals — they change, and the order of decisions here is about requirements rather than spend.
• It does not set out session technique. The sequence from preparation through aftercare is its own guide.
• It does not replace a clinician's assessment of your skin. Nothing on this page can see the skin it is describing.

Where to go next

Our how to verify your Dr. Pen page sets out the checks to run on the device and its packaging, and they are worth running before a first session rather than after. The full sequence is in how to use a Dr. Pen at home, and the depth and interval for every area is in the needle depth chart.

Frequently asked questions

How do I know whether at-home needling is working?

Judge it at three months, not at three days. The visible change is the end of a repair cycle rather than the result of any single appointment, so the honest checkpoints are texture under the fingers, how make-up sits, and whether the rhythm you chose is one you can still keep to. A session that looks like nothing happened is the expected result, not a failed one.

What should I not put on my skin in the days after a session?

Treat the first days as an exclusion window rather than a routine. Nothing with acids, retinoids, fragrance or alcohol until the surface has settled, and no second procedure on the same area while it is still recovering. Cleansing, moisture and daily sun protection are the whole of it until then.

How deep can I safely go at home, and where?

Our home range tops out at 1.5 mm, and most facial work sits at or below 1.0 mm; delicate zones are shallower still, where even 0.25 mm is a considered choice. Depth is decided by the area rather than by the person, which is why we publish an area-by-area pairing instead of a single number.

Do I need to buy a serum separately, or is one included?

On a device box, and on a bundle, you buy it separately. Only the named kits include one — the M8S collagen regeneration kit, the acne scar kit and the scalp care kit each pair the device with a sterile preparation made for this use.

Can I use the kit on areas other than the face?

Yes. The same handpiece runs body zones at settings deeper than the face should carry and with longer intervals between passes, and the depth chart pairs each area with both numbers.

Do I need numbing cream for an at-home session?

Not at shallow depths. Sensation tracks depth more closely than it tracks the device, so a 0.25 mm pass and a 1.0 mm pass are different experiences — if your protocol sits at the deeper end, it is worth having on hand from the start.

How many cartridges does a first year of at-home sessions need?

It depends on the interval. A year at monthly spacing needs twelve or thirteen; at fortnightly spacing, closer to twenty-six. One pack of twenty therefore covers the first case with room to spare and falls short of the second.

What should be kept with the kit between sessions?

The pen body, wiped and dry; the charging set; unused cartridges still in their sealed packaging; and a fresh head ready for the next session. A head that has been used is finished — sealed packaging is what keeps an unused head sterile, and that cannot be recreated at home.
