How Often to Microneedle, and Why More Is Not Better
Depth sets the interval, not ambition. Weekly at home, several weeks in clinic, and the honest reason frequency is the worst lever to pull.
How often you should microneedle is set by depth, not by ambition. A home cosmetic device at shallow settings runs on a weekly schedule, and clinics space treatment depth work several weeks apart for the same reason.
Both numbers are correct, and they answer different questions. This page explains what actually sets the interval, what changes if you shorten it, and why raising frequency is the least useful thing you can do with the time.
The short answer, by device
Read the last column as the reason. Frequency is downstream of how much the skin has to close.
| Situation | Commonly used interval | What sets it |
|---|---|---|
| re:tones MTS at home | One session every seven days | The instruction re:tones publishes for this device |
| Home devices at very shallow settings | Often described as weekly or twice weekly | Shallow work, minimal closing to do |
| Home devices in the middle of a collar range | Usually every one to two weeks | Deeper travel, more to settle |
| Clinic microneedling at treatment depth | Commonly four to six weeks apart | Wider needles, deeper travel, managed downtime |
Notice the pattern. The interval stretches as the needle goes deeper and wider. A clinic is not being cautious for its own sake, and a weekly home schedule is not a shortcut around a rule.
How often to microneedle at home
One session every seven days is the cadence re:tones specifies for the MTS. It is a device instruction rather than a biological law, and it exists because the failure mode of home devices is overuse.
The 5D-Nano cartridge runs an 8 µm needle and the R-Nano runs 15 µm, on a collar that travels 0.5 to 1.5 mm with no clicks or stops. That is a shallow, fine arrangement compared with a clinic pen, and it still gets a full week between sessions. The full specification list sits on the MTS device record.
There is a second, plainer reason for a week. Cartridges are sterile and single use, so every session costs a consumable. Three ship in the box, which is three weeks before you reorder.
Why the gap exists at all
A session opens temporary channels through the outer layer of your skin. That layer spends the days afterward doing its actual job again, which is keeping things out.
The gap is not recovery theatre. It is the part of the cycle where the barrier goes back to being a barrier. Start the next session before that finishes and you are needling skin that never got back to baseline. What that week actually looks like is set out hour by hour.
Nobody has published a closure figure for an 8 µm needle, and re:tones states none. The closest human work, Gupta, Gill, Andrews and Prausnitz in the Journal of Controlled Release in 2011, found uncovered skin resealed within two hours on needles far wider than a fine home array. Surface resealing and a barrier back at full strength are not the same milestone, which is exactly why the schedule is weekly rather than hourly.
What going too often actually looks like
The signs are unglamorous and they arrive in a predictable order.
Colour that stops settling
The first session fades by the next morning. The fourth one in ten days does not. Redness that is still there when the next session comes around is the clearest signal available, and it is telling you to stop rather than to be gentler.
Products that suddenly sting
A moisturiser you have used for two years starts to burn. That is not the moisturiser changing. It is a barrier that has not been allowed to finish closing, so ordinary formulas are meeting skin they were not written for.
Dryness and flaking that will not resolve
Persistent tightness and flaking are commonly described as barrier disruption rather than progress. If that is where you are, the fix is time and a plain routine, not another session. The sequence is in how to repair a damaged skin barrier.
A rising infection risk
An opening in skin is an opening for everything. More sessions means more openings, more cartridges handled and more chances for the one time you cut a hygiene corner.
More is not faster, and here is the honest version
Frequency feels like effort, so it is the first lever people reach for. It is also the lever with the worst ratio of upside to risk.
re:tones will not tell you that two sessions a week doubles anything, since it has run no clinical study and no consumer panel. It publishes no efficacy percentage, no absorption multiple and no time to result. What it publishes instead is the mechanism and the list of things it has not measured, on the science and claims record.
Any brand offering you a frequency that produces a faster outcome should be asked which study produced it, with how many people, over how long. That question ends most of these conversations.
Move these three instead of frequency
You have three controls on the MTS and they sit in three different places. None of them is a calendar.
- Depth. The collar on the body, continuous from 0.5 to 1.5 mm. Move it between sessions, never inside one.
- Intensity. The button on the body, six levels, shown on the display. It changes the rate, not the travel.
- Flow. A ring on the cartridge with three positions, setting how much ampoule the tip releases.
Change one at a time, then wait a week and see what happened. Two changes at once means you learn nothing from either. What each depth position sits against in published anatomy is laid out in the depth guide.
The first four weeks, as published
re:tones publishes a ramp rather than a starting setting, and the ramp moves depth and intensity together over weeks rather than inside a session.
| Week | Depth | What the week is for |
|---|---|---|
| Week 1 | 0.5 to 0.75 mm | Meeting the device. How it feels, not what it does. |
| Week 2 | 0.75 to 1.0 mm | A little longer, on the upper face. |
| Week 3 | 1.0 to 1.25 mm | General facial use across cheeks, forehead and jaw. |
| Week 4 onward | 1.25 to 1.5 mm on resilient areas | A full session, deeper end kept for areas that take it. |
Step up only once the previous week was uneventful. A week that was not uneventful is a week you repeat, and repeating a step costs you nothing but time.
When to skip a week entirely
Skip the session if any of these apply on the day.
- Skin is still reactive, pink or tight from the last one
- You have an active breakout, a cold sore, or any inflamed lesion
- You are sunburnt, or your skin is still warm from sun
- You started a retinoid, an acid or a new prescription this week
- You have a professional treatment booked in the next few days
The schedule serves your face, not the other way round. A skipped week has never cost anyone anything.
Frequency near the eyes and on thin areas
Skin thickness across one face varies by close to a factor of two in published ultrasound means. Weekly on a cheek and weekly around the eyes are not the same request.
Treat thin areas as a separate calibration with their own pace, and include them less often rather than more shallowly only. What changes there is covered in microneedling under the eyes.
What the interval cannot tell you
A schedule is a device instruction. It is not a promise, and four things stay outside it.
- How deep the needle went. Skin deforms under a tip, so a set depth is not a reached depth.
- How long your channels stayed open. Not measured for this device, and no figure is published.
- How much of anything crossed. Not measured, and not claimed.
- What it will do for you. No percentage, no timeline, no panel.
Anything you would describe as treatment rather than routine belongs with a dermatologist. The MTS is a cosmetic device. It is not a medical device and is not intended to diagnose, treat, cure or prevent any disease.
New to the category? Start with what microneedling is and what it does to skin. If you want the two days after a session rather than the weeks around it, read the 48 hour aftercare rules.
Frequently asked questions
How often should you microneedle at home?
Once every seven days on the MTS, which is the cadence re:tones publishes for it. Deeper settings do not earn a shorter gap, and a shallower setting is not a licence for a second session midweek. Skip the week entirely if your skin is still reactive.
Can you microneedle twice a week?
Not on this device, and not on any device you are running in the middle of its depth range. Twice weekly appears in guidance for very shallow work only, and the most common self inflicted problem in home microneedling is frequency rather than depth.
How long should you wait between microneedling sessions?
A full seven days at home, and commonly four to six weeks for clinic work at treatment depth. The gap tracks how far and how wide the needle travelled. Count from the session, not from the day the redness left.
Is it bad to microneedle every day?
Yes. Daily use gives the barrier no interval in which to be a barrier, and the usual results are colour that stops settling, products that start to sting, and a rising infection risk. No home device instruction supports it.
How many microneedling sessions before you see anything?
re:tones publishes no time to result, because it has measured none. Any number you are given for a home device should come with a named study, a method and a sample size. Without those it is decoration.
Can you microneedle more often at a shallow depth?
Shallow settings do shorten the interval in general guidance, and on the MTS the schedule stays weekly regardless of where you set the collar. Depth and frequency are separate controls, so treat a shallow week as a shallow week rather than as spare capacity.
