How often can you microneedle?
Last updated:
In published clinical trials, professional microneedling sessions were spaced 2 to 6 weeks apart, often about a month, in courses of three to six sessions. Results build for months after a course, and a 2024 review describes maintenance sessions every 6 to 12 months. The practitioner sets the interval for the device, the needle depth and how your skin recovered from the last session.
How far apart should microneedling sessions be?
Clinical trials have used intervals from 2 to 6 weeks1. A 2025 meta-analysis of acne scar trials found courses of three to six sessions spaced 2 to 6 weeks apart1. Roughly monthly spacing appears often: four sessions 30 days apart for facial aging4, three monthly sessions for acne scars5 and sessions at 0, 4 and 8 weeks for melasma5.
Shorter intervals have also been tested under clinical supervision2,3. In one randomized trial, patients with acne scars had microneedling every two weeks for 12 weeks2, and in a double-blind trial, four sessions were performed 20 days apart3.
| Study and concern | Sessions | Interval |
|---|---|---|
| Randomized trial, atrophic acne scars, 60 patients2 | Every two weeks for 12 weeks | 2 weeks |
| Double-blind trial, atrophic acne scars, 120 patients3 | 4 | 20 days |
| Open-label study, facial aging, 48 patients4 | 4 | 30 days |
| Randomized trial vs laser, acne scars, 46 patients5 | 3 | Monthly |
| Trial with topical tranexamic acid, melasma, 60 patients5 | 3 | Weeks 0, 4 and 8 |
| Microneedling plus 20% TCA peel, acne scars1 | 4 | 6 weeks |
| Meta-analysis of nine acne scar trials1 | 3 to 6 | 2 to 6 weeks |
In North America, searches about microneedling frequency peak in January and are lowest in September, and a course started in winter keeps more sessions away from summer sun, which matters because FDA lists a tan, or sun planned in the two weeks after a session, as a reason to wait8. In the Southern Hemisphere, the same lower-sun window falls from about May to August.
Why do you have to wait between sessions?
Each session makes many small punctures, a controlled injury that sets off the skin's healing process7,8. Redness usually appears right after the procedure and lasts from a few hours to a few days, and mild swelling generally subsides within a few days7. FDA describes bleeding, bruising, redness, tightness, itching and peeling that typically go away without treatment after a few days or weeks6.
The visible change comes later than the redness4,7. A 2024 review notes that collagen remodeling continues for months after treatment, leading to gradual improvement7. In a study of four monthly sessions for facial aging, wrinkles, laxity and texture had improved significantly by day 90 and further at day 150 after the first treatment4.
Pigment change can take longer to settle7. Post-inflammatory hyperpigmentation, darkening of the treated skin, is more common in darker skin types and usually resolves within a few weeks7.
How many microneedling sessions do you need?
Usually several8. FDA notes that you may need more than one procedure to get the desired aesthetic improvement8. Acne scar trials ran three to six sessions1, and one trial found that improvement correlated with the number of sessions and fell with older age and longer scar duration1.
Results also fade6. FDA says any improvement in appearance may be temporary and that maintenance may require additional procedures over time6. A 2024 review reports that results can last several months to years, that aging and sun exposure affect how long they hold, and that many patients benefit from maintenance treatments every 6 to 12 months7.
Can you microneedle at home every week?
Home products are a different category from the devices in these trials6. FDA has not authorized any microneedling medical device for over-the-counter sale, and dermal rollers with short, blunt needles that claim only to remove dead skin and smooth the skin are generally not medical devices6. The schedules in the table come from professional procedures, not from home products1,2,4.
For a home product, follow its directions, and clean it between uses as the manufacturer directs without sharing it with anyone6.
When should you skip or postpone a session?
FDA lists conditions in which microneedling may not be suitable, several of them temporary reasons to wait8, and trial experience adds sun exposure during a course1:
- An active skin infection, an active rash on the face or a cold sore outbreak8
- A tan, or sun exposure planned in the two weeks after the procedure8
- Isotretinoin now or within the past 6 months8
- Pregnancy or breastfeeding8
- Sun exposure during a course: in one combination trial, two participants withdrew after transient facial discoloration following sun exposure1
Key takeaways
- Clinical trials spaced microneedling sessions 2 to 6 weeks apart, often about monthly.
- Courses in acne scar trials ran three to six sessions.
- Redness and swelling settle in days, but collagen remodeling continues for months.
- Maintenance every 6 to 12 months is described in a 2024 review, and FDA notes results may be temporary.
- Home rollers with short, blunt needles are a different category from the professional devices behind these schedules.

Frequently asked questions
Is microneedling every two weeks too often?
How soon do you see results from microneedling?
Can you use retinol between microneedling sessions?
Ask your provider first. FDA advises asking how to care for skin after microneedling because it may be more sensitive to the sun and to products containing retinol, glycolic acid, menthol, capsaicin or alcohol6.
