What Is RF Microneedling?
RF microneedling (radiofrequency microneedling) is an in-office skin procedure that uses an array of tiny needles to deliver radiofrequency energy into and under the skin, where it creates heat. The needle punctures and the heat prompt the body to make new collagen. RF microneedling is used to treat wrinkles, acne scars and loose skin.
RF microneedling devices are Class II medical devices cleared by the FDA. Morpheus8 and Infini are two brands. The FDA calls RF microneedling a medical procedure, not a cosmetic treatment, and says the devices should not be used at home.

| How it's given | In a medical office after numbing cream. About an hour per session. |
| Sessions | Typically two to four |
| Results | Best about 3 to 6 months after the first treatment |
| Downtime and side effects | About a day of redness. Possible swelling, pinpoint bleeding and mild bruising. |
| FDA status | Devices are FDA-cleared. The FDA issued a safety communication in October 2025. |
How Does RF Microneedling Work?
RF microneedling works by combining two controlled injuries: needle punctures and heat delivered at set depths within and under the skin. Radiofrequency energy is a type of electrical energy that creates heat in tissue.
- Heat: the thermal injury remodels the dermis, adding a tightening effect beyond traditional microneedling.
- Insulated needles: some devices insulate the needles to focus heat in the dermis and spare the skin's surface.
- Collagen: new collagen forms slowly. A review of 42 higher-quality studies found that skin kept improving even 6 months after treatment.
What Does RF Microneedling Treat?
RF microneedling is used mainly for wrinkles, depressed acne scars and early skin sagging.
- Wrinkles: the FDA has cleared RF microneedling devices to treat facial wrinkles.
- Acne scars: the American Academy of Dermatology (AAD) says combining radiofrequency with microneedling can make acne scars less noticeable than either treatment alone.
- Loose skin: in a study of 30 adults treated on the lower face, jawline and neck, clinicians and patients rated results as highly improved.
The AAD notes that skin tightening works best for people with a small amount of sagging who keep a stable, healthy weight, don't smoke and protect their skin from the sun.
What to Expect Before, During and After RF Microneedling
Each RF microneedling session takes about an hour, and redness usually lasts about a day.
- Before: tell your provider about blood thinners, isotretinoin use and cold sores. Avoid alcohol and NSAID pain relievers, which can increase bruising.
- During: numbing cream is applied first. In a study of 30 adults, the average pain score was 5.61 out of 10.
- After: most people resume normal routines within a day. Skip makeup for 24 to 48 hours, avoid the sun for 2 weeks and sleep with your head raised for 48 to 72 hours after facial treatment.
RF Microneedling Results and How Long They Last
RF microneedling results appear gradually as new collagen forms, with the best results typically 3 to 6 months after the first treatment. In one study, sessions were spaced 4 to 12 weeks apart. RF microneedling can't match the results of surgery.
The FDA notes that any improvement from microneedling may be temporary, and maintenance may require more procedures over time.
RF Microneedling Risks and Side Effects
RF microneedling usually causes mild, short-lived side effects, but the FDA has received reports of serious injuries.
- Common: redness, swelling, pain, pinpoint bleeding and bruising.
- Less common: temporary dark spots (post-inflammatory hyperpigmentation), acne or cold sore flares, track marks and infection.
- Serious: on October 15, 2025, the FDA warned of reported burns, scarring, fat loss, disfigurement and nerve damage, some needing surgical repair. An analysis of FDA reports from 2020 to 2025 found that fat loss, scarring and lingering redness were the most often reported problems.
Who Shouldn't Have RF Microneedling?
RF microneedling may not be suitable during pregnancy or breastfeeding, based on the FDA's advice for microneedling devices. Other reasons to avoid or delay treatment include:
- A bleeding disorder or blood-thinning medicine
- A weakened immune system or uncontrolled diabetes
- An active skin infection, rash or cold sore outbreak
- Eczema, psoriasis, vitiligo or an autoimmune disease
- A history of keloid scars
- A tan, or planned sun exposure in the 2 weeks after treatment
RF Microneedling vs. Microneedling and Laser Resurfacing
RF microneedling adds heat to standard microneedling and needs far less downtime than laser resurfacing.
| How it works | Downtime | Course and notes | |
|---|---|---|---|
| RF microneedling | Needles plus radiofrequency heat | About a day of redness | Two to four sessions |
| Microneedling | Needle punctures alone | Redness for a few days to a week | For acne scars, 3 to 5 sessions every 2 to 4 weeks |
| Laser resurfacing | Laser resurfaces the skin | 5 to 7 days at home | Most effective nonsurgical tightening, with greater scarring risk |
For acne scars, a 2025 systematic review of 16 studies (481 patients) found RF microneedling about as effective as some fractional lasers, with shorter downtime.

RF Microneedling FAQs
Is RF microneedling safe?
RF microneedling is usually well tolerated, with mild, temporary side effects, but serious complications have been reported. In October 2025, the FDA warned of reported burns, scarring, fat loss, disfigurement and nerve damage, some needing surgical repair. An analysis of FDA reports from 2020 to 2025 found 86 reports involving 145 adverse events. The FDA recommends a licensed provider with RF microneedling training and experience, and says the devices should not be used at home.
How many RF microneedling sessions do you need?
Two to four RF microneedling sessions are typically recommended, depending on the concern being treated. Cleveland Clinic reports that most patients receive two to three treatments. In a study of the lower face, jawline and neck, patients had 1 to 3 sessions spaced 4 to 12 weeks apart. Your provider sets the number and spacing of sessions after examining your skin. Keep in mind that results may fade, and maintenance treatments may be needed later.
How long does it take to see results from RF microneedling?
RF microneedling results build gradually, and the best results typically appear 3 to 6 months after the first treatment. The delay happens because new collagen forms slowly. A review of 42 higher-quality studies found that skin continued to improve even 6 months after treatment. RF microneedling can't match the results of a facelift or other surgery. The FDA notes that any improvement may be temporary and maintenance may require more procedures over time.
Is RF microneedling better than regular microneedling?
RF microneedling adds heat to regular microneedling, which can boost collagen production and adds a tightening effect. The American Academy of Dermatology says combining radiofrequency with microneedling can make acne scars less noticeable than either treatment alone. The heat also brings different risks, and the FDA has warned of reported burns, fat loss and nerve damage with RF devices. A provider can help you weigh which fits your skin and goals.
What is the downtime after RF microneedling?
RF microneedling has little downtime, and most people return to normal routines within a day. Skin is usually mildly red for around 24 hours. In one acne scar study, the longest reported, redness lasted an average of 7.8 days. Aftercare typically includes skipping makeup for 24 to 48 hours, avoiding the sun for 2 weeks and keeping your head raised for 48 to 72 hours after facial treatment. If you have problems after treatment, see a licensed health care provider.
Is RF microneedling safe for dark skin?
Yes, the American Academy of Dermatology says RF microneedling is safe for all skin tones, though research in darker skin is still limited. Temporary dark spots (post-inflammatory hyperpigmentation) were reported in five acne scar studies of people with skin types III to V, and they faded during follow-up. The FDA notes that some microneedling devices weren't studied in darker skin. Ask your provider about their experience treating your skin tone.
Can a primary care provider evaluate you for RF microneedling?
Yes, a primary care provider can review your health history, medicines and skin to decide whether RF microneedling is a safe option. At GENEVA in Alpharetta, a provider evaluates your concern and then recommends treatment at GENEVA or a referral to a specialist. The review matters because blood thinners, isotretinoin within the past 6 months, pregnancy, keloid scars and a weakened immune system can make microneedling unsuitable. The FDA advises choosing a licensed provider trained and experienced in RF microneedling.
