In brief
Fractional radiofrequency microneedling, also called needle radiofrequency, is an intimate medicine treatment, with no scalpel: ultra-fine microneedles enter the skin and release heat directly into the dermis, stimulating new collagen. I use it on the skin of the external genitals and the surrounding areas (labia majora, mons pubis, groin and inner thigh) for laxity, stretch marks, scars and dull skin, also together with filler or fat grafting (lipofilling). It is not vaginal radiofrequency, which I do not perform. Usually 3 sessions are needed; on the genital area the studies are still few and small.
What fractional radiofrequency microneedling is
It is a technique that combines two stimuli. A handpiece with a series of ultra-fine microneedles penetrates the skin to a depth that I choose area by area; radiofrequency, that is, energy that is converted into heat, is released from the tips of the needles. This creates many small columns of heat in the dermis, separated by intact skin: this is why the treatment is called "fractional".
The stimulus is twofold. The tiny needle perforations trigger the skin's normal healing mechanisms; the heat of the radiofrequency immediately contracts the existing fibres and, above all, starts a repair process in which fibroblasts, the skin cells that produce collagen and elastin, make new ones (mainly type I and type III collagen). The result is firmer, more even skin with a finer texture, which builds up slowly over the following months.
How it differs from conventional radiofrequency
The name "radiofrequency" covers treatments that are very different from one another, and it is easy to confuse them.
| Conventional radiofrequency | With microneedles | |
|---|---|---|
| How it works | Heats the tissues from the surface, with a handpiece placed on the skin or inserted into the vagina | Delivers heat directly into the dermis through the microneedles, at the chosen depth |
| Depth | Works from the surface: the heat reaches the layers below by conduction | Adjustable, according to needle length and the area |
| Skin surface | Intact | Largely intact, with micro-perforations between the needles |
| Where | External skin or vagina | Skin of the labia majora, mons pubis, groin |
| Aim | Mild laxity | Skin tone and quality, stretch marks, scars |
| In my practice | I do not perform it | Yes |
Areas where I use it
- Labia majora: lax, thin or wrinkled skin, with the "deflated" appearance that develops with age, after the menopause or after weight loss.
- Mons pubis: skin laxity, often after weight loss or after pregnancy.
- Groin and inner thigh: lax skin, stretch marks and signs of ageing in the transition area between the genitals and the thighs.
Which problems it is suitable for
- Mild or moderate skin laxity, when the skin has lost tone but there is no large excess to remove.
- Stretch marks and scars, including those of the groin area: radiofrequency microneedling softens them, it does not erase them.
- Dull skin and uneven texture: it improves the overall quality of the skin. On dark patches the results are variable and, in more pigmented skin, the treatment itself can leave temporary ones.
- Together with filler or fat grafting: volume of the labia majora is restored with filler or fat grafting (lipofilling), while radiofrequency improves the skin that covers it. The two complement each other.
What it cannot do
How it is carried out
The session
It is done as an outpatient procedure. After cleansing and disinfecting the area, I apply an anaesthetic cream and, in some cases, add local anaesthesia with small injections to make the treatment more comfortable where the skin is more sensitive. I then pass the handpiece over the area to be treated, adjusting depth and energy to the thickness of the skin. During the session you feel warmth and prickling. The session takes about 30 minutes.
How many sessions
Usually 3 sessions, 4–6 weeks apart. Collagen renews slowly: the improvement appears gradually, usually over the 2–3 months after the last session, and that is when the result is assessed.
After the session
- Common effects: redness, swelling and small pinpoint marks or scabs for a few days.
- Daily activities: these can generally be resumed straight away.
- For a few days: it is best to avoid swimming pools, saunas, intense sport, tight clothing that rubs and, until the skin has healed, sexual intercourse. I give you precise written instructions.
What the studies say, honestly
Radiofrequency microneedling is widely used in dermatology, especially on the face and on stretch marks, where reviews of the studies show a real but moderate improvement in skin quality, with side effects that are generally mild and temporary.
On the genital area, however, there are few studies. The most relevant is a Brazilian randomised study of 30 postmenopausal women (Maia, 2022): after 2 sessions on the labia majora laxity improved and biopsies showed signs of tissue regeneration. However, it is a small study, with a follow-up of only two months and no untreated group. I have not found studies specifically on the mons pubis or the inner thigh.
Some studies on the labia majora report very impressive results, but they use different technologies, such as probes inserted under the skin, and they are often small and funded by the manufacturers. For this reason I do not promise a precise result: at the consultation I explain what it is reasonable to expect in your case.
Prima comprendere ("Understand first"): the consultation
At the first consultation, which lasts from half an hour to an hour, we look at the area together and work out what really bothers you: whether the problem is the quality of the skin, the volume or an excess to be removed, because the solutions are different. I ask whether you tend to develop dark patches or raised scars, whether you have had genital herpes and whether you take medicines that slow healing. If radiofrequency microneedling is suitable for you, I explain the sessions, timescales and risks; if it is not, I tell you so.
Risks and side effects
- Redness, swelling, burning and small pinpoint marks, all temporary.
- Temporary dark patches (post-inflammatory hyperpigmentation), more likely in dark skin and in the genital area, which is naturally more pigmented.
- Reactivation of genital herpes in those who have had it before: in these cases it can be prevented with antiviral treatment before the session.
- Infection, rare.
- Burns, scarring, loss of subcutaneous fat or nerve damage: rare, reported in the FDA's 2025 warning.
- Lack of benefit: not all patients respond in the same way.
Frequently asked questions
What is fractional radiofrequency microneedling?
It is an intimate medicine treatment, with no scalpel, in which ultra-fine microneedles enter the skin and release radiofrequency energy directly into its deeper layers. The heat stimulates the production of new collagen and elastin, to improve the tone and quality of the skin of the labia majora, mons pubis and groin.
How is it different from conventional radiofrequency?
Conventional radiofrequency heats the skin from the outside, through the surface, or from inside the vagina. With microneedles the energy is delivered directly into the dermis, at the chosen depth, and the surface remains largely intact between one needle and the next: the stimulus is deeper and more precise.
Is it also done inside the vagina?
No. I use radiofrequency microneedling only on the skin of the external genitals and the surrounding areas. I do not perform vaginal radiofrequency because, in my experience, the results are unsatisfactory; for dryness and fragility of the vaginal lining I use other treatments.
Which areas can be treated?
The labia majora, the mons pubis and the skin of the groin and inner thigh.
Does it restore volume to the labia majora?
No. It improves the tone and quality of the skin, not the volume. If the labia majora have lost volume, this is restored with filler or with fat grafting (lipofilling), and radiofrequency can be combined with them to complete the result.
Does it hurt?
Before the session I apply an anaesthetic cream and, in some cases, I add local anaesthesia with small injections. During the treatment you feel heat and a prickling sensation, which are generally well tolerated.
How many sessions are needed?
Usually 3 sessions, 4–6 weeks apart. Collagen renews slowly: the improvement usually appears over the 2–3 months after the last session.
Does it work?
On the genital area there are still few studies: the most relevant is a randomised study of 30 postmenopausal women, which showed improved laxity of the labia majora at two months. On the face and on stretch marks the evidence is broader. It is not possible to promise a precise result.
What are the risks?
Redness, swelling and small pinpoint marks for a few days are common. Rarer are temporary dark patches, especially in more pigmented skin, and, very rarely, burns, scars or loss of subcutaneous fat, which were also reported by the FDA in 2025.
Does it replace surgery?
No. When there is a lot of excess skin, for example on the mons pubis after major weight loss, the result of radiofrequency is limited and surgery is needed, such as monsplasty.
