Radiofrequency microneedling in London

Needles that deliver heat into the dermis: what that adds over standard microneedling, who it suits, and the settings question that matters on a thin face.

In short

What is radiofrequency microneedling?

Radiofrequency microneedling drives fine needles into the dermis and delivers heat through their tips. The combination of mechanical injury and controlled thermal injury produces more remodelling than needling alone. It is used for texture, scarring and mild laxity, and it carries more risk.

What the energy adds

Standard microneedling relies on mechanical injury alone. Radiofrequency devices add a second mechanism: current passes between or from the needle tips once they are in the dermis, heating the surrounding tissue to a temperature intended to denature collagen and trigger a stronger remodelling response.

In practice that means more change per session, and a treatment that reaches deeper structures than needling alone. It also means a thermal injury has been placed inside your dermis, which is a more consequential act than a puncture, and one that depends entirely on the settings chosen.

Insulated and non-insulated needles

This distinction matters and is rarely explained to patients.

Insulated needles
Coated along the shaft so that energy is delivered only at the tip, deep in the dermis. The epidermis is spared most of the thermal injury. Generally preferred in darker skin types because the pigmentation risk is lower.
Non-insulated needles
Deliver energy along the whole shaft, including the upper skin. More surface effect, more downtime, and a higher risk of pigment change in skin that is prone to it.

Neither is universally better. The point is that a practitioner should be able to tell you which the device uses, why that suits your skin, and what depth and energy they are setting.

Who it suits

  • Atrophic acne scarring, particularly boxcar and rolling types, where it is one of the better tolerated options in skin of colour.
  • Textural irregularity and enlarged-looking pores that have not responded to needling.
  • Mild laxity in the lower face and along the jaw, with realistic expectations.
  • Skin that is too pigmented for aggressive ablative laser.

Poor candidates:

  • Very thin faces with little subcutaneous fat, where the atrophy risk is highest.
  • Anyone with active acne or active skin infection.
  • Anyone with an implanted electronic device, unless specifically cleared.
  • Anyone expecting a surgical degree of lifting.
  • Anyone unable to protect their skin from sun for the following weeks.

The fat atrophy question

The complication that distinguishes this treatment from standard microneedling is loss of subcutaneous fat where energy has been delivered too deep or too aggressively. The result is a hollow or a shadow that appears in the weeks or months afterwards and that does not resolve on its own.

It is uncommon, it is more likely in thin faces and in the temples and lower cheeks, and it is a settings problem rather than an inevitability. It is also a good reason to prefer a practitioner who treats conservatively and stages sessions, over one who promises a dramatic single-session change.

A question worth asking directly

Ask what depth and energy they are using in each area, whether they reduce settings over the temples and lower cheeks, and whether they have ever seen fat atrophy after treatment. A practitioner who engages seriously with that question is the one you want.

Treatment and recovery

Numbing cream is applied for around forty five minutes, sometimes longer than for standard needling because the treatment is more uncomfortable. The device is passed over the area in a grid pattern, often with more than one pass at different depths.

  • Day 0: red, swollen, hot. A visible grid pattern is normal.
  • Day 1 to 2: peak swelling, particularly around the eyes.
  • Day 3 to 5: redness settling, small dark grid marks may be visible.
  • Week 1 to 2: skin dry and rough, then improving.
  • Month 1 to 3: remodelling. This is where the result comes from.

Aftercare is the same in principle as for needling but stricter: gentle cleansing only, bland moisturiser, no actives for around a week, no heat or exercise for forty eight hours, and daily broad-spectrum sun protection without exception. See aftercare.

Risks

  • Post-inflammatory hyperpigmentation, more likely with non-insulated needles and in darker skin types.
  • Prolonged redness.
  • Grid marks persisting for days.
  • Burns, where energy or contact is uneven.
  • Fat atrophy, as described above.
  • Infection, including reactivation of cold sores.
  • Underwhelming result where the wrong finding was targeted.

Comparing it with the alternatives

Versus standard microneedling
More change per session, more downtime, more risk, higher cost. For general skin quality standard needling is often sufficient. For scarring and laxity, the energy usually earns its place.
Versus fractional laser
Laser tends to do more for surface texture and pigment. Radiofrequency reaches deeper with less epidermal disruption, which is why it is often preferred in skin of colour.
Versus focused ultrasound
A different depth and a different aim. Ultrasound targets deeper support structures for tightening and does little for surface texture.

See laser resurfacing and microneedling to compare directly.

Common questions

How is it different from normal microneedling?

It adds controlled heat delivered into the dermis through the needles, producing more remodelling per session along with more downtime and more risk.

How many sessions?

Typically three, four to eight weeks apart, with the result assessed three months after the last.

Does it hurt more?

Yes. Numbing is applied for longer and the sensation is a deep heat rather than a scratch.

What is the grid pattern on my skin?

Small marks where the needles entered, normal in the first days after treatment and settling over roughly a week.

Can it cause fat loss?

It can, where energy is delivered too deep or too aggressively, particularly on thin faces. It is uncommon and it is a settings issue.

Is it safe for darker skin?

It is often preferred over ablative laser, especially with insulated needles, which spare the epidermis most of the thermal injury.

Will it tighten my jawline?

Modestly, in mild laxity, over months. It is not a substitute for surgery and should not be sold as one.
