Radio Frequency Microneedling: The Advanced Approach to Skin Rejuvenation

If you're noticing fine lines, wrinkles, loss of firmness, acne scarring, uneven texture, stretch marks or crepey skin, you may have heard about Radio Frequency Microneedling (RF Microneedling).

But what exactly is it?

How is it different from traditional microneedling?

And why is RF Microneedling considered an advanced treatment for concerns such as acne scarring, skin laxity and ageing skin?

What is RF Microneedling?

Radio Frequency Microneedling combines two technologies:

Microneedling + Radio Frequency energy

Very fine, sterile needles are introduced into the skin to create controlled micro-injuries. Radio frequency energy is then delivered through the needles at a controlled depth within the skin.

The RF energy creates controlled heat within the dermis, stimulating the skin's natural healing and remodelling response.

This can encourage the production and restructuring of collagen and elastin, helping improve the appearance of skin firmness, texture and overall quality.

Unlike treatments that work primarily at the surface, RF Microneedling allows energy to be delivered at a specific depth within the skin.

This is what makes it such an interesting treatment for skin remodelling rather than simply surface exfoliation.

RF Microneedling vs Traditional Microneedling

Traditional microneedling and RF Microneedling both use controlled micro-injuries to stimulate the skin.

The key difference is the addition of radio frequency energy.

Traditional Microneedling

Traditional microneedling creates controlled microchannels within the skin. More surface level.

It can be used to improve:

• Fine lines

• Skin texture

• Enlarged pores

• Acne scarring

• Uneven skin

• Overall skin quality

The primary stimulus is mechanical collagen induction.

RF Microneedling

RF Microneedling combines the mechanical action of the needles with radio frequency energy delivered into the dermis.

The RF energy produces controlled thermal stimulation at the treatment depth, providing an additional stimulus for collagen remodelling.

In simple terms:

Traditional Microneedling = controlled needling

RF Microneedling = controlled needling + controlled RF energy

Traditional microneedling can be an excellent treatment in its own right. However, RF Microneedling offers an additional thermal component, making it particularly useful when we are looking at concerns involving skin laxity, deeper textural changes and collagen remodelling.

What is RF Microneedling Considered the Gold Standard For?

There isn't one treatment that is the gold standard for every skin concern.

However, RF Microneedling is considered an advanced, evidence-supported treatment option for several concerns, particularly:

Acne scarring

RF Microneedling has a strong evidence base for the treatment of atrophic acne scars.

Research has found improvements in acne-scar severity, with a recent systematic review reporting consistent reductions in scar scores and efficacy comparable with fractional laser treatments in the studies reviewed.

Skin laxity and ageing skin

RF Microneedling can stimulate collagen remodelling and has been studied for facial and neck wrinkles, laxity and photoageing.

Clinical research has demonstrated improvements in facial and neck wrinkles and laxity following fractional RF treatments.

Skin texture and enlarged pores

By stimulating collagen remodelling, RF Microneedling can help improve uneven texture and the appearance of enlarged pores.

Stretch marks

RF Microneedling has also been investigated for striae (stretch marks), with evidence showing potential improvements, although results vary depending on the type and age of the stretch marks.

So rather than calling RF Microneedling a universal "gold standard", it is more accurate to describe it as an advanced collagen-remodelling treatment with evidence across a range of skin concerns.

What Areas Can RF Microneedling Treat?

RF Microneedling isn't just a facial treatment.

Depending on the individual, treatment area, device and treatment protocol, it may be used to address concerns across the face, neck and body.

Face

RF Microneedling can be considered for:

• Fine lines and wrinkles

• Loss of firmness

• Mild to moderate skin laxity

• Acne scarring

• Enlarged pores

• Uneven skin texture

• Photoaged skin

• Overall skin quality

• 
  

Jawline and Jowls

As we age, collagen and elastin decline and the skin can gradually become less firm.

RF Microneedling may be incorporated into a treatment plan to improve the appearance of laxity around the:

• Lower face

• Jawline

• Jowls

• 
  

The aim is to improve skin quality and firmness, rather than simply adding volume.

Neck Lines and Neck Laxity

The neck is often one of the first areas to show signs of ageing.

RF Microneedling can be used to target concerns such as:

• Horizontal neck lines

• Fine lines

• Crepey neck skin

• Reduced firmness

• Loss of elasticity

Clinical studies have investigated fractional RF treatments specifically for facial and neck wrinkles and laxity.

Crepey Arms

Crepey skin on the upper arms is a common concern, particularly as collagen and elastin decline with age.

RF Microneedling can be used to target the quality and texture of crepey skin, helping stimulate collagen remodelling within the treated area.

It is not a weight-loss treatment and should not be confused with fat reduction or body contouring.

The goal is skin rejuvenation and improvement in skin texture and firmness.

Stretch Marks

Stretch marks are a form of dermal scarring caused by changes within the skin.

RF Microneedling may be used to stimulate collagen remodelling within affected areas and improve the appearance and texture of stretch marks.

Treatment response can depend on whether the stretch marks are newer or more established, their colour, depth and individual skin characteristics.

How Many Treatments Will I Need?

There is no universal number of treatments.

Your treatment plan should be based on:

• Your skin condition

• The concern being treated

• Severity of the concern

• Treatment area

• Your individual healing response

• The device and settings being used

For many skin-rejuvenation programmes, a course of approximately four-six treatments may be recommended, although some concerns may require fewer or additional sessions.

RF Microneedling works through collagen remodelling, so improvements are gradual rather than instant.

Your skin continues to change for weeks and months following treatment.

This is why I believe realistic expectations are so important.

One treatment may produce an improvement, but a course is often recommended when the aim is more significant collagen remodelling.

What Happens During RF Microneedling?

Your treatment begins with a consultation and assessment of your skin and concerns.

A topical anaesthetic may be used where appropriate.

The RF Microneedling handpiece is then applied to the treatment area.

The needles enter the skin to a controlled depth and the RF energy is delivered according to the individual treatment plan.

You may experience warmth, pressure, prickling or heat during the procedure.

Immediately afterwards, the skin may appear red and feel warm or tight. Some swelling, sensitivity or pinpoint bleeding can occur depending on the treatment settings and individual response.

What is the Aftercare?

Aftercare is an important part of your treatment.

Your personalised aftercare instructions will always take priority, but you will generally be advised to:

• Keep the treated area clean.

• Avoid unnecessarily touching the skin.

• Use only recommended post-treatment skincare.

• Avoid retinoids, exfoliating acids and other potentially irritating active ingredients until advised to restart them.

• Avoid excessive heat such as saunas and steam rooms.

• Avoid strenuous exercise for the period advised.

• Avoid swimming until the skin has sufficiently recovered.

• Avoid picking, scratching or exfoliating the treated area.

• Protect the skin from UV exposure and use an appropriate broad-spectrum SPF.

Your skin may feel dry, tight or rough while it heals.

This is part of the recovery process, so don't rush it.

How Much Downtime Should I Expect?

RF Microneedling is often chosen because it can provide significant skin stimulation without the same downtime associated with some more aggressive resurfacing procedures.

However, minimal downtime does not mean no downtime.

Redness, warmth, swelling and sensitivity are common immediately after treatment.

Depending on the treatment settings and your individual response, you may also experience pinpoint bleeding, bruising, crusting or temporary changes in pigmentation.

These effects generally settle as the skin heals, but your practitioner should explain the expected recovery period before treatment.

Why Have RF Microneedling?

There are many reasons someone may choose RF Microneedling.

You want to stimulate your own collagen

RF Microneedling works with your body's natural healing response to encourage collagen remodelling.

You're noticing early skin laxity

It may be suitable for concerns involving reduced firmness in areas such as the face, jawline and neck.

You have acne scarring

It has a particularly strong evidence base for atrophic acne scarring.

Your skin texture has changed

It may help improve uneven texture, enlarged pores and overall skin quality.

You have crepey skin

It can be used on areas such as the upper arms where skin has become thinner-looking, loose or crepey.

You have stretch marks

It may help improve the appearance and texture of stretch marks through collagen remodelling.

You want gradual, natural-looking rejuvenation

RF Microneedling isn't about changing your face.

It's about improving the quality, firmness and texture of your own skin.

Is RF Microneedling Safe?

RF Microneedling is a medical procedure and should be treated as such.

The treatment requires appropriate practitioner training, correct patient selection and careful control of the device settings.

Importantly, more energy does not automatically mean better results.

In 2025, the FDA issued a safety communication highlighting reports of serious complications with certain uses of RF Microneedling, including burns, scarring, fat loss and nerve damage. This reinforces why treatment should be carried out by an appropriately trained professional using the correct device, settings and technique.

This is also why I believe safety should always come before chasing maximum intensity.

The objective isn't to cause as much damage as possible.

The objective is to create a controlled treatment response that your skin can safely recover from.

The Bottom Line

RF Microneedling is an advanced skin-rejuvenation treatment combining microneedling with radio frequency energy.

It can be used to address a wide range of concerns, including:

Fine lines • wrinkles • acne scarring • enlarged pores • skin laxity • neck lines • crepey arms • stretch marks • uneven texture • photoaged skin

It is particularly interesting because it doesn't simply work on the surface of the skin.

By combining controlled needling with RF energy delivered at a specific depth, it provides a powerful stimulus for collagen remodelling and skin rejuvenation.

But good results take time.

Your skin didn't age overnight — and it won't rebuild collagen overnight either.

A considered treatment plan, realistic expectations and good aftercare are all part of achieving the best possible outcome.
