What it does in the skin
RF microneedling is also called radiofrequency microneedling, gold RF microneedling or 黄金微针. Insulated needles pass through the outer skin and release energy only from the exposed tip, inside the dermis. Non-insulated needles warm the skin along the whole shaft.
The aim is remodelling of collagen and elastin, not resurfacing. RF has no light target, so the radiofrequency part is not a laser. The change is gradual and continues under the surface for weeks to months. Results vary, and no one can promise that a scar will disappear.
The RF microneedling device we use in Singapore
Dr Sin Yong uses the Secret DUO platform by ILOODA. It pairs RF microneedling with a 1540 nm non-ablative fractional laser. Needle depth adjusts from about 0.5 to 3.5 mm. Depth and energy are set for each zone, deeper over the cheeks and jaw, and more cautious near the eyes and over bone. Needle-only microneedling with pens or rollers is a separate treatment. It is not offered by itself here, and it is used only as a route for a skin booster or sequenced with RF. Home dermarollers and pens are discouraged because of depth and sterility. Insulated needles are generally preferred in darker skin types. Evidence sits at the level of RF microneedling as a type of treatment, not at individual devices, so a device name alone tells you little.
Who may suit it
Rolling and shallow boxcar scars.
Enlarged pores and oily, congested skin, as one part of a wider acne plan.
Rough, uneven skin and static fine lines. Expression lines are a different problem.
Along the jaw and lower face, before jowls form.
Fitzpatrick III to V, with settings chosen for pigment risk. Pigment history is part of the assessment.
In some plans, as one part of the 4K Body Lift. Suitability depends on what the examination finds.
Who should wait or need a different plan
Active infection, inflamed acne or open wounds in the area. Pregnancy. Recent oral isotretinoin.
A pacemaker or other implanted electronic device. Metal or gold-thread implants in the area. Keloid or hypertrophic scarring tendency. Bleeding tendency or blood thinners. A history of cold sore flares.
Tethered scars need subcision first. Deep ice-pick scars need TCA CROSS first. Heavy skin excess needs a surgical assessment. Melasma or rosacea as the main concern is planned separately.
What it cannot do
It cannot release tethered scars or deal alone with deep ice-pick scars. It will not clear pigment or lift deeper laxity, which goes to HIFU or other lifting options. It cannot shrink pores for good, and it can only firm the collagen around them. It does not replace a laser, though some plans stage the two together. See our acne scar laser page. If you expect pores to change outright, it is better to wait and talk it through.
Where it fits in a scar plan
RF microneedling is often one step in a sequence, not a whole plan. Tethered scars are released first. Deep ice-pick scars are treated first with TCA CROSS. Where laser is also used, it is staged. If acne is still active, that comes first too. It can also be combined with a skin booster in some plans. Your doctor explains the order for your skin.
How a treatment runs
Recovery
Expect redness and pinpoint marks at first. How much depends on depth, energy and skin type. On the first evening, use only a bland cleanser and moisturiser. Do not use actives, do not put make-up over open channels, and do not pick at scabs. Over the next days, redness fades and the marks flake. Strict sun protection matters most in Fitzpatrick III to V skin. Make-up, swimming, saunas and hard exercise wait until the skin has settled, and you are given timing on the day. Work and event plans are discussed beforehand.
Side effects and risks
Redness, pinpoint marks, pressure and warmth, and tightness like sunburn.
Post-inflammatory pigmentation, more so without sun avoidance. Prolonged redness, small scabs or crusting, infection, cold sore or acne flares, and scarring in keloid-prone people.
Burns or uneven heating. Correct depth, energy and cartridge choice reduce this.
Worsening redness, rising pain, swelling or weeping, pus or spreading yellow crusts, fever, blistering, dusky or dark skin, or a cold sore flare.
Results and fees
No duration is promised. The first redness and tightness are part of healing and do not show the outcome. Progress is judged at review. How long a change holds depends on the concern, settings, skin, sun exposure, smoking and any combined treatment. Fees are not published. They depend on the area, findings, cartridges and consumables, the number of zones and passes, and any combination with laser, subcision or TCA CROSS.
