Microneedling Gangnam: RF vs. Traditional Needling

How Microneedling
Stimulates Collagen

Microneedling uses fine needles to create controlled micro-injuries across the skin, triggering the body’s natural wound-healing response and prompting new collagen production. RF microneedling adds radiofrequency energy through the same needles, adding heat in the dermis on top of the needle injury, which is why clinics offer it when firmness is part of the goal. It’s frequently paired with active acne treatment once breakouts are under control, since the same mechanism supports scar remodeling afterward.

RF Microneedling vs.
Traditional Microneedling

Numbing cream is usually applied first. How long the session takes depends on the area treated and the device, so ask the clinic before you book.

Recovery and
Session Schedule

The AAD notes that redness on lighter skin, or darker patches on darker skin, usually clears in a few days to a week, with some pinpoint bleeding possible immediately afterward for deeper settings. Collagen continues building for weeks after each session, which is part of why the full course is spaced out rather than done all at once.

For scarring concerns specifically, our acne scar removal guide goes into scar-type-specific approaches, and the broader skin rejuvenation overview explains how microneedling fits alongside PRP and other options.

Frequently Asked
Questions

Does microneedling hurt?

Numbing cream applied before treatment keeps most sessions tolerable, though deeper settings used for scarring can feel more intense. Most patients describe it as manageable discomfort rather than significant pain.

Is microneedling effective for acne scars?

Yes, for many atrophic scars. A 2020 systematic review found improvement in all 33 studies it examined, and the AAD reports that a course of treatment can fade acne scars by 50% to 70%. Results build gradually over several sessions rather than appearing after just one.

Can microneedling be combined with vitamin infusions?

Yes, applying a growth-factor or vitamin serum immediately after microneedling is common since the micro-channels created allow for better absorption. This combination is often marketed as an added boost to the standard treatment.

Is microneedling safe for all skin types?

The AAD describes microneedling as safe for all skin tones, but the FDA lists pigment changes as a possible risk and advises caution for darker skin types. The FDA also lists bleeding disorders, blood thinners, active infection or cold sores, keloid scarring, recent isotretinoin use, pregnancy and breastfeeding as reasons to hold off or discuss the risks first.

How far apart should sessions be scheduled?

For acne scars the AAD gives 2 to 4 weeks between sessions, which lets the collagen response progress before the next round. Your clinic may adjust this based on how your skin healed after the first session.

Sources &
Verification Notes

Where we found a real, checkable source for a claim above, we’ve linked it here. Where we couldn’t, or found the approved indication narrower than common marketing language, we say so rather than leaving it unstated.

• Regulatory status: microneedling for aesthetic use is FDA Class II under 21 CFR 878.4430, a classification that originated from SkinPen’s 2018 De Novo review. RF microneedling devices are cleared separately and sometimes carry a narrower original indication (e.g. “electrocoagulation and hemostasis” in general surgery) with cosmetic remodeling claims added via later submissions, so it is worth checking what a specific device is actually cleared for. Source: Federal Register, FDA classification.
• We did not find a specific, independently verifiable MFDS record for named RF microneedling devices commonly used in Korean clinics (e.g. Secret RF, Potenza). These are widely used, but we have no primary source to cite for their individual MFDS approval status.
• Clinical evidence: systematic review of fractional RF microneedling used alone for acne scars (16 studies, 481 patients), Clinical, Cosmetic and Investigational Dermatology, January 2025. Source: PubMed 39781098.
• Sessions, recovery and who should wait: American Academy of Dermatology, microneedling and FDA, Microneedling Devices. The FDA also advises confirming that a new, sterile needle cartridge is used for each patient.
