Understanding mnrf — microneedling radiofrequency
Insulated needles pass through the epidermis and release radiofrequency energy at a set depth, so heating occurs where remodelling is wanted while the skin surface is comparatively protected.
That surface protection is why MNRF is often preferred in deeper skin tones, where ablative resurfacing carries a higher pigmentation risk. Needle depth is adjusted by facial zone.
MNRF suits acne scarring, enlarged pores and early laxity. As with all collagen procedures, improvement accumulates across sessions and continues for months after the last one.
This may suit you if
- Acne scars, particularly with associated laxity
- Enlarged pores and uneven texture
- Early skin laxity on the face or neck
- Skin types at higher risk of pigmentation with ablative lasers
What happens at the clinic
- 1
Assessment
Scar type, skin thickness and laxity are assessed, and depths are planned zone by zone.
- 2
Numbing
Topical anaesthetic is applied for 45 to 60 minutes before treatment.
- 3
Treatment passes
The handpiece is applied in a systematic pattern with depth and energy adjusted by area. Deep warmth is felt during treatment.
